Coal fired steam boiler — type Natural Circulation. The complete factory specification follows. Quantity and destination market determine the final price — tell us both for a firm quote.
Combining fire tube and water tube sections in one coal fired steam boiler is a deliberate compromise: the water tube section raises steam quickly while the fire tube shell provides the buffer volume that handles demand swings. The low pollution claim matters in markets tightening coal emission limits. 6 ton output with PLC control on pressure parts, in horizontal natural circulation form.

3. What about after-sale service?
We will supply professional after-sale service team as soon as we receiving your problem feedback, and dispatch our engineers to your country and solve your problems right now.
4. What’s the advantages of your company?
4.1 Reasonable heat surface and burning device, heat efficiency is 4%~5% higher than national standard.
4.2 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.
4.3 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.
4.4 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
4.5 1-20T/H & 0.7-14MW boiler adopt big and high strength grate, add rolling device improves the boilers’ 4.6 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.
4.7 Dust inertia separation at the furnace outlet can reduce exhaust gas concentration and lessen abrasion of rear heat surface.
4.8 Compact structure makes its installation volume smaller than other types of boilers, it will shorten installation period and lower boiler room cost.
4.9 Big water volume benefits for power-off protection, high ability suitable for load changing.
