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.
Jun 30, 2017· Dong Energy has used wood chips and pellets in increasing percentages at two of its power plants, Herning and Avedøre (near Copenhagen), since 2002. Last year, the Avedøre and Studstrup (near Aarhus, Denmark) power stations underwent conversions to operate on 100 percent biomass, mostly wood pellets, but some straw as well.
Wood gasifying boiler PyroBurnA highly-efficient wood gasifying boiler designed for WBSSteel wood-fired boilers WBS range in nominal output from 20 to 110 kW to satisfy the Simple installation and handling Pellet burning boiler PelleBurnPellet burning boiler.
Biomass stoves are room heaters that use logs, briquettes or pellets. Stoves with back boilers can also be specified to meet central heating and domestic hot water demand. Prices can reach £5,000 for a fairly sophisticated pellet stove with back boiler.
Cichewicz CWD group offers wide range of solid fuel boilers for wood, coal, pellets in capacity range 17-600 kW. CWD produce boilers with upper and down combustion or gasification boilers and burners equiped with multi air system for multifuel and biomass : straw, wood.
Pellet boiler burns pellets manufactured by wood pellet mills.Wood produces such as wood sawdust, wood chips, branches are common raw materials of biomass pellets. Nowadays,straw materials such as wheat straw, ice husk, corn straw,sorghum, peanut straw, soybean straw , alfalfa straw and cotton stalk are also widely used in pellets processing.

BALE BOILERS. For farmers, rural businesses and local communities looking for cost-effective heating systems, straw-fired biomass boilers offer significant advantages. Straw is thermally efficient, and cheaper than all fossil fuels and other forms of biomass. It is readily available as a by-product of agriculture and requires minimal processing
Description of Szl biomass pellet/ sawdust fired steam boiler straw pellet wood generator: DZL series steam boiler is the kind of automatic, horizontal, three-pass, and fire tube boiler; water wall tubes are arranged along both sides of the inner furnace; it is equipped with high efficiency cyclone, and dust concentration can meet the environmental requirements of second-class area; equipped
Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers. A stove burns logs or pellets to heat a single room - and may be fitted with a back boiler to provide water heating as well. A boiler burns logs, pellets or chips, and is connected to a central heating and hot water
Faust biomass-boilers. Faust produce automatic and manual biomass boilers for straw, tree trunks/logs, wood pellets and wood chips. Faust also produce augers, rotary valves, spring feeders, hydraulic walking floor systems, straw rakes and handling cranes to ensure the correct operation of our boilers.For the flue gas line we produce convection tubes, cyclones, multi-cyclones, filters, flue gas
