DZL Automatic Chain Grate Stoker Boiler

DZL Automatic Chain Grate Stoker Boiler

DZL series biomass fired boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. 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 boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The drum is welded assembly by cylinder and front back tube plate. This furnace structure in reasonable arrangement and high efficiency. This series boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.

This boiler could burn different kind biomass fuel, such as wood chips, rice husk, bagasse, peanut shell, cotton shell, coconut shell, etc. Biomass fuel is renewable green energy with a wide range of sources. Biomass energy will gradually replace coal and become one of the main energy sources. Compared with coal-fired boilers, biomass fuels have lower cost and lower operating cost.

PERFORMANCE ADVANTAGES


1. It uses arched tube plate and thread smokestacks constituted into the drum,the drum structure is quasi-elastic instead of quasi-rigid,abrogates the braced pieces of tube plate area, reduces the stress.The fire tube inside of tube plate is single return

2. The ascension pipes arranged at the bottom of drum,this make the sludge not easy to deposit,the high temperature zone of drum easy to be cooling,prevent the drum bottom swelling.

3. It adopts efficient heat transfer threaded pipe,strengthened heat transfer,then heating-up and pressure boost -up quickly, thus increasing the thermal efficiency.

4. Compact structure, smaller size compared with the same type, saving the boiler foundation cost.

5. Stable operation, easy to adjust, strong steam output.

6. Both wing wall and outlet widow inside of the furnace have the function of dust suppression,that make the original dust concentration controlled under the standard,thus ensuring the soot discharge scratch the index stipulated by the State Environmental

7. The Unique double secondary air design improved the ignition conditions of biomass fuel, adopt the independent wind chamber to achieve the reasonable ventilation, and from a air dynamic field which is beneficial to burn in the chamber, achieve high com
