China Drying Network News China's first self-owned intellectual property rights large dry powder pressure gasification furnace (WHG furnace) has been officially shipped in recent days through expert inspection. The set of coal gasification furnaces for the first time achieved internal parts and shells that were simultaneously developed by China. The functional equivalents of the same type of gasifiers used in the coal chemical industry in the United States have achieved a carbon conversion rate of 99%, but the cost has been significantly reduced. The first set of WHG furnaces used for this delivery further promoted the localization of large-scale gasification plants and provided technical support with complete independent intellectual property rights for the development of China's coal chemical industry, reaching the international advanced level.
It is understood that this WHG furnace was independently developed by China Wuhuan Engineering Co., Ltd., under the jurisdiction of Sichuan Bluestar Machinery Co., Ltd. (hereinafter referred to as Bluestar Machinery) of the China Chemical Industry Group, and currently represents the high-end level of China's coal gasification equipment. The daily investment of 1,300 tons of coal is planned to be put into operation in a coal chemical project of a Henan enterprise.
“In the past, similar products mostly depended on imports, and manufacturing was difficult. The most important link was internal parts and shell manufacturing, especially internal parts, and the structure was complex. The manufacturing and assembly precision requirements were extremely high.†The relevant person in charge of Lanxing Machinery said, “Imported products There are defects such as large investment and poor continuous operation. Compared with similar foreign products, the WHG furnace has undergone major technological innovations and obtained a number of patents. The chilling process of the gasification unit has the advantages of wide adaptability of coal types, non-cohesive coal ash, stable operation, and low investment.
In recent years, due to the energy pattern of “oil shortage, low gas, and rich coal†in China, the new coal chemical industry has become popular. It converts low-cost coal into synthesis gas and is widely used in the production of methanol, acetic acid, and fertilizers. Gas conversion cost savings of 30 to 40%. According to the above sources, the core of coal chemical industry is gasification technology and equipment. In the early years, such devices were basically monopolized by foreign companies, and domestic coal chemical companies had to spend huge sums to buy. Since the country promoted independent innovation, the coal gasifier also has domestic representative products such as four-nozzle furnaces and aerospace furnaces. As the largest mechanical manufacturing plant in Southwest China, Lanxing Machinery also developed a pulverized coal pressurized gasification device as early as 2006. , It has been operating for more than 6 years since it was put into operation.
