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 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
The efficiency on a lower heating value (LHV) basis increases slightly from 91.44% at 25% load to about 60% load and then tapers off. To determine burner duty, divide the boiler duty by the efficiency. Using a performance sheet obtained from a boiler supplier, one can …
File Size: 379KB Dec 11, 2017· The temperature range between various parts of the boiler is reduced which results in reduction of stresses due to unequal expansion. If the boiler is fed with cold water it may result in chilling the boiler metal. Hot fed water checks it. Evaporation capacity of the boiler is increased. Overall efficiency of the plant is increased.
The larger capacities of a steam and hot water boiler are powerful enough to support large-scale, high demand critical operations that see swings in steam demand. The water stored in the steam boilers allows for a much better response to changing steam demand from the plant than the single through design of a steam generator.
The ET 810 trainer contains the main components of a steam power plant: a gas-fired steam boiler, a single-cylinder piston steam engine with a generator, a condenser, a feed water tank, and a feed water pump. The steam boiler generates water steam and supplies it to the piston steam engine.
File Size: 570KB Start studying Plant Theory - Chapter 56 : Boiler Draft Equipment. Learn vocabulary, terms, and more with flashcards, games, and other study tools. they are usually balanced draft to increased efficiency. This is normally done by sensing the steam pressure in the boiler or main steam header.
The sizes and speeds of the turbines are optimized for energy capture at the different steam temperature and pressure ranges at each stage. In this type of plant overall efficiency can be raised by taking the steam that exits the high pressure turbine and heating it further to add energy before feeding it into the intermediate pressure turbine.
For example, if a CHP system is natural gas-fired and produces steam, then α represents the efficiency of a conventional natural gas-fired boiler. Typical boiler efficiencies are 80 percent for natural gas-fired boilers, 75 percent for biomass-fired boilers, and 83 percent for coal-fired boilers.
1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.
This is a small low cost miniature power plant designed for educational purpose. A hand feed pump supplies water from a feed tank to a small gas fired boiler. Steam is throttled to a single cylinder, double acting reciprocating engine. A small DC generator is connected to the engine by …
A Fresnel solar boiler is used to investigate the influence of a superheated-steam generating solar add-on on the overall performance of a 350 MW coal-fired power plant in two promising places for this type of technology. The solar boiler supplies steam to the preheating stages of the power block in order to reduce the steam extraction from the
