Introduction
DZL SZL coal boiler, also named chain grate boiler, automatic coal boiler, provide steam, hot water or central heating for factory, company.
Certified by ASME CE ISO DOSH EAC TUV BUV, new furnace design adapted to coal fuel, and ash remove tech, to ensure customer's boiler in good operation and long lifetime. 
● Automatic water tube & fire tube boiler
● Boiler capacity from 0.5ton to 40ton, 350kw to 28.000kw
● 3 pass wet-back structure, larger furnace, unique expansion welding
● Low emission and excellent operating performance
● Customized combustion device and furnace according to the fuel characteristics. (can use coal, biomass pellet, wood chips, rice husk, palm kernel shell, other fruit shells and so on)
1. 3-pass wet back, arched tube plate and spiral corrugated fire tubes, to strengthen boiler efficiency;
2. Two-Wing flue gas at side, reduce smoke temperature, reduce heat load of boiler bottom;
3. PLC digital control, interlock system for fuel feeding, water treatment, combustion furnace, fan;
4. Built-in steam separator, ensure high steam quality with wetness below 1%
5. Five stages water level check, four stages pressure protection, over smoke gas temperature;
6. Built-in rotary sootblower and inspection door
7. Dust separation chamber, higher efficiency, reduce the original dust
8. Equipped economizer/preheater/cyclon/wet scrubber, environmental protection and energy conservation
