Daily Question: [2011.7.14] How many devices in the gasification unit are considered oversized devices?

Overdimensional equipment generally refers to such equipment used in railway transportation; see the attached document. In gasification units, the equipment that exceeds specified limits varies depending on the scale and gasification process; for gasifiers with a capacity of less than 1,000 tons for water-coal slurry, it is mainly the mills and vacuum flash tanks that exceed these limits. Settling tanks and slurry tanks are fabricated on-site. The situation is different for SHELL technology and Lurgi technology. The main concerns are: coal mills, gasifiers, waste boilers, vacuum flashers, high-pressure nitrogen tanks, heat drying ovens, etc. See below for the requirements: Rules for the Transport of Railway Goods That Exceed Dimensions or Weight Limits. Article 1 – General Provisions: These rules are formulated in accordance with relevant laws and regulations such as the Railway Law of the People’s Republic of China, the Regulations on the Safety Protection of Railway Transport, the Technical Management Regulations for Railways, and the Regulations on Railway Freight Transport, in order to standardize the transport of railway goods that exceed dimensions or weight limits and ensure transportation safety. Article 2 These rules apply to **railways with standard gauge, joint-venture railways, local railways and dedicated railways, as well as railway sidings; they serve as the basic basis for the transportation of oversized and overweight goods by railways. The carrier, shipper, and consignee shall all comply with these rules. Article 3: The transportation of oversized and overweight goods is of great significance for meeting the needs of **key infrastructure projects and national defense construction, as well as for promoting sound and rapid development of the national economy. Railway authorities at all levels must attach great importance to this matter, strengthen organizational leadership, and assign dedicated personnel to oversee the transportation of such goods. The railway bureau shall establish a Railway Bureau Committee for the Transportation of Overdimensional and Overweight Goods and Gauge Management, with the deputy director in charge of transportation as chairman, the chief engineer as vice chairman, and the heads of relevant departments as members. The freight stations and railway depots directly under the railway bureau should establish a leadership team for the transportation of oversized and overweight goods, with the station or depot managers as its leaders. The management committee and leading group should establish working procedures, define responsibilities, and be responsible for coordinating and resolving major issues arising in the transportation of oversized and overweight goods. Article 4: When handling the transport of oversized or overweight goods on each main railway line (section) and at each station (including dedicated railways and sidings), the carrier must obtain the necessary qualifications and permits as required by regulations. Chapter 2 Definitions and Classification Article 5: After the goods are loaded onto the vehicle, if the vehicle remains on a horizontal straight line and any part of the goods exceeds the basic outline of the limits for locomotives and vehicles, or if, when the vehicle moves along a curve with a radius of 300 meters, the calculated width of the goods exceeds the basic outline of those limits, such goods are considered oversized goods. The rolling stock gauge diagram is shown in Attachment 1. The method for calculating the width of the goods is shown in Attachment 2. Article 6: Based on the degree of excess dimensions of the goods, oversized goods are classified into three categories: Class 1 oversized, Class 2 oversized, and Super oversized. 1. Grade 1 excess: A height of 1250 millimeters or more above the rail surface, but not exceeding the limits for Grade 1 excess ； 2. Secondary excess: Those that exceed the limits for primary excess but not the limits for secondary excess, as well as those whose height above the rail surface is between 150 millimeters and less than 1250 millimeters, exceeding the limits but not reaching the level of secondary excess ； 3. Super-excessive: Those exceeding the limits for level 2 excess. The overlimit limits charts for various levels are shown in Attachment 3. The table showing the dimensions in the vertical plane perpendicular to the line centerline for the rolling stock clearance, various types of over-limit clearances, and building clearances is provided in Appendix 4. Article 7: Based on the height of the part of the cargo that exceeds the limits, oversized cargo is divided into three types: upper oversized, middle oversized, and lower oversized. 