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.
There were more than 54 nos Travelling grate boilers operating in India which were designed as per Doosan Power System design and supplied either directly from the UK or produced by their licensees. Today, many of them have either been retired or converted to FBC due to change of coal quality.
Solid Fuel Boilers Stoker Grate Combustion FSE Energy brings over 75 years of experience and unparalleled quality to the utility and industrial grade boiler marketplace in stoker grate combustion solutions in the output range of 10K PPH to 650K PPH.
Travelling Grate or chain grate Stoker Boiler In Travelling Grate boiler coal is fed at one end of a moving steel chain grate. As grate moves along the length of the boiler furnace, the coal burns before dropping off at the end as ash.

refractory cells to stationary grate spreader stokers to stokers primarily designed to burn coal. In 1938, in the United States, the traveling grate spreader stoker was developed to burn coal and quickly became the predominant firing equipment for industrial coal fired boilers. In 1944, the first traveling grate spreader was
Jan 20, 2018· In the spreader stoker arrangement, a high-speed rotor throws the coal into the furnace over a moving grate, to promote fuel distribution. Such boilers have commonly used in sizes equivalent to 10-25 MWe, but emissions control tends to be uneconomic from such units, apart from the use of cyclones for particulates removal.
Author: RUSHAS ENGINEERING CO.PVT.LTD. traveling grate fired boiler – boiler type,boiler type . 2018-10-4 · Jul 12, 2016 A fire tube boiler setup directs heated gases into a number of tubes that run A chain-grate stoker (sometimes called a traveling grate stoker) Biomass fired boiler – travelling grate boiler.
As the name indicates, Grate fired boilers or Grate Fired steam Generators are those boilers where the solid fuels are fired on grate. The grates can be inside the furnace or outside (external furnace boilers). These boilers are also called as Stoker fired boilers.
DSC-GTS Reciprocating Biomass Stoker The Detroit® RotoGrate Stoker is a continuous ash discharge, traveling grate, spreader stoker that is perfect for a broad range of applications. It is recognized worldwide for its efficiency in generating steam and power.
The grate, which forms a "floor" in the furnace, is an AET BioGrate travelling grate. The continuously-moving grate carpet slowly transports the burning fuel layer towards the boiler front where the ash falls into the ash pit. The grate speed can be adjusted to account for variations in fuel quality and ash content.
Coal-fired boilers can be classified regarding the type of a furnace: grate boilers (stoker), pulverized fuel-fired boilers (PF), fluidized-bed boilers .
