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.
Zhengzhou Boiler Co., Ltd is committed to using advanced technology to innovate traditional boilers, we have types of chain grate coal fired boilers for the companies in India, to improve energy efficiency, reduce emission of waste gas and build a sustainable, environment-friendly.
Manufacturer of Fire Grates, Travling Grate, Spreasder Stocker Grate, Screw Feeder, Dumping Grate Boiler, Coal Combustion Grate, Pasalting Grate, Mumbai, India
Chain Grate Boilers fuel can be coal, lean coal, biomass, Coal fired boiler types have DZL, SZL, SHL, DHL, get the coal fired chain grate boiler price now
The main types of stokers are: Chain-grate or travelling-grate stoker; Spreader stoker boiler; 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 …
SZL Series Biomass Chain Grate Boiler 2 years ago Lisa Type: SteamHot Water Boiler Capacity/Hot Power: 6 – 25Ton / 4.2 – 17.5MW Pressure: ≤1.6MPa…
The aforementioned boiler types typically fall into one of the following combustion method categories: Stoker Stokers burn lump coal. Spreader stokers feed a continuous supply of coal onto the bed. A chain-grate stoker (sometimes called a traveling grate stoker) deposits the fuel in one area where it is then distributed by a moving grate
Traveling or Chain Grate Stokers Traveling or chain grate stokers feed coal out onto a rotating metal belt that supports the fire. Coal is fed from a hopper. Grate speed is automatically controlled to maintain desired steam pressure. Burning progresses as the belt moves from front to back of furnace.
Its performance and operation is constant and reliable. More and more plants prefer this type chain grate because of its good structure. Flake type chain grate stoker has two types: Small flake type chain fire grate: for 4t/h to 25t/h boiler Big flake type chain fire grate: 25t/h to 60t/h boiler. Technical Parameter
There are various types of Grates available like Travelling grate, chain grate, inclined water cooled grate, pin hole grate, dumping grate, fixed grate ..etc. Travelling Grate is widely used for high ash content fuels and medium range boilers. Dumping grate is widely used for low/medium capacity boilers and low ash content fuels like Bagasse.
Our Patented Coal Catalyst products improve coal combustion and reduce harmful emissions. Coal Catalyst improves energy efficiency and reduces your operating costs. CC-88 eliminates carbon waste, which improves coal fired boiler performance by reducing slagging and fouling of the boiler system.
