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.
Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
2013-10-8 · REVIEW OF STATE-OF-THE-ART WASTE-TO-ENERGY TECHNOLOGIES . January 2013 . Client . Waste Management Branch The investment cost for the Amsterdam plant was in the order of € 370 million. The depreciation period was set The flue gas leaves the first heat exchanger downstream from the waste heat boiler at a temperature of 180°C,
The aggregated investment cost for installing the heat-exchanger and flash-steam tank was about USD 8,200, which included the equipment price, installation and other costs. Therefore, utilization of the blowdown waste-heat resulted an annual energy and cost saving of 2% energy used in the boiler. The payback period was less than one year.
Industry Trends. Waste Heat to Power Market size was valued over USD 15 billion in 2018 and annual capacity addition is anticipated to exceed 14 GW by 2025.. Get more details on this report - Request Free Sample PDF Paradigm shift toward the integration of renewable energy resources along with rising global energy demand is set to drive the waste heat to power market size.
The words “safely and economically recover waste heat” also mean “no-risk return on investment” which is exactly what Cain Industries heat recovery systems represent. By installing a fuel saving economizer on a combustion source, the BTU recovered pays for all the equipment installed, usually in 12 to 18 months (or an equivalent return
File Size: 873KB RD&D to advance waste heat recovery technologies. Technology needs are identified in two broad areas: 1) extending the range of existing technologies to enhance their economic feasibility and recovery efficiency, and 2) exploring new methods for waste heat recovery, especially for unconventional waste heat sources.

A waste oil boiler represents a profitable investment, since all the costs associated with buying and installing the boiler will pay themselves off in a short period, due to considerable savings coming from using the waste oil to run the boiler, which is a very cheap
Chapter 4: Investment Costs and Profitability of Biomass Heating Plants 59 4.1. Austria The energetic utilisation of solid biomass has a long tradition in Austria and is still a very important factor within the renewable energy sector. The consumption of final energy from sold biofuels increased from 142 PJ for 2007 to 164 PJ for 2010.
Heat Exchange Applied Technology Inc. Economizers dramatically reduce boiler fuel consumption by efficiently removing waste heat from the flue gas and returning the heat to the feedwater system. Our customized analysis allows optimum, cost effective operation of your system to ensure the greatest return on investment and shortest payback period.
