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.
Several observations could be made from the thermal test and energy analysis of sample boilers: (1) The energy loss of coal-fired industrial boilers was mainly caused by two items: Q 2 and Q 4 due to unburnt carbon, both of which account for about 10% of the losses. (2)
The quantity of ash produced per unit of fuel must also be known. This loss generally applies to solid fuel fired boilers. A small loss due to un-burnt carbon would also occur while burning fuel oils. b) Heat Loss due to Dry Flue Gas The major energy loss in a boiler occurs through flue gases, which escapes at …
Apr 14, 2015· In this lecture we look at a complete problem involving coal combustion. Material and energy balances are conducted and various concepts such …
ENERGY STAR Most Efficient 2020 — Boilers. The ENERGY STAR Most Efficient 2020 designation recognizes the most efficient products among those that are ENERGY STAR certified.These exceptional gas and oil boilers represent the leading edge in energy efficient products this year.
Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high-efficiency versions of all types of furnaces and boilers are currently available. To learn more about furnaces, boilers and other types of home heating systems, explore …
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.
Cited by: 10 Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity.The process that does this is known as the Rankine cycle.The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.All but a small fraction of the world's primary energy comes from fuels, and about three-quarters of
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
Aug 27, 2018· Boiler System Energy Losses The Boiler Efficiency Calculator takes into account only major energy losses‚ which typically represent 10 to 20 % of fuel input. The major energy losses associated with boilers fall into two categories: stack losses‚ and radiation and convection losses .
Heat loss with unburnt carbon This loss can be divided into : Carry over loss Loss with slag or bottom ash The carry over loss is much predominant over 26 the loss with slag. The carry over loss is determined by the carbon content in Fly ash samples collected from ESP hoppers. The slag loss is determined by the carbon content in bottom ash samples.
Mar 01, 2019· Energy conservation boiler 1. ENERGY CONSERVATION Topic “Boiler”[ 1 ] 2. BOILER A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process. Heat is transferred from one body to another by means of: (1) radiation (2
