A speech that came in second to last place

Kisses to my baby, hello everyone! The topic of my speech today is “Kiss My Baby”. When it comes to gas production, it might give people the impression of being \"clumsy,\" \"dangerous,\" and \"dirty.\" Indeed, gas generators made of steel are more durable, giving them a bulky appearance ； Flammable gas in a closed container, when it reaches its explosive limit, will explode upon contact with fire ； What we use are “black tangyuan” made by binding anthracite powder together. But as a furnace operator with many years of experience, I prefer to view gas generators as children, because there are so many similarities between them. As long as you pay close attention to her and take good care of her in your daily work, and understand her temperament, she will obediently produce high-quality gas for us on a steady basis. Let’s first introduce our child to everyone. The coal feeding system, which consists of hoists, belts, upper and lower drums, etc., is the mouth of the generating furnace; it is the mechanism through which the furnace receives the ‘black balls’. The furnace chamber is the core of the producer; it is here that the coal balls undergo processes of dry distillation, drying, reduction, and oxidation as part of a \"digestive absorption\" process, which transforms the energy contained in the coal into gas. The grate is the heart of the generator; it is responsible for distributing air and breaking up slag. Any damage or defect to it can harm the health of the generator. The ash removal device, which consists of a small gray knife, a large gray knife, a gray tray, etc., functions like the intestines of a producer furnace; ensuring the smooth functioning of these \"intestines\" is a necessary condition for maintaining good health. The bottom saturation blast system is the mechanism through which we supply ‘water’ to the generator; it can only handle dry materials – children wouldn’t be able to tolerate that. The process of producing mixed generator gas requires that our gasifying agent be a mixed gas to which steam has been added. The water seal at the bottom of the furnace acts as a safety barrier for the blast furnace; the volatile gas requires a safe area in which to exist, as it is dangerous if it spreads around freely. “\"Diseases enter through the mouth,\" so ensuring the quality of coal balls is the first thing we should do. “\"Black tangyuan\" has 13 indicators such as moisture, volatile matter, and ash content. (Fixed carbon content, sulfur content, ash fusion point, calorific value, cold compressive strength, hot strength, water immersion strength, re-drying strength, drop strength, thermal stability) are all of practical significance. For example, coal balls with too high an ash content and low carbon levels are considered nutrient-poor coarse grains; blast furnaces tend to consume larger amounts of such coal. Over time, this can lead to problems with the ash removal system ； Briquettes with poor thermal stability are considered to be grain contaminated with pathogens; consuming them can cause diarrhea. They also spread out in the fire layer, affecting air distribution ； Coal balls with poor mechanical strength are like tough wild vegetables that are difficult to swallow; eating them can cause nausea, and they may drift out through the exhaust pipe, affecting the operation of the pipes in the rear section. Every “child” has its own characteristics; take our large 3.2-meter blast furnace as an example. After production began at the end of 2007, since we didn’t understand her behavior patterns, she kept eating a lot and producing a lot of waste; the gas output per ton of coal was less than 3000 m3/h, and the calorific value of the gas ranged around 5000 kj/Nm3. All this also left us uncles and brothers exhausted, with back and leg pains. To this end, we formed a \"task force\" to diagnose and address the issues of the 3.2-meter gas generator. Too much fine coal powder entering the furnace can cause localized sparking, which indicates that the \"teeth\" are not in good condition; we will then replace them with better ones and lengthen the sieve plate. The grates tend to crack, so we changed the material to cast steel, improved the precision of the base’s fit, thereby making the \"heart\" stronger and more robust. If the dregs are black, it indicates that the intestines need to be cleaned; we then make the small gray knives of varying lengths equal in length and evenly distributed. After partial modification and treatment, the 3.2-meter producer furnace has become a high-performance unit with low energy consumption, and it has now become the main furnace in the gas production process. The residual carbon in the ash decreased significantly, and the calorific value of the gas increased by nearly 500 kj/Nm3. Our “Excellence QC Team” was also selected as an outstanding QC team in Sichuan Province for 2009. (The certificate has not been received yet.) Children need to be taken good care of, and it is the responsibility of the furnace operator to ensure that it operates stably in its optimal condition, by following the operational requirements and taking into account the specific conditions of the furnace. Timed brazing testing is a direct method for monitoring the furnace conditions, allowing for an intuitive understanding of the temperature and thickness of each gasification reaction layer. The temperature of the fire zone drill core, which is “dark red–deep red”, ranges from 1000 to 1150°C, indicating a normal condition ； “The \"deep red–bright red\" temperature range of 1150–1250°C is also considered normal, but it is necessary to prevent it from rising any further, as higher temperatures could lead to the reaching of the ash melting point and subsequent coking. If the temperature of the fire layer is too low, it can lead to incomplete reactions, black slag formation, and a decrease in the calorific value of the gas ； If the temperature of the fire layer is too high, it can lead to slag formation and spattering, making it difficult to maintain stable furnace conditions ； The varying lengths of the fire layers in different areas indicate a tendency toward uneven furnace distribution. By adjusting the saturation temperature, slag removal, coal feeding, and coal distribution in a timely manner based on the probe readings, it is possible to control the state of the gasification reaction. An overly thick material layer can lead to uneven air distribution ； An excessively thin material layer will result in a shorter dry distillation layer, affecting the calorific value of the gas and increasing the risk of ignition. Therefore, the thickness of the material layer and the empty layer also needs to be kept within a certain range. Blast furnaces can sometimes develop minor problems for various reasons, which requires the personnel working in the furnace area to work together and take careful care of them. The three days after each furnace startup are a sensitive period when problems are likely to occur. “Staying vigilant in monitoring the fire, frequently checking the probes, as well as adding or removing materials more often – all these require us to put in more effort than usual. Once, after starting the furnace, there was an excessive amount of ash and pulverized coal in the furnace slag, which accumulated in the ash tray and could not be removed. The boiler operators rushed to the factory overnight and used fire hoses to wash away the ash in the ash trays. Ignoring their soaked clothes and fatigue, they continued working until after 3 a.m., not returning home until production was back to normal. On the afternoon of September 9th, it was my shift, and a customer complained that the calorific value of the gas was insufficient. After checking the furnace with a testing probe, I found that everything was normal. It then occurred to me that we were using \"processed coal\" that contained a high amount of ash, which would reduce the efficiency of the reaction; in our jargon, this means the performance is \"very poor\". By lowering the saturation temperature and adjusting the ash removal and coal feeding amounts, the fire layer is thickened appropriately as well as the material layer, and thus the calorific value of the gas gradually increases. Once a certain component fails suddenly, and the production setup does not allow the furnace to be shut down immediately, our workload increases dramatically – we have to take turns removing slag and adjusting the coal, sweat quickly soaks through our clothes, and the steel rods in our hands become much heavier than usual. Gas production is a type of specialized work. Production experience teaches us that \"stability is the foundation of efficiency.\" Once certain skills have been acquired, by applying careful attention and effort in operation, our gas generators will become reliable, safe, and efficient. Finally, please allow me to say proudly, on behalf of all the employees in our gas production process and all members of the QC team: \"The gas generators in our possession are capable of producing high-quality gas in a stable and efficient manner.\" ”“Kiss my darling, I’m going to fly high. . . . . . ”Thank you all!
