Some introductions to aerospace gasification technology and its company
Thread Content
Aerospace gasification technology is the core technology of coal chemical projects developed by Beijing Aerospace Wanyuan Coal Chemical Engineering Technology Co., Ltd. Its core equipment is the space furnace mentioned in the altar. The company is an engineering and technical firm established through a joint venture between the China Academy of Launch Vehicle Technology and the Beijing Institute of Aerospace Propulsion, with the Gansu Provincial Branch being its subsidiary. In China’s chemical industry, Beijing Aerospace Power Research Institute (formerly Beijing No. 11 Institute) is believed to enjoy a certain level of reputation. Over the past few decades, the company has produced a large number of devices for China’s chemical enterprises in the field of petrochemical equipment. Space technology has been successfully applied extensively in the petrochemical industry, enabling the localization of a large number of key petrochemical equipment. We know that although the core technology of gasification is the gasifier, a series of other equipment is also extremely important! Products such as slag breakers, various special valves, safety valves, and special pumps are all mature products of this company. Some industrial furnaces have surpassed international counterparts in terms of performance due to the successful application of space-related technologies (the military products developed by Beijing Aerospace Power Research are rocket engines, and thermal field calculation is their core strength), and they have been in use successfully for many years. Most of the core technology R&D personnel at Beijing Aerospace Wanyuan Coal Chemical Engineering Technology Co., Ltd. are front-line technical staff involved in the company’s R&D work, possessing extensive experience in actual engineering design. The greatest advantage of aerospace gasification technology is that all its equipment is domestically produced, **which reduces the maintenance costs of the products. As for technical indicators, I believe facts must speak for themselves; the promotional figures must be backed by actual projects! The data in its promotional materials are merely design-related figures; the practical engineering applications of this technology are currently in the Puyang and Linquan projects, with both expected to come online in October 2008. But in my personal opinion, looking at large-scale projects in the same industry both domestically and internationally, an optimistic estimate would be that if just one project can start operating successfully by the end of the year and achieve stable production within that year, it would already be a tremendous success. If successful, both Shell and Texaco will likely face huge challenges in the domestic market. At the same time, it also provides strong support for China’s energy security strategy. The above are purely personal opinions; I welcome corrections from colleagues.
Agree with the opinion above, but there is still a certain gap between industrial and laboratory data; we’ll have to wait and see
A Record of the Birth of China’s First HT-L Pressurized Coal Gasification Furnace: The Development Journey of the “First Aerospace Furnace” March 2005: Beijing Institute 11 launched a coal chemical project codenamed “Project 301”. March 2006: China’s first domestically developed coal gasification demonstration project was set up in Puyang, Henan. September 2006: The second coal gasification demonstration project began operations in Linquan, Anhui. June 2007: Beijing Aerospace Wanyuan Coal Chemical Engineering Technology Co., Ltd. was established. September 24, 2008: China’s first HT-L pressurized coal gasification furnace was ready for testing. October 8: The first test run of the HT-L pressurized coal gasification furnace officially commenced. October 13: The furnace successfully processed coal on its first attempt, and the test run was a **success**. October 16–19: The HT-L pressurized coal gasification furnace operated continuously for 72 hours throughout this period
For the creation of the “first furnace for space industry” – after three and a half years of design and construction, the “first furnace for space industry” has finally entered its final stage of development. On September 24 of this year, all conditions for testing were fully met. The first trial run was intended to establish the process flow, and to actually verify the operational reliability of key equipment such as the gasification furnace, gasification burners, as well as pumps and valves. It also served to ensure the correctness and safety of the entire aerospace gasification process technology and the automatic control systems. It is reported that the HT-L coal pressurized gasification process represents a significant challenge. The main gasification section of this process consists of five steps: first, coal transportation and preparation; second, coal grinding and drying; third, pressurized transportation; fourth, gasification, synthesis, and washing; fifth, treatment of ash and slag water. September is the busiest and most stressful month for researchers, as they spend almost every day adjusting all the equipment and instruments in order to understand their behavior. Chief Engineer Lu Zhengtao, at the age of 70, possesses extensive theoretical and practical experience in coal-to-gas technology; with him on hand, any process-related technical issues that arise during commissioning can be resolved promptly. By participating in this project, Jiang Congbin, the deputy general manager of the coal chemical company, grew from an equipment management specialist to an expert in chemical processes within just over two years. Based on a solid understanding of logical theory, he managed complex control systems and, by analyzing system data, identified the root causes of system failures time and again, thereby ensuring the smooth progress of the debugging process. Deputy Chief Engineer Sun Qingjun is an experienced veteran who oversaw the entire testing process. He is familiar with every step of the testing procedure and knows the appropriate limits