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.
Packaged Boiler: Intech Boiler. Intech as it’s name implies is a 3 Pass Internal Furnace Packaged Boiler.It is a conventional 3 pass smoke-tube design, designed for the combustion of coal and wood in an internal furnace and is therefore sometimes known as coal/wood fired Steam Boiler.. This Packaged Boiler comes in dry back, semi-wet back, and fully wet-back options and is most suitable for
WNS series boiler is well known as a horizontal style three pass wet back boiler.This type boiler used widely in industries and can be designed as steam boiler or hot water boiler according customer inquiry. The fuel of WNS series horizontal style 3 pass wet back boiler can be oil or gas,which is fast-loading internal combustion three return fired tube boiler.
Thermic Fluid Heating system is a fully automatic packaged, oil/gas fired 3 pass heater in which Thermic fluid can be heated upto 300° C almost at atmospheric pressure. Thermic fluid heater is a closed circuit unit in which a hot thermic fluid is circulated.
Aug 01, 2000· Boiler bypass lines must be installed with care to prevent serious difficulties from developing in the system. A circulator on the boiler side of the bypass raises the return water temperature. A circulator on the system side of the bypass lowers the supply water temperature. Boiler manufacturers emphasize bypass lines today—and with good reason.
Apr 04, 2016· Intech (3 passes Internal Furnace Packaged Boiler) Boiler is the conventional three pass smoke-tube design coal/wood fired steam boiler having the internal furnace.

LOW PRESSURE BOILER. Modified three-pass scotch marine steam boiler. Designed to fit through a standard 36"x80" door. Durable features start with the thickest vessel shell in its class, along with large furnace volume for ultimate combustion efficiency. Skid Mounted and Modular Packaged.
The Johnston boiler is a steam or hot water packaged firetube boiler, ranging in size from 50 to 2,500 horsepower, 15# to 350# design pressure, 3 or 4 pass, of welded steel construction with submerged rear combustion chamber. The package consists of a pressure vessel, base frame,
A package boiler is a factory-made boiler. Package boilers are available in a range of standard designs. Package boilers are used for heating and act as a steam generator for small power purposes such as self-powered industrial plants. They cannot be used for large-scale power plants such as co-generation plants due to their size and lack of efficiency.
