WNS series horizontal internal combustion boiler 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.
1. 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.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. 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.
4. 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.
Jun 07, 2016· Modern sub critical power stations have a thermal efficiency of 39%.How do I get that? Efficiency=860/Heat Rate. If all the chemical energy in the gets converted into electricity,it will take 860 Kcal of heat to generate 1 unit of electricity.Unfo
Coal saving: secondary combustion technology make sure the boiler is energy saving, environmental friendly product, which means it will save 30-50% coal than last generation CDZH hot water boiler Large heat exchange surface: high thermal efficiency and fast temperature rising speed
2. The fire chamber has a special design—cyclone re-burning chamber, which reduce the dust content of emission and make the carbon black powder burning completely. It will increase the boiler efficiency and reduce the concentration of emission.
The ATO-540H-N tankless water heater uses up to 199,000 BTU/hr of natural gas to deliver an endless supply of hot water for a 3 bath home in northern climates and up to a 4 bath home in southern climates (one shower head per bath).
CDZL Chain Grate Coal Fired Hot Water Boilers is used to get hot water for domestic heating, greenhouse heating, bathe water heating application. CDZL Chain grate coal fired hot water boilers works under no pressure, so it is very safe. Advantage Feature of CDZL Coal Fired Hot Water Boilers

Coal fired hot water boiler is a widely used boiler type in heating, hot water, thermal power plant. The coal quality is very important that related to the hot water boiler operation and combustion efficiency. Coal quality importance in 7MW hot water boiler. 1.When the coal quality used in 7MW hot water boiler is poor, it is hard for the boiler
The coal hot water boilers from Keystoker make for a powerful heating option to use in your home, or commercial building. Using anthracite coal to burn, or oil if you purchase a dual fuel kit, this coal burning boiler can produce anywhere from 85,000 to 528,000 BTUs.
A coal-water slurry fuel is defined by a number of factors including its viscosity, particle size, rate of sedimentation, ignition temperature (800–850 °C [1,470–1,560 °F]), combustion temperature (950–1,150 °C [1,740–2,100 °F]), ash content and calorific value (3700–4700 kcal/kg).. When coal-water slurry fuel combusts, over ninety-nine percent of its carbon content is consumed
Features of Coal Fired Hot Water Boiler: 1. It's a adaptable to a wide range of fuels including bituminous coal, lean coal and anthracite; 2. Thermal efficiency 5%-15% higher than other boilers, annual cost savings for 10tph boiler as high as USD70000; 3.
CDZH coal and biomass horizontal hot water boiler is a horizontal three return water pipe mixed boiler,band heater 220v 35x45mm or band extruder barrel heater with band heater insulation jacket and a bunch of threaded pipe is arranged in the pot. The two sides of the furnace are equipped with a light tube water cooling wall.