for moving forward or backward. It was he who ensured the orderly progress of the testing process. On October 8, the first test run officially began. “The \"first aerospace furnace\" moved directly from the engineering design phase to the stages of construction, commissioning, and testing. Moreover, the first test run had to overcome three challenges: the need for local sourcing of raw coal, cost reduction, and the use of domestically produced key equipment. As a result, employees at both the coal chemical company and Puyang Longyu Chemical Company, which belongs to Henan Yongmei Group, felt considerable pressure. At the same time, since the “first aerospace furnace” is a type of chemical processing equipment, safety issues related to its testing are given great attention by leaders at all levels. The leaders of the group company, the heads of relevant departments at the headquarters, and the leaders of the first institute have all maintained a high level of attention. For this project, everyone within the group company worked hard; many people personally took care of the growth of the \"first furnace in aerospace\". At the test site, all the astronauts and the employees of Puyang Longyu Chemical Company, which belongs to Henan Yongmei Group, shared the same feeling of looking forward to the moment of success. From October 8th to 13th, after more than 10 instances of the system shutting down automatically, the participants became anxious. They all stayed in the monitoring room, refusing to take a break. Many people worked non-stop for over 30 hours; when they got tired, they would connect two folding chairs together and lie down on them for a short rest. The thought of a successful test drive occupied the minds of everyone present; almost everyone was in a state of high tension. Someone joked, \"Everyone’s eyes were shining.\" ” The test run was once again interrupted by an automatic system shutdown. On-site technicians worked continuously for over 20 hours to identify the problem. Some advised those who had been working overtime continuously to take a break before continuing, but everyone sensed that success was near and refused to leave the testing room. Finally, at 11:15 on the 13th, the \"first furnace for spaceflight\" succeeded in loading coal in one attempt. The astronauts stood on the hillside, and when they saw the raging flames appear in their sight through the telescope, excited cheers burst from their throats at that very moment, rising toward the blue sky. “It worked! ”The control room also immediately became bustling; people cheered and applauded non-stop, making one call after another to share the good news. Crackling sounds of firecrackers could be heard in the courtyard of Puyang Longyu Chemical Company, belonging to Henan Yongmei Group... At 11:28, all parameters were normal. At 12:20, after two successful slag discharges, the system carried out the shutdown procedure as planned. For this test run, the test pressure was 1 MPa and the production load was 40%. The effective gas composition at the outlet of the gasifier reaches 87%, and the amount of by-product steam, as well as the temperatures of the coils and the gasifier shell, along with the condition of the slag, all meet the design requirements. The test run was **successful**. At 3 p.m. on October 15, the gasification furnace was completed of purging, its temperature was reduced to 40°C, and the scaffolding inside the furnace was installed. Technicians from Aerospace Coal Chemical Company and Puyang Longyu Chemical Company of Henan Yongmei Group entered the gasifier from the bottom of the furnace to inspect components such as the water wall and gasification nozzles. When they climbed out one by one, looking disheveled, from the \"belly\" of the gasifier, excited smiles appeared on their faces. Wang Mingkun could hardly contain his joy: \"There was localized slag accumulation on the water-cooled wall inside the furnace, and the gasification burner showed no signs of ablation or cracking.\" ” At 1 a.m. on October 16, the \"first furnace for spaceflight\" was successfully ignited once again; coal was added at 2:30 a.m., marking the start of 72 hours of continuous operation. At 7:10 p.m. on October 19, after confirming that all parameter indicators were within normal ranges throughout the operation phase, the entire set of equipment was shut down smoothly and safely as planned. “The first aerospace furnace achieved successful charging in one attempt, and the implementation phase has begun for large-scale aerospace furnaces capable of producing 350,000 to 400,000 tons of methanol per year. “The birth of China’s \"first space furnace\" signifies an further improvement in the industrialization capabilities of the aerospace technology application sector under the China Aerospace Science and Technology Corporation. Great success has been achieved in the use of aerospace technology in the coal chemical industry, and new progress has been made in establishing a new framework for the aerospace technology industry. Subsequently, the “first space furnace” will undergo nearly a month of system debugging before entering a phase of full-load, long-term production. As a demonstration project, the long-term stable operation of the “first aerospace furnace” still needs to be tested by time, but the aerospace professionals are full of confidence in achieving ultimate success.
I learned *a little more, which is great.
Hehehe, the original poster said it well! The furnace in Linquan of ours seems to be working properly as well.
Did it pass the performance assessment? Domestic technology is amazing; after all that time, Shell hasn’t succeeded, while aerospace has made rapid progress
Our factory is planning to install GSP gasification furnaces, and if we do so, we will definitely go with domestic ones – the patent fees for foreign ones are too high. . . . .
It has been over half a month since the 16th; what are the results of the operation? How was the 72-hour operation? Please give an overview
It’s very detailed; I finally have a systematic understanding of space furnaces.
Why is the test pressure so low? Is the operating pressure not high either?
