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.
considerably reduce the power output and efficiency of a combined cycle power plant. This is caused by reduced heat transfer efficiency and increased backpressure to the gas turbine. Pressure wave cleaning has proven to be an effective technology for removing this fouling. Pressure waves penetrate deeper within the finned tube bundles than other
Apr 09, 2018· The coal power plant diagram shows the components of the plant and the different stages of transforming the chemical energy (coal) into electrical energy as: We started with the boiler or the steam generation system; as we supply the coal from coal bunkers via coal conveyors to …
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.
Rotor Air Cooler / Kettle Boiler HX. Our Shell & Tube Rotor Air Cooler Kettle Boiler Heat Exchangers are used to cool gas turbine rotor cooling air in a Combined Cycle Power Plants. The rotor air heat is tranferred to the water on the shell side, which is converted to steam and piped into the HRSG.
Because of this the combined cycle can be operated only in locations where these fuels are available and cost effective. Developments for gasification of coal and use in the gas turbine are in advanced stages. Once this is proven, Coal as the main fuel can also be used in the combined cycle power plant.
Feb 25, 2017· ME4293 Combined Cycle Power Plant Spring2017 Southeast Asia's largest single-shaft combined cycle power plant (L) - Duration: Boiler tube failures in Eskom coal fired power stations
Combined cycle power plant is a cycle that utilizes exhaust gases from gas turbine (power plant) to heat water in the boiler, in this case is called HRSG (Heat Recovery Steam Generator) and the steam that is produced by HRSG is used to drive steam turbine.
Maintaining plant safety and reliability with proven asset lifecycle services. Structural Integrity is uniquely positioned to help power plant owners and operators meet the lifecycle challenges that face coal or gas fired plants, and combined cycle plants.
May 05, 2019· If you consider the coal plant and the combined cycle plant then, for building a combined cycle unit you require half of the money than that required for constructing the coal power plant. The abundance of fuel sources: For running the CCPP, you have large fuel resources like natural gas. Nowadays, biogas is also in use for operating the CCPP.
