A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
ABOUT US. Zhengzhou Boiler CO., LTD.found in 1945, as industrial boiler manufacturer. we mainly supply Coal fired boiler, Biomass fired boiler, CFB boiler, Waste heat recovery boiler, Power plant boiler.
Use coal or biomass as the boiler fuel to get high temperature steam, hot water or hot oil. Coal/Biomass fired steam boiler, capacity from 100kg/h to 75Ton/h; Coal/Biomass fired hot water boiler, capacity from 350kw to 21MW; Coal/Biomass fired thermal oil boiler, capacity from 15x104Kcal/h to 1400x104Kcal/h.
Fire Tube Boiler Construction and Working Principle of Fire Tube Boiler. The construction of a water tube boiler can be equipped with cylindrical shell, vertical, firebox in the base, space for water in the center segment, and space for steam in the higher segment.
Stoker Fired Boiler are classified according to the method of feeding fuel to the furnace and by the type of grate. The main types of stokers are: Chain-grate or travelling-grate stoker Spreader stoker boiler Travelling Grate or chain grate Stoker Boiler In Travelling Grate boiler coal is fed at one end of a moving steel …
To improve Boiler efficiency, coal must burn out. Incomplete combustion in mark with still remaining coal combustion on the back of the furnace.
