Rubber can be seen everywhere in life. There are more and more rubber products in the industrial sector. There are many varieties and wide applications. The main products are tapes, hoses, gaskets, rubber rollers, rubber sheets and rubber linings. Labor protection products. For rubber plants, boilers are a very important configuration. Rubber companies use steam generated by steam boilers. The rubber article can be vulcanized by a vulcanization apparatus to change the rubber article into an elastomer. Customers should choose the right boiler according to their own needs.

Necessity textile mill converted to a coal-fired analysis of the thermal efficiency of coal fired boiler gas boiler is a boiler equipment industry needs is more important, because a lot of links to the papermaking process requires a lot of steam drying, stereotypes and so on. However, along with the national policy of environmental protection departments to ban coal-fired boilers, and now more and more manufacturers have to use coal-fired boilers to coal-fired boilers upgrading or purchasing a new low - NOx emissions. Mills from coal to gas boilers is an important direction of the current transformation of coal-fired boilers, is one of more types of enterprise transformation, especially in the area more natural gas, coal into gas boiler is the main way. 1, in order to transform mechanization layered fired boiler gas boiler, you should first remove the front arch and a rear arch, while increasing the bottom heating surface, instead grate, grate to prevent overheating, combustion; 2, through the furnace heat transfer calculation methods determining the size of the boiler, furnace flame center position, and then pouring furnace work. In order to avoid the center position after arch boiler tubes, based on the original slope of the original arch made pipe. 3, the furnace in order to prevent an explosion, when the coal-fired boiler furnace gas is substituted, or when fuel not atomized combustion gases in the furnace incomplete combustion or heating surface of the end of the furnace, a fire or explosion occurs, should be mounting the appropriate parts of the boiler explosion vent, and to increase the ignition and flame failure protection program control to automatic control means, to ensure safe operation of the boiler. 4, is closely related to the selection and arrangement of the burner and furnace, the filling degree of the flame in the furnace should preferably not to form a dead air. Gas burner arrangement considered reasonable and piping layout, convenient operation, inspection and maintenance;

Unlike conventional pulverized coal (PC) technology, CFBs allow for the use of lower calorie coal - 4,000 kcal/kg compared to 6,000 kcal/kg typically used in a power plant coal fuel CFB analysis of the thermal efficiency of coal fired boiler - plus five percent biomass (woodchips), therefore helping reduce fuel costs and widen its procurement possibilities, without requiring add-on flue gas desulfurization equipment.