1. Upper excess: The height from the rail surface exceeds 3600 millimeters, in case of excess at any part ； 2. Central excess height: The height measured from the rail surface ranges from 1250 millimeters to 3600 millimeters; any excess in this range is considered a violation ； 3. Lower excess: Any part where the height from the rail surface is between 150 millimeters and less than 1250 millimeters. Article 8: Goods whose total weight, including the live load, after loading exceeds the design live load (medium-live load) specified for bridges and culverts are referred to as overweight goods. Article 9: Depending on the degree of excess weight, overweight goods are classified into three categories: Grade 1 overweight, Grade 2 overweight, and Super overweight. 1. Grade 1 overweight: 1.00＜Q≤1.05 ； 2. Secondary overweight: 1.05＜Q≤1.09 ； 3. Super-heavy: Q＞1.09. 　Note: Q is the live load factor. The overweight cargo classification table is shown in Attachment 5. Chapter 3: Shipment, Acceptance, and Carriage Article 10: When the shipper sends goods that are oversized or overweight, in addition to following the regular shipping procedures, the following information must also be provided: 1. A description of the oversized or overweight goods (Form 1), along with three views of the goods’ shape. The diagram should indicate the relevant dimensions of the goods, as well as the length of the load-bearing surface, and the center of gravity should be marked with a “+” sign. 2. For self-propelled freight cars, information on their own weight, number of axles, axle spacing, fixed axle distance, length, distance between the bogie center pins, type of braking system, and operational restrictions shall be provided. 3. The types, models, and number of vehicles to be used, along with the planned reinforcement plan. 4. Other specified materials. The shipper shall stamp or sign the declaration for shipping oversized and overweight goods, the planned loading and securing plan, as well as the provided documents, and bear full responsibility for the accuracy of their contents. Article 11: When accepting goods that exceed size or weight limits at the station, the station shall carefully examine the technical documents provided by the shipper, measure the dimensions of the goods and the location of their center of gravity, and if necessary, organize relevant departments to conduct joint discussions. After review, a telegram requesting permission for the transport of oversized and overweight goods was sent to the railway authority to inquire about the shipping procedures. For overweight and extra-large oversized goods at all levels that involve four or more railway bureaus, the relevant railway bureaus shall conduct a review and then submit a request to the Ministry of Railways. Article 12: The measurement of oversized goods is in millimeters. Measurements before and after loading shall be carried out in accordance with the following regulations. 1. Before loading, measure according to the planned loading and reinforcement plan: (1) Length: measure its maximum length, the length of the load-bearing surface, the distance from the center of gravity to the end, and the distance from the inspection section to the center of gravity. (2) Height: Starting from the load-bearing surface, measure its center height, side height, and center of gravity height. ①Center height: The height from the load-bearing surface to the maximum height is the center height ； ②Side height: The height from each measurement point below the center height to the load-bearing surface. If there are several different side heights, each distinct side height should be measured from top to bottom. (3) Width: Measure the width at the center height and the width at different side heights. ①Width at the center height: at the center height, the maximum width on the left and right sides of the vertical longitudinal plane where the cargo’s center of gravity lies ； ②Width at side height: At each side height, the maximum width on the left and right sides of the longitudinal vertical plane where the cargo’s center of gravity is located. 2. After loading, measure based on the actual loading and reinforcement condition (including reinforcement materials): (1) Length: ① When loaded across, measure the span distance and the length outside the two support points ； ②When protruding during loading, measure the length of the vehicle’s end beam that protrudes ； If the protrusions at both ends are not equal, they should be measured separately. (2) Height: The center height and side height are measured from the rail surface. (3) Width: Starting from the vertical plane containing the vehicle’s longitudinal centerline, measure the center height as well as the width on the left and right sides at different side heights. Article 13: Upon receiving a telegraph requesting the transportation of oversized and overweight goods, the Ministry of Railways and the railway bureaus shall issue instructions to the relevant units regarding the methods of shipment. The telegraphic codes for the transport of oversized and overweight goods are listed in Attachment 6. Article 14: Upon receiving directives or telegrams copied to it, the Railway Bureau shall promptly forward them