Biomass Fired Boiler Burning process
The fuel falls from the coal hopper to the front of the grate. With the operation of the grate, the coal undergoes preheating, dry distillation, ignition, and embers. The slag falls into the slag hopper and is discharged from the furnace at any time by the slag remover. The flue gas is in the front and back arches. The throat between the throat can form a vortex to fully mix with the air, heat the front arch, improve the fire conditions, enter the two-wing convection tube bundle through the exit smoke window on the upper part of the arch, enter the threaded smoke pipe through the front smoke box, and pass through the economizer and dust collector. The induced draft fan is led to the chimney and discharged.

This coal fired boiler is single drum horizontal type shell boiler, the combustion equipment is chain grate, has the advantages of feed mechanically and strong adaptability of different fuels.
The DZL series quickly installed coal fired steam boiler is the most advanced water-fire tube boiler in Chinese market, This series boiler can be used in textile, food and package factory with high efficiency, small in size and long working life.

The coal fired steam boiler after improvement takes use of structure of wing type smoke duct, one-way screwed smoke tube, arched tube plate, smoke and gas separate room and several other advanced technology, which has increased the water circulation speed and safety factor. This boiler series is well designed, compactly made up, quickly installed, mono layer, so that the civil engineering and investment could be saved. With these improvement, the boiler's working life extend much to be the national energy saving product.

1-6T steam boiler usally transported as entiraty part, Capacity more than 8t(including 8 t/h)are transported as up body and bottom body (chain grate) .

Boiler fuel can be applied to coal, biomass particles, sawdust, palm shell, straw and other fuels; At the same time, relevant structures shall be reasonably designed according to different fuel characteristics to ensure efficient, energy-saving and stable operation of the boiler.
