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.
Thermal Power Station process flowchart and diagram. The fuel is transported from mines via trains to the fuel storage facility in a power plant. The fuel transported to the plant is generally bigger in particle size and before it is fed to the boiler furnace it is broken down into smaller pieces using crushers.The fuel is then fed to the boiler generating a large amount of combustion heat.
Aug 08, 2018· Pollution control in coal power plants is critical. In this blog, we explore the different technologies used and the differences between them. Pollution Control. Thermal Power Plants produce electricity by first creating heat, and the U.S.A. still produces most of our energy by burning fossil fuels (coal, natural gas, or oil) to create this heat.
Power plants are by far the largest contributors of toxic pollution to U.S. waters. In 2013, the U.S. Environmental Protection Agency found that power plants dump more pollutants, such as mercury, arsenic and lead, into our waters than the next nine industries combined. The heavy metals in the waste discharges can cause neurological and developmental damage, cause harm in utero, damage
Mar 06, 2017· T he region has been investing in new power stations to meet its mammoth energy needs, b ut a major effort is also underway to modernize the existing fleet and make it efficient enough to meet the Indian government’s ambitious targets to reduce air pollution. The Ramagundam plant’s operator — the National Thermal Power Corporation
Improving efficiency at coal-fired power plants is a path of no regret: A more efficient plant uses less coal, has lower emissions, and lower costs.
That’s the exhaust stack for a large WTE plant, commissioned in 1985, now operated by Wheelabrator Technologies, and long a target of environmental activists for alleged air pollution problems.
Dec 16, 2017· How to control Sox and NOx emission in Power Plant Now these days power industries left huge amount of smoke in the enivorment which causes the air pollution. This smoke is comes out from the boiler chimney in the form of waste flue gases which are generated from the combustion of fuel.
Jul 28, 2008· Coal and global warming. Of coal’s many environmental impacts, none are as harmful, long term, and irreversible as global warming. Global warming is driven by emissions of heat-trapping gases, primarily from human activities, that rise into the atmosphere and act …
On December 16, 2011, the Environmental Protection Agency (EPA) finalized the first national standards to reduce mercury and other toxic air pollution from coal- and oil-fired power plants. More than 20 years after the 1990 Clean Air Act Amendments , some power plants still do not control emissions of toxic pollutants, even though pollution
Oct 29, 2010· Key Power Plant Rules Overdue • The American public has suffered avoidable deaths and illnesses as important Clean Air Act-required power plant controls have been delayed more than a decade. • The Act required states by 2000 to adopt rules as needed to control interstate pollution to help meet health-based air quality standards issued in 1997
