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.
Jan 04, 2018· Boiler Efficiency Boiler Efficiency is a term which establishes a relationship between energy supplied to the boiler and energy output received from the boiler. Boiler efficiency (%) = (heat exported by the fluid (water, steam) / heat provided by the fuel) x 100 3. Types of Boiler Efficiency 1. Combustion Efficiency 2. Thermal Efficiency 3.
Dec 08, 2017· 3 Power Plant Efficiency Learning Objectives. A schematic diagram of a simple steam power plant is shown below: Schematic diagram of a steam power plant. High-pressure steam leaves the boiler and enters the turbine. The steam expands in the turbine and does work which enables the turbine to drive the electric generator.
Power plant optimization is often associated with upgrading the performance of combustion and steam processes, but another prime candidate for efficiency improvement are the plant’s electrical
Turow 11 is expected to provide 43% net thermal efficiency, which is considered to be the world’s highest for a lignite-based power plant. Turow power station history and modernization details. The Turow power station originally included ten 200MW generating units commissioned between 1962 and 1971.
This paper presents briefly on the boiler efficiency evaluation procedures by direct and indirect methods useful in thermal power plants. In the direct method consideration is given to the amount of heat utilized while evaluating the efficiency of the boiler, whereas, indirect method accounts for various heat losses. The boiler efficiency evaluated by direct method is found to be lower than
Cited by: 1 3.2.6 Thermal efficiency of conventional power plants. The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable
Nov 24, 2016· 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) Boiler Efficiency by Indirect Method : Where the efficiency is the difference between the losses and the energy input.
Combined Cycle Power Plant CCPP September 1, 2019 Boiler articles , Power plant Articles Leave a comment 8,927 Views The objective of this article is to provide power plant personals with a basic understanding of the major components of the combined cycle power plant and the role of each component to achieve optimum plant efficiency.
Boiler Efficiency Improvement Steps: After Analyzing heat losses in industrial boilers, boiler engineers or technicians can help you to increase your boiler efficiency by 6% – 10%.. Here are the few boiler efficiencies boosting steps listed below:. Complete combustion of fuel so that no unburnt is left behind is a good practice and will add to the boiler efficiency.
Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the
Biomass has higher moisture which reduces boiler efficiency, again requiring more pounds of biomass to be fired. Biomass bulk density can be as little as 1/10 that of coal per unit heating value
