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.
How do biomass boilers work? Biomass boilers work by burning biological matter and outputting the resulting heat for use in heating systems.Wood pellets, chips, logs or other biological materials are fed – automatically, semi-automatically, or by hand – into a combustion chamber where they are ignited.
Benefits of biomass heating. The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and/or electricity with less effect on the environment than fossil fuels. This type of energy production has a limited long-term effect on the environment because the carbon in biomass is part of the natural carbon cycle
"chlorine induced corrosion" Question: "Our low pressure steam boilers (water tube design) have experienced oxygen pitting after only 5 months of operation. Our water treatment vendor has not made a change in 10 years and we never had a problem. Recently we changed out the boilers and feed water system, and now we have a problem.
Overview. Biomass boilers are heating systems that use the combustion of organic matter to provide heating and hot water. Biomass heating systems can be said to be carbon neutral because the carbon dioxide emitted when wood is burned is the same amount that was absorbed over the months and years that the plant was growing.
Biomass needs to be made dense to provide ease of mechanical handling and feeding, uniform combustion in boilers, reduced cost of transportation and ease of storage. The types of dense biomass to choose from are pellets, briquettes or loose biomass that has been dried before being fed into the boiler.
Biomass boilers & wood boilers. Looking for a highly efficient and sustainable biomass boiler, such as a wood boiler? HoSt has over 25 years’ experience with designing, building, operating and maintenance of biomass-fired boilers and wood-fired boilers. Wood-fired bio-CHP’s are extremely suitable for the greenhouse sector.
As long as biomass boilers are installed correctly and the right fuel is used, then they should have no more issues than a fossil fuel boiler. With over 800 systems sold ourselves as well as having a consultancy service that supports anyone with a problematic system, we have come across and rectified a range of issues over the past 15 years.
There is no more chance of a biomass boiler failing than there is of any other boiler. In fact, a biomass boiler will retain its efficiency (more than 90%) for maybe twice as long as a gas or oil boiler. One solution that many people like to consider, however, is to retain their existing oil or LPG set-up as a back-up.
