Apr 23, 2016 · Fire Tube Boiler It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar and that’s why they fall under the category of low pressure boilers.
Water tube boiler refers to the boiler that water, steam or the steam-water mixture flows in the tubes, and fire or the smoke are combustion and flow outside the flues. Compared with fire tube boiler, water tube boiler has no limitation on steam capacity and pressure, so it is fit for the user who need large capacity.

Vertical Coal/Wood Fired Boiler (200-2000kg/hr) LSG/LSH series coal or biomass steam boiler is vertical type structure with small steam capacity. The combustion equipment is moving grate. The boiler uses the general combustion technique. Coal or biomass fuel is fed by workers manually.
Spreader Stoker Boiler Spreader stokers utilize a combination of suspension burning and grate burning. The coal is continually fed into the furnace above a burning bed of coal. The coal fines are burned in suspension; the larger particles fall to the grate, where they are burned in a thin, fastburning coal bed.
Alibaba.com offers 9,680 coal fired water tube boiler products. About 99% of these are boilers, 1% are boiler parts, and 1% are other food processing machinery. A wide variety of coal fired water tube boiler options are available to you, such as oil-fired, coal-fired, and gas-fired.
Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This coal fired stoker boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode.
Fire tube boilers usually have a capacity of below 20t/h, while water tube ones of 20t/h or more as capacity expansion is possible. The three series are designed with large furnaces, the thermal efficiency is over 98%, and the NOx emissions are as low as 30mg/Nm3.
As the coal is burned on a grate or in suspension above the grate, heat is released and transferred to water-filled boiler tubes by radiation and convection. Combustion air below and above the grate is ad- justed by the use of dampers to achieve optimum combustion and to minimize smoke generation.
It needs to be around 250 to 300 gallons for each 100,000 BTUh maximum fire output of the boiler, and should have its own circulator -- possibly with a high limit aquastat on the boiler (circulator on at 190). The tank itself need not be pressurized; you can use a heat exchanger such as might be found in an indirect hot water tank.