in light of the actual conditions within its jurisdiction. For cases where temporary changes to buildings or fixed equipment are required, these should be specified in detail in the telegram. If there are indeed difficulties in passing through the pipeline, the issuing office and the party that issued the telegram should be notified by phone and telegram within three working days from the date of receipt of the telegram. Article 15: Upon receiving the telegram with instructions from the railway bureau, the station shall promptly organize loading in accordance with the loading and securing plan. If the measurements after loading do not match the indicated telegram, further approval must be sought. Article 16: Loading of telegrams without authorization for exceeding limits or weights is prohibited; a loading quality approval system shall be implemented. Article 17: After loading, the play between the side bearings on either side of the vehicle’s bogie must not be zero (except for freight cars whose design specifies constant-contact side bearings). In the case of a freight car with a spherical center disc where the play between the side bearings on one side is zero, a jack can be used to lift that side; once the side is raised, the appearance of play indicates that the cargo is loaded properly. When using drop holes or clamp-type vehicle loading methods, the distance between the bottom of the loaded goods and the rail surface must be at least 150 mm. Article 18: After loading, clearly marked inspection lines that make it easy to determine whether the cargo has moved should be drawn using brightly colored paint. On both sides of the cargo, the words “Grade X overdimensional, Grade X overweight” should be written, painted, or stuck on, or signs should be installed. Article 19: After loading the goods, the dispatching station shall fill out the record for the transport of oversized and overweight goods (Format 2), and indicate “oversized goods”, “overweight goods”, or “oversized and overweight goods” on the goods waybill, ticket, envelope for documents, and marshalling sequence sheet” ； When transported in a coupled train configuration, it should be specified that \"the coupled train set must not be separated\"” ； When operating at a limited speed, it should be indicated as “Limited speed: XX km/h”. And place the truck identification plate on the vehicle as required. Article 20: Before dispatching vehicles that exceed weight or size limits from the departure station, a telegraph requesting permission for the dispatch of such vehicles must be sent to the railway bureau’s dispatch office (a telephone request may also be made if the conditions do not permit it). Article 21: When goods that exceed size or weight limits are to be diverted to a different station, the station that handles the request shall measure the dimensions of the goods after they have been loaded, and then send a telegram to the railway authority for further approval, indicating the original approving authority, the telegram number, the new destination station, and the vehicle number. The station that accepts the change shall inspect the loading and securing condition of the goods and sign off on it in the \"Record of Transport for Overdimensional and Overweight Goods\". Article 22: For large equipment that exceeds size or weight limits, the shipper shall consider the feasibility of transporting it by rail during the design phase; if necessary, it should be manufactured in sections. For goods that pose difficulties in transportation, measures such as changing the packaging and disassembling the cargo should be taken to minimize any excess dimensions or weight. Article 23: Goods that, after loading, extend beyond the basic dimensions of the locomotive and rolling stock limits may, with the approval of the Ministry of Railways, be handled without being treated as oversized goods. Article 24: To ensure the safety of transporting extremely large and oversized goods, methods such as inspection frames may be used to check and confirm whether the limits of the transportation route or section can be satisfied. 1. The dimensions of the inspection frame should be identical to the actual dimensions of the cargo’s inspection cross-section. 2. The vehicle equipped with the inspection frame should be of the same model as the vehicle to be used. 3. The inspection frame should be installed at the location of the cargo inspection section. When using another vehicle to install the inspection frame, it should be installed at the cross-sectional position corresponding to the center pin of the vehicle’s bogie. The dimensions of the inspection frame must take into account the deviations and tilts of the vehicle to be used. Article 25: The railway bureau shall, by the 5th of each month, compile statistics on the number of shipments of oversized and overweight goods within its jurisdiction from the previous month in accordance with Format 6 and Format 7, and submit them to the Transport Bureau of the Ministry of Railways.
