20 ton coal fired fluid bed boiler biomass power plant
- DZL boiler is durable and Long life time (more than 10years).
- Enough steam output, less heat dissipation, high thermal efficiency.lowest fuel consumption, lower power consumption.
- with 95% high efficiency dust collector, more Eco-friendly.
- Full automatic control, Protection devices for overheating, overpressure, lacking water, leak detection, flameout
- The featured structure of the boiler: Threaded pipe, Airfoil flue , Convex tube plate , The backwater towards hightemperature tube plate, Simple loop circuit, Dust separated chamber, big furnace, compact structure so on.
1,Horizontal ,3 pass and large furnace
Ensure the sufficient combustion.
The large diameter boiler increase the heating surface to ensure the high thermal efficiency.
2,The spirally corrugated tube
Strength the heat transfer and improve the thermal efficiency .The smoke in the tube has the distribution effect,the dust not easy to deposit ,the tube can cleat by itself.
3,High temperature resistance refractory brick
The furnace wall is poured by the heat resistance concrete and high temperature resistance refractory brick,decrease heat loss,increase the boiler thermal efficiency.
4,The economizer
Made of ND corrosion resistance steel,make full use of gas heat .reduce the exhaust temperature improve thermal efficiency.
