ZOZEN launches more high-efficiency and eco-friendly DZL series tri-drum biomass-fired boiler
Through scientifically arranging the furnace arch, furnace wall, furnace heating surface and secondary air, the second generation of ZOZEN biomass-fired boilers have solved the common problems of traditional biomass-fired boilers. In order to further solve the ash accumulation problem in the convention area of the second generation of ZOZEN biomass-fired boilers with double drums, ZOZEN has cooperated with the Department of Thermal Engineering of Shanghai Jiaotong University to jointly develop the DZL series tri-drum biomass-fired boiler.

The advantages of ZOZEN DZL series tri-drum biomass-fired boiler
Wide fuel adaptability, high thermal efficiency
According to different biomass fuel characteristics, the boiler can be equipped with different grates to ensure the sufficient combustion of biomass fuels.
The furnace height is increased by 1-3 meters, which can solve the coking problem of furnace wall and meet the combustion requirements for raw biomass materials.
The dead angle of the flue gas scouring the heating surface is small, so it is not easy to form a vortex, thus the heating surface has higher heat transfer efficiency.
Good environmental protection performance
The boiler has the flue gas denitrification system with ammonia-gas spraying device, so the NOx emission is less than 200mg/m³.
No need to stop the boiler to clean the dust because there is less dust accumulation on the heating surface, which can make the boiler operate normally for a longer time.
The dust produced by burning biomass fuel is easily discharged into the ash hopper, which reduces the burden of dust collector and is more eco-friendly under the same conditions.
Less ash accumulation
The flue gas enters the convention area from furnace outlet, and the dust in the flue gas directly falls into the ash hopper at the bottom of convention area. Through the rotary dust discharge valve and tube, the accumulated ash is discharged onto the grate to realize the real-time dust removal, which solves the ash accumulation problem in the convention area of biomass-fired boiler from the perspective of structure.
