Coal boiler (also called coal fired boiler) is widely used to generate thermal energy by burning coal that is fed into the combustion room. Coal can provide lower operating cost in comparison to other fossil fuels like oil or natural gas. Our coal boiler has the characteristics of high efficiency, energy saving, integrated control, easy installation and safe operation.
DZL series coal fired boilers are specially designed and optimized to produce low pressure steam or hot water with rated evaporation capacity from 1 to 45 tons/hr and rated pressure from 0.7 to 1.6 MPa. The design heat efficiency of DZL coal boilers is up to 81~82%. These coal boilers cover big market share in domestic and abroad.
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.
