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.
Author: Gia Nicolaides Dec 10, 2018· “Eskom has 47,000 megawatts of installed capacity. Its plans to cut down operations, whether as a power station or units within power stations, was supposed to be 7,500 megawatts.
User rating: 3/5 The coal-fired Congella Power Station in Durban and Salt River Power Station in Cape Town were the first power stations built by Eskom, both complete in mid-1928.  One of Eskom's first power plants was a coal-fired 128 MW station in Witbank completed in 1935 to provide power to the mining industry.
Mar 25, 2015· Eskom was told to stop building additional stations soon after there was talk about it being unbundled or privatised, but the new directives from the government were vague and confusing. “Eskom
Headquarters: Sunninghill, South Africa Eskom has begun shutting down its old power stations, with the closure of three units at the Hendrina power station near Middelburg in Mpumalanga. Wits academic Jacklyn Cock told delegates at the Just Coal Transition symposium in Cape Town on Wednesday that Hendrina’s remaining units were to be shut down by April 22.
The Eskom Power Series was conceived in response to one of the most significant concerns facing utilities around the world - the continuing loss of critical technical skills and experience. Each year a growing number of technical experts are leaving the power utility industry, taking with them their knowledge, experience and expertise acquired
Author: Antoinette Slabbert Eskom suspends 3 power station managers over coal supply shortage. Six of the 15 power stations are running low on coal but the utility says the recovery plan is working well to ensure the lights
History: In 1965/66 contractors started with roads, pipelines and ground works on the farm Rietkuil, which Eskom bought from seven owners. Sufficient water and especially coal supply in the Rietkuil area ensured that the construction of Arnot Power Station commenced in 1968.
