Manufacturer of Coal Fired Hot Water Boiler - DHL Coal Fired Boiler – Taishan Group

DHL Coal Fired Boiler Product Description DHL series boiler is single drum horizontal chain grate bulk boiler. The burning part adopts flake chain grate to match with high-quality auxiliary equipment and perfect automatic control system, which ensures safe, stable and efficient operation of boiler. DHL series coal fired boilers are designed and optimized for applications to produce low, medium and high pressure steam or hot water with rated evaporation capacity from 10 to 65 ton/hr and rated pressure from 1.25 to 9.8 MPa. The design heat efficiency of DHL coal boilers is up to 81~82%. Features: 1. High efficiency, low fuel consumption; low operating costs 2. High safety level, panel-type heating surface in the furnace, furnace heated evenly. 3. Improve the furnace temperature field to ensure safe operation of the boiler 4. 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. 5. 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. 6. 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. 7. Environmental protection effect is good, use multi-level dust removal, reduce exhaust gas concentration, Ringelmann blackness is less than 1. Application: DHL series coal fired boilers are widely used in chemical industry, paper making industry, textile industry, food industry, pharmaceuticals industry, heating industry, construction industry.
