bituminous coal boilers coal fired boiler efficiency

1.Boiler design structure

1, The usage of high-performance heat transfer components - threaded pipe, with a reasonable gas flow rate, the boiler thermal efficiency is higher 6-8 percentage points than the state high professional standards.
2,Arch tube plate, thread to make pot pipe from the quasi-rigid body shell variable based elastomer with the airfoil stack, completely avoid the defects that traditional high-temperature pyrotechnic tube boiler tube plate cracking.
3, Reasonable and unique water circulation loop backwater ejector device (hot water boiler), improved the increased water velocity, to avoid the water-wall tube break.
4, The usage of inertial separation of dust furnace, supplemented by high-performance multi-collector, so that the concentration of dust emission boiler to meet the demand for a class.

2. Boiler advantage:

1.Safety: with water level, leakage steam, steam pressure control. Make sure boiler working safety.

2.Product quality ensured by:Strength calculation report , hydraulic test, X-ray, non-destructive test.

3.Efficient: well insulation and excellent structure.

4. Spirally conrrugated tube increase the strength and also meets the needs of heat expansion of each parts.

3. Our Main Product scope:

1.WNS series Horizontal oil/gas fired boilers (0.5-30T/H, 0.7-14MW)
