Automatic Moving Grate Coal Fired Steam Boiler is horizontal single-drum shell boiler with water-fire tubes. It has chain grate as burning device, upper-in-and-upper-out style natural water circulation with ejection for hot water boiler of this series, the right and left side of furnace as radiant heating surface, two wings of furnace and threaded smoke tubes as convection heating surface and three-dimensional shield shell. Furnace is divided by Smoke baffle wall into combustion chamber (firebox) at front and reburning chamber at back.

Performance Features

Boiler Feature

1. Reasonable heat surface and burning device, heat efficiency is 4%～5% higher than national standard.

2. Reasonable flue gas speed, heating surface without ash deposition and no abrasion, under the condition of no soot-blowing, the boiler can work full-load, high-efficiency and safety in long term.

3. The big and tall boiler furnace can be designed according to the different fuel to improve the burning rate of fuel and remove black smoke.

4. All independent loop and reasonable coal boiler injected circulation are specially designed and adopted for the hot water boilers. The medium speed in loop of heat surface is higher than national standard

5. 1-20T/H & 0.7-14MW boiler adopt big and high strength grate, add rolling device improves the boilers’ safety, lessen coal leakage and adjust burning conveniently.

6. Over 20T/H & 14MW boiler adopt flake type or beam type chain grate, less coal leakage, convenient burning adjustment. Closed soot cleaning avoid second pollution and save time and labor.

7. Dust inertia separation at the furnace outlet can reduce exhaust gas concentration and lessen abrasion of rear heat surface.

8. Compact structure makes its installation volume smaller than other types of boilers, it will shorten installation period and lower boiler room cost.
