China Tobacco Shiweice(Yunnan) Reconstituted Tobacco Co., Ltd. mainly targets the Chinese cigarette market. Due to the need of production development, China Tobacco Shiweice adopts the most advanced papermaking method to reconstitute the tobacco leaf production process. Remanufactured tobacco needs a large amount of steam in production. The previous boiler's supply can not meet the demand for new production processes. After the natural gas direct supply pipeline project was completed, China Tobacco Shiweize ordered a 20 tph gas-fired steam boiler with natural gas as fuel from ZOZEN boiler through a bidding activity. The body and hearth of the series boilers are surrounded by membrane-type water-cooled walls, and use micro-positive pressure combustion, there is no cross-talk problem, the operating environment is without pollution.
ZOZEN boiler's steam boiler adopts natural water circulation circuit, and the water circulating flow resistance is small, so that there is no phenomenon such as stagnation, reverse flow, and free liquid surface deterioration of the water cycle, which can effectively prevent the occurrence of tube-burst accident.
