Generally speaking, the industrial boiler falls into two broad categories: fire tube boiler and water tube boiler. In pulp & paper industry, industrial boiler is needed. And the plant chooses a boiler product based on the plant scale and need.
Fire tube boiler VS water tube boiler
Fire Tube Boilers –the WNS gas oil boiler is a typical type of fire tube boiler. Fire tube boilers utilize a system of tubes through which the heat source, or “fire” passes. The tubes are surrounded by water and the water is heated as the tubes also rise in temperature. Eventually steam is released for use.
Water Tube Boilers – In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam. Water tube boiler is very common, such as SZL series chain grate boiler, waste heat boiler, large capacity CFB boiler.
Biomass fired boiler for paper mill
In paper mill, wood is one of the main raw materials. To fully utilize the wood saw dust, wood chips, a biomass boiler can be selected for its production. The SZL series biomass steam boiler is double-drum, chain grate type water tube boiler, and it is usually used in middle and small size paper mill. High efficiency, clean combustion, it can not only reuse the wastes during processing, also save cost for factory.
Paper & pulp plant boiler manufacturer
Not only biomass fired boiler is used in the plant, a waste heat recovery boiler is also common in large paper mills. if you want to purchase a boiler for your plant, leave us your requirement and we can recommend you a best program!
