Overview
The Introduction of Coal Steam Boiler:
Yuanda Coal steam boiler have two types.
One is DZH hand operate moving grate type which is a manual type coal/biomass boiler needs labour to feed fuel and remove the dregs. It has Fire tube and water tube structure and suitable for small capacity, less than 8ton, and the equipment investment is low. The fuel can be wood log, wood chip, wood waste, coal and other solid fuel, etc. And the boiler is nude-packing, accessories are packed with wooden box for protection.
Another is DZL chain grate stoker automatic feeding fuel and removing dregs type which is a horizontal three-return water-fire pipe chain grate boiler, burning medium-sized bituminous coal. The boiler body is arranged vertically in a single drum. The threaded pyrotechnic tube is arranged in the drum to form a convection heating surface. The drum and the water wall on both sides form a furnace heating surface, and the burning equipment adopts a light chain grate; the overall quick installation form is delivered. Electrical control realizes stepless speed regulation of the grate, limit parameter alarm and chain protection.

Yuanda Boiler, Chinese famous brand with Grade-A license. Not only popular in china but also exported to 80+ countries with 60+ years experience, especially our coal steam boiler is highly praised by customers.
Our Coal/Biomass steam boiler widely used in food&beverage processing, medicine industry, chemical industry, textile mill, garment industry, wood processing, etc.
The Running Site of Coal Steam Boiler:
The Advantages of DZL Coal Steam Boiler:
1. More than 60 years of technical experience, 0 accident;
2. The new furnace arch strengthens combustion, and the coal type has strong adaptability; the boiler has sufficient output, fast heating and the thermal efficiency reaches more than 85%;
3. The threaded pipe strengthens the heat transfer, the airfoil flue is arranged reasonably, and the convex tube plate prevents cracking;
4. Professional steam-water separation device, high steam quality;
5. Inertial separation of soot, low concentration of original dust, environmental protection and energy saving;
6. The unique backwater injection technology of the hot water boiler prevents the tube from bursting and the water circulation is more reliable;
7. Fast-loading, assembly, semi-assembly and delivery, transportation, installation cycle and cost reduction of more than 30%;
8. Data collection, analysis, storage and remote monitoring of the Internet.
