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.
Boiler natural gas feasibility studies are required to determine the effects of burning natural gas in a coal -fired boiler. Coal and ash handling equipment are not required if firing natural gas…
Apr 27, 2020· Coal steam power plants require more energy input per megawatthour of generation than natural gas-fired combined-cycle plants. Yet, the low cost of coal relative to natural gas until recent years favored the use of coal-fired generating units to fulfill baseload electricity demand, leading plant operators to run these units at rates close to their output capacity during peak demand hours.
Jul 16, 2014· Two massive natural gas boilers were installed at the Vanderbilt Power Plant July 12 as part of the university’s ongoing effort to convert the co-generation facility completely to natural gas. The new boilers will provide steam to more than 5.8 million square feet of building space at the university and medical center.
Converting a coal fired boiler to natural gas has several major advantages from an emissions performance perspective. Natural gas contains minimal (or zero) amounts of sulfur, mercury and
The ROI of SCR Catalyst Testing Conventional (boiler and turbine) power plants use a variety of resources such as coal, oil and natural gas as fuel to generate power. MHI group has an extensive record in meeting the global demand of conventional thermal power stations, including providing highly-efficient ultra-supercritical pressure boilers with an output of over 1,000MW.
Firing natural gas causes a significant change to the boiler heat profile as compared to firing coal. Because firing natural gas nearly eliminates slagging and fouling of boiler tubes, the heat released by burning natural gas is absorbed lower in the furnace.
Converting an existing boiler is typically 15% to 30% of the cost of installing a new natural gas boiler. Additionally, converting coal boilers to firing natural gas provides the following major
File Size: 796KB In this configuration, a gas turbine is added to an existing plant and the exhaust from the turbine is ducted directly to the boiler windbox, where it is used as combustion air for the boiler.
Author: Dale Stevick The natural gas supply system to the boiler utilized a single flow control valve for all the burners. The plant operation wanted the ability to bias heat input in between different levels of
Aug 31, 2012· Industrial and large commercial energy users with oil-fired boilers are changing to natural gas, and the incentives are stronger than ever. Michael Collins is from Yankee Gas Services Co., a Northeast Utilities company.Collins said, “When natural gas …
