steam water tube coal 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.
Definition of Boiler
We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt

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

A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.
Water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. ZOZEN’s water tube boilers can be mainly divided into D-type, A-type, and π-type, which have been exported to Indonesia, Pakistan, Philippines, Malaysia, Vietnam, Russia, Thailand, Australia, Algeria, Outer Mongolia, Papua New

It is a fire tube, horizontal, internally fired, and natural circulation boiler, stationary and low-pressure boiler. Since it is a low-pressure boiler steam production will be less. Due to the lower steam production, the efficiency of the boiler is also low compared to the water tube boiler. The Lancashire boiler is shown in the figure below.

A boiler is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy.
