Domestic gasifiers set a new record for stability

At 11 o'clock on the morning of November 5th, the reporter saw employees working in an orderly manner in front of the central control room console of the water-wall coal-water slurry gasifier of Shanxi Yangxi Coal Fengxi Linfen Branch. From time to time, voices of internal and external conversations are heard from intercoms or phones. Chief Operating Officer Liu Yanan pointed to the number "74" on the center console display and excitedly told the reporter: "At this moment, the chemical feed of the water-wall coal-water slurry gasifier has been fully loaded, continuous and stable for a full 74 days. !”

The picture shows the chief engineer Xie Pingping (second from left) interviewed by a reporter at the site of the water-wall gasifier.

Liu Yanan went on to say: “The continuous and stable operation for 74 days means that we have created a historical record for the continuous operation of China’s coal gasifiers that have completely independent intellectual property rights and are fully domestically produced materials; this means that China has mastered advanced coal gasification. Technology means that it already has the foundation for industrialization and rapid promotion.” He told reporters that coal gasification technology is a complex process of system integration of many advanced technologies. It involves not only process technology but also engineering technology. Many problems need to be practiced. Fully exposed. Before such a long-running test proves to be fully mature, industrialization promotion will bring great risks. ”
The reporter and Liu Yanan talked together. “Is the operating condition always stable?” “Very good. This gasifier has advanced technology and major technical indicators in the international advanced level, but there is no relevant operating experience in China, and it is very difficult. When the device enters continuous operation After the state, the technical problems of smooth driving followed one after another. After a series of explorations, we have now basically mastered the automatic control technology of the water-wall coal-water slurry gasifier, and the 2800 water-wall coal-water slurry gasifier is currently in operation. Handling 750 tons of coal, raw material consumption and gas production have all reached the design requirements." Liu Yanan said with confidence.
From the main control room, the chief engineer dismissed the device that was tens of meters in height and told reporters that this was the result of their joint venture with Tsinghua University and Beijing D&C to form a technological innovation and alliance. The first set of large-scale industrialized demonstration devices for water-wall coal-water slurry gasification.
“The operation of the coal-water slurry gasifier in Linyi Chemicals has proved that the Chinese have greatly exceeded the technology of coal-water-slurry gasification in foreign countries. Only if we are successful in one feed!” Zhang Jieping couldn't help raising his thumb.
"In a short span of 74 days, coal-water slurry water-wall gasifiers have caused repercussions in China. There are dozens of companies that have come to visit and consult the operation conditions of the furnaces. We and PetroChina Karamay Petrochemical hydrogen supply, Zhumadian luxury horses, Guangdong Yudean Group IGCG, Henan Lianxinxin No. 4 Plant Technical Transformation, Yangmei Coal Group Taihuan Transformation and Development Project have signed contracts or reached cooperation intentions.” Standing in the side of the Deputy General Manager of Lincang Branch Wu Huicang could not hide Excitement.
Wu Cuncang went on to say: “This set of equipment gasification technology is mature, operation is safe and reliable, there is no emission of waste gas in the production, and it is easy to realize the localization of gasification coal. The total investment of water wall gasifier is 112 million yuan, which is relative to other domestic operations. Gasification technology, investment savings of 30% to 50%, and 100% localization of the device. Therefore, the water-wall gasification technology has surpassed foreign countries in all respects and it is of great significance."
Wu Cangcang also told reporters: “Nationalities are the world’s. The country should directly reduce or exempt taxes on domestically-developed coal gasifier processing and manufacturing equipment and gasifier products, and should formulate policies to encourage the promotion of domestic gasifiers. Enterprises using domestic coal gasifiers will be encouraged by investment subsidies, tax relief, and other policies to create a better policy environment for domestic coal gasifiers."
At the end of the interview, in the face of the tall production plant group pipeline, the “Successful R&D of the water-wall gasifier plant, which made our company stand on the cutting edge of the coal gasification technology” slogan, imagining that there was a galloping in the steel pipeline. The chemical materials, the reporter's heart was also shocked.

Welding Fume Extractor

Welding fume extractor is a kind of industrial environmental protection equipment, which is mainly used in arc welding, CO2 protection welding, MAG protection welding, special welding, cutting and polishing place.The purified air can be directly discharged indoors. It can absorb and treat the waste slag, toxic gas, and harmful gases generated during welding, such as electric welding, protective welding and argon arc welding, by means of filtration and purification. The welding smoke extractor can prevent gas pollution, reduce the effects of harmful substances on the working people, and prevent occupational diseases, mainly electric welding pneumoconiosis
