Chongqing Changshou District plans to incubate a “heavy chemical industry city†with a production value of 500 billion yuan in five years. This afternoon, the reporter learned from the Chongqing Changshou District Government that during the “Twelfth Five-Year Plan†period, the district will use the economic and technological development zone as the core platform, relying on five major industrial clusters of chemical industry, steel, new materials, equipment manufacturing, and electronic information to create capacity. 500 billion class heavy chemical special development zone. Among them, the construction of a world-class natural gas chemical base is particularly attracting attention. It is understood that by 2015, the district will form more than 10 billion industrial clusters. In building a world-class natural gas chemical industry base, taking acetylene from natural gas as a leader, the development of “firepower†will focus on projects such as acetylene, methanol, acetic acid, BDO, MTO, and PVB. At that time, a 50 billion yuan natural gas chemical industrial cluster will be formed. In addition, in petrochemicals, coal chemical industry, and iron and steel metallurgy, 5 billion yuan, 20 billion yuan, and 80 billion yuan will be formed in industrial clusters five years later. According to the government of Changshou District, in the “2+3†industrial system in the region, in addition to the two major industries of chemical industry and steel industry, the three emerging industries of new materials, equipment manufacturing, and electronic information are the industrial highlands of the city and the region. Part of Western Heavy Chemical Industry Base. It is reported that five years later, in these three emerging industries and other industries, several industrial clusters with a size of over RMB 10 billion will be formed.

Boiler Steam header is the main supporting equipment of the boiler to distribute the steam generated by the boiler operation to various pipelines, it also serves as a reservoir that feeds steam to the individual heating circuits. The boiler steam header must be large enough to virtually eliminate pressure drop between the boiler and the beginning of the circuit.
