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.
CO ×(44 28), to insure that total carbon compounds emissions (CO 2 and CO emissions) represent not more than 100% of the carbon contained in the fuel. 2 The second program was developed to estimate the national and regional environmental impact of a widespread adoption of modern cogeneration in the rice, sugar, wood and palm-oil industry
Cited by: 18 Most modern biomass boilers that we sell generate 0.5-1% of ash to the volume of fuel used. This means that the large ash bins need to only be emptied every 6-8 weeks. Wood fuel ash makes great fertiliser as it is high in nitrates.
Modern biomass combustion systems are highly sophisticated, offering combustion efficiency and emission levels comparable with the best fossil fuel boilers. Using modern technology they can currently operate at 90% efficiency which is vastly higher than conventional boilers and electric heating systems.
Cited by: 6 Biomass boilers are less polluting than wood-burning stoves, which were recently blamed for high smog levels in London, and are seen as a low-carbon source of heat.
while achieving efficient combustion, low emissions, and no net CO 2 releases to the environment. Biomass boilers equipped with new combustion techniques to enhance efficiency resulting in lower heat rates, as well as new, proven emissions control devices to significantly reduce NO x and CO emissions, have been developed to meet this need.
Cited by: 742 Most modern biomass boilers will have a burn efficiency of 90 to 95%. This is the same as a brand new condensing boiler, though older oil boilers will likely be around 60 to 70% efficient. It is important to ensure good quality fuel is used and that system is serviced as per the manufactures recommendations to ensure the efficiency levels are kept
Wood‐Fired Boilers.”1 While the study identified and evaluated many ways to reduce emissions, it did select a single add‐on control technology (the Core Separator™) as “BACT” or Best Available Control Technology for controlling particulate matter emissions.
File Size: 1MB BIOMASS EMISSIONS AND CLEAN AIR ACT REQUIREMENTSOur market-leading, cutting-edge biomass boilers are among the first in the UK to have passed vital emission tests set by the energy watchdog Ofgem. Rural Energy's Herz range, including the Herz Pelletstar, Firematic, BioMatic and BioFire biomass boilers, now have Ofgem’s Renewable Heat Incentive Energy Performance …
Hurst Boiler & Welding Co., Inc manufactures its biomass boiler systems with an extended burn chamber, increasing dwell time for the combustion of any unwanted particulates and emissions before they are able to exit the system, making the process much cleaner, which reduces maintenance time and costs.
emissions (~1%), although the increasing use of solid biomass boilers for primary heat or combined heat and power applications may influence NO x concentrations at a local scale. The installed capacity of solid biomass boilers registered in England under the non-domestic …
This means traditional boilers will become increasingly expensive to run and wood burning stoves will need to comply with the requirements of the new emissions regulations and cannot be fitted after that date. Biomass boilers and Wood Pellet Stoves (Biomass Burners) are the solution
