The first multi-nozzle opposed coal-water slurry gasifier was put into operation

<

China's first new multi-nozzle opposed-type coal-water slurry gasifier, which is independently developed and constructed by China's scientific and technological personnel and has 10 independent intellectual property rights and pressured to create the world's first coal gasification technology, is currently in Cathay Pacific, a subsidiary of Shandong Yinzhou Mining Group. The chemical company was put into production, which ended the history of China's introduction of foreign coal gasification technology. Recently, this new technology passed the expert appraisal.

Compared with the similar foreign technology introduced, this new gasifier has doubled the adjustable range of gasifier load, low oxygen consumption, high comprehensive utilization rate of coal, and more pure raw materials such as carbon monoxide and hydrogen. The gas produced during the production of methanol is directly generated. What is more valuable is that it has a wide range of applications for coal, especially for high-sulfur coal that consumes low ash melting point. High-sulfur coal is banned from use in all boilers because it emits a large amount of harmful gases and pollutes the air. The high-sulfur coal burned by this new technology basically does not generate harmful gases under high-temperature reaction, and produces by-products by desulfurization, which is called “total thawing of high-sulfur coal” by the technical community.

Coal chemical industry continuously feeds under high pressure, and has always been called the “forbidden zone” for safe production. Guotai Chemical Company has solved and solved more than 30 technical problems through repeated trials such as feeding under low and medium pressure conditions, and has embarked on a new way of safe production with pressure and pressure under high pressure, thus creating the world's coal gasification technology. The first.
