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.

high temperature water boilers intended for operation at pressures exceeding 160 psig and or temperatures exceeding 250 degrees F.
A boiler is an closed vessel that produce steam from water utilizing combustion of oil or gases.Hot water or steam circulated inside the pipe and transfer heat in many industrial applications.Classification of boiler are discussed bellow.
The heat radiates from the hot water in the radiator(s). The water cools. Cooled water returns to the boiler via gravity or a separate pump. The cooled water flows back to the boiler to be reheated. It should be noted that hot water boilers are not the same as hot water heaters. Water heaters heat the water for your shower, dishwasher or tap water.
Hot-water systems can be classified by operating temperature into three groups. low temperature - LTW; medium temperature - MTW; high temperature - HTW; where. Low Temperature Hot-Water Heating System - LTW. operates within a temperature of 250 o F (121 o C). The maximum allowable working pressure for a LTW system is usual 30 psi (2 bar).

Two primary types of boilers include Fire- tube and Water- tube boilers. In a Fire-tube boiler, hot gases of combustion flow through a series of tubes surrounded by water. Alternatively, in a water – tube boiler, water flows in the inside of the tubes and the hot gases from …
Sectioned fire-tube boiler from a DRB Class 50 locomotive. Hot flue gases created in the firebox (on the left) pass through the tubes in the centre cylindrical section, which is filled with water, to the smokebox and out of the chimney (stack) at far right.
