coal fired water tube hot water boiler - Bing is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.

The wood fired chain grate hot water boiler uses the new scientific achievement, such as arch tube plate, screw fire tube to solve the problem of tube plate flaw, water wall tube explosion, low efficiency, insufficient output, and poor adaptability of fuel.
SZL series vertical dual drums chain grate water tube hot water boiler, adopts quick fitting and assembly structure. The 4-6t/h boiler is of quick fitting tube structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components.
DZL horizontal chain coal-fired hot water boiler is a horizontal three-return water-fire tube boiler. Two fire tubes are arranged in the drum, and water-cooled wall tubes are arranged on both sides of the furnace.
Hot water boiler as a part in production and living has some risks, for example, water cooled wall tube explosion during its operating, people need to process safety inspection and maintenance in advance to to prevent horizontal coal fired hot water boiler water wall tube explosion happening.
Alibaba.com offers 68 coal fired pipe tube hot water boiler products. About 97% of these are Boilers. A wide variety of coal fired pipe tube hot water boiler options are available to you, such as pressure, structure, and style.
Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen

The coal or biomass was feed by workers manually. It is mainly composed of furnace, seal ring, horizontal water tubes, circular flue, gauges, valves and chimney. After burning in the fire grate, the exhaust gas pass through the horizontal water tube, and the small carbon block and dust in the exhaust gas fall on the fire grate and re-burn.
Heat cold water into hot water for central heating or washing. For hot water boiler, EPCB has coal fired hot water boiler, biomass fired hot water boiler, oil fired hot water boiler, gas fired hot water boiler, electric hot water boiler, which the capacity is from 60kw to 21MW.
