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.
Hydraulically driven moving rows of grate bars with variable length & number of strokes. Zoned partition walls below the grate for separation of different primary air zones. As the fuel moves from the inlet to the discharge it passes through distinct drying, volatilization, combustion and burn-out zones.
It consists of a continuously moving grate. Coal is deposited on one end of the grate by gravity feed from a coal hopper. The coal depth is adjusted by a guillotine-like movable coal gate to a thickness of about 4 to 12 inches. The coal is burned as it passes slowly through the furnace at grate speeds …
Combustion grates. Multi-fuel boilers. There are no mechanical joints or moving parts under the vibration grate that need lubrication. As it is thus only the strength of the construction materials that set the limit, the under-grate air can be preheated to 300°C without any problems.
Author: Walter T. Ray, Henry Kreisinger Moving Grate Principle Grate Construction. The grate system in a Justsen boiler is unique as each grate is placed on 5 water-cooled tubes which circulate through the boiler. The grates don't move, providing a very stable connection to the water-cooled tubes and optimum heat transfer to the combustion water.
Boilers aren’t always installed in the most convenient of places and if you’ve taken the decision to move your boiler, you’ll need to think about the potential cost. Typically, moving a boiler will cost £300 – £800 and take 1-2 days but this will vary depending on how far you want to …
Wood fired moving grate steam boiler is single drum water tube and fire tube boiler, combustion equipment is moving grate. Water wall tubes at left and right sides of furnace are the radiated heating area.This wood fired chain grate steam 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
THE SIGNIFICANCE OF DRAFTS IN STEAM-BOILER PRACTICE. By WALTER T. RAY and HENRY KREISINGER. INTRODUCTION. This preliminary bulletin is the first of a series of two or three on the significance of drafts in steam-boiler practice, the succeeding bulletins to be along the same lines but of a more advanced char acter.
1,104 moving grate boiler products are offered for sale by suppliers on Alibaba.com, of which boilers accounts for 18%, boiler parts accounts for 7%, and heating equipment accounts for 1%. A wide variety of moving grate boiler options are available to you, such as industrial, power station.
Stationary Boiler Grates. Stationary grates The grates were stationary. These were primarily for wood fired boilers. The air space is ¾” in a herringbone (V-shaped) design. The ¾” air space allows the ashes to drop into the ash pit.
As a widely used heating equipment in industrial field, traveling grate boilers combine many patented designs and are leading in the world. It adopts the latest combustion theory product of Xi'an Jiaotong University, could burn different kinds of coal fuel and biomass fuel in a high combustion efficiency.
