Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Cogeneration - Wikiped

Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Trigeneration or combined cooling, heat and power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector.The terms cogeneration and trigeneration can be

Waste Heat Boiler,Waste Heat Boiler for Chemical,Was

Waste Heat Recovery Boiler for Chemical. To most fertilizer plants and chemical factories, three waste mix combustion waste heat boiler is an ideal boiler system which can burn waste gas, waste water, waste residues from fertilizer production lines, making waste profitable as well as little waste discharge.

Northwest CHP Technical Assistance Partnership > Ho

With a shift in forest management priorities, this Oregon lumber mill was forced to downsize and focus more on high quality, low production specialty items. Seeking to dry more lumber, they needed greater boiler capacity to heat more dry kilns. This led to installation of a 1.5 MW cogeneration facility. Government incentives made the project

For paper mills and cogeneration, everything old is n

Jun 30, 2014· The paper and pulp sector ranks second of all industries in its current use of CHP, according to a 2012 paper by the trade group. A 2013 study by the World Resources Institute noted that Midwest paper and pulp mills have 1.3 GW of installed CHP capacity, and nationally there is about 7.2 GW of CHP in pulp and paper mills. Wisconsin mills have

generation capability of Washington State pulp and paper mills. The sources and types of fuels used in various boilers were assessed and the age profile of boilers currently in pulp and paper mills was determined. Phase 2. Assess the energy potential for Washington State pulp and paper industry with state-of-the-art technologies.

Waste Heat Boilers - Clarke Ener

Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling circuits. This high temperature and flow makes it well
