Coal Fired Boiler

Yuanda has DZL single-drum water-fire tube coal boiler and SZL double-drum water-tube coal boiler. Can produce steam or hot water for factory production, or building/central heating.

Both boilers combustion equipment is chain grate (small flake type is optional). With advantages of mechanized automatic feeding, strong fuel adaptability, steady running, less coal leakage, and easy maintenance.

Reliable high quality, Passed ASME CE ISO DOSH EAC certification.

"DZL" Coal Boiler

DZL coal boiler meaning single drum chain grate boiler, use water tube & fire tube structure, lower water quality requirements.

Features:

1. It adopts horizontal packaged design(The furnace and chain grate are packaged before delivery), which have less installation.

2. Spirally corrugated fire tubes, improves thermal efficiency, reduces flue gas temperature.

3. Wing-shape flue, allows smoke to enter the front smoke box smoothly, prevents tube sheet damage.

4. Hot water boilers adopts the unique backwater injection technology.

"SZL"Coal Boiler

SZL coal boiler meaning double drum chain grate boiler, use water tube membrane wall structure. High water quality requirements.

Features:

1. 1-6ton adopts horizontal packaged design. 6-50ton usually delivered in bulk(The furnace and chain grate will assembled at user site), which requires more installation work.

3. Whirlwind burning chamber structure.

4. Front-rear water-cooled arch design.

5. Independent wind chamber.

Advantages

1. 3-pass wet back sructure, arched tube plate, to strengthen boiler efficiency;

2. New furnace arch with upside down "α" flue gas flow;

3. Equipped economizer/preheater/cyclon/wet scrubber, environmental protection and energy conservation;

4. Built-in steam separator, ensure high steam quality with wetness below 1%;

5. Five stages safety features like water level, pressure and temperature monitoring etc;

6. Built-in dust cleaning system, and inspection door;

7. Dust separation chamber, higher efficiency, reduce the original dust;
