Boiler Introduction

DZL series coal fired steam boilers are designed as single-drum boilers with fire tubes and water tubes. They have fast heat conduction, fast steam pressure rise, strong adaptability to biomass fuel, compact structure and high thermal efficiency. this series of steam boilers adopt the latest science and technology in the industry such as arched tube plate and threaded flue smoke pipes, which effectively improves the overall efficiency of the boiler and prevents the occurrence of faults such as grate coking and tube plate leakage.

Boiler Advantage
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.

-automatic fuel feeding duel to chain grate design;

-high efficiency due to big heating surface and grate area;

-low emission,friendly to environment;

-wide fuel adaptability, applicable for wood pellet, coal, palm nuts, etc;

-intelligent boiler controller with PLC and touch screen, easy for operation and parameters setting;

-good looking & long life span;

4.What is the height of chimney?

the chimney is usually 30m, irrespective of the special circumstances.


5.What are the heat-resistance temperature of grate and furnace?

the heat resistance temperature of grate is related to the grate material, the highest temperature could be as high as 1100℃, and the lower temperature could be 700℃.


6.What is the temperature of smoke gas?

the highest temperature of smoke gas is 165℃. long can the coal/biomass fired boiler works?

Coal/biomass boilers could work for 10~15 years, under correct operation, high water and coal quality, etc. to avoid collapse of bricks, and what should be done if it happened?

When boiler installation finished, drying the boiler according to the manual, it's very important to avoid collapse of bricks. many stokers do I need for one boiler?
