DZH Hand-Fired Biomass Boiler Introduction

DZH hand-fired biomass boiler is a single-pot vertical biomass boiler

Our boilers are arranged in a horizontal three-way fire-water tube arrangement, the new furnace design maximum extent to promote fuel combustion so that the thermal efficiency of 88%.

After fuel combustion, the flue gas is treated by the economizer, air preheater, and other equipment, then enter the dust collector. 

Finally, the flue gas is discharged into the atmosphere by the chimney. The remaining small amount of ash residue falls into the slag outlet and can be used as fertilizer for crop growth.

Yongxing boiler can use crop processing biomass particles such as straw, sawdust, peanut shell as fuel. Compared with ordinary coal-fired boilers, waste gas emissions are significantly reduced.


Meanwhile, our boiler has the advantages of high automation level, safe and stable operation, perfect protection function, and so on. It is a wise choice to buy our boiler.
