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.
File Size: 719KB This husk is used as fuel in the rice mills to generate steam for the parboiling process . This husk contains about 75 % organic volatile matter and the balance 25 % of the weight of this husk is converted into ash during the firing process , is known as rice husk ash ( RHA ). This RHA in turn contains around 85 % - 90 % amorphous silica.
Abstract--The experimental results on combustion of Rice husk in a lab scale fluidized bed combustor (FBC), using river sand as the bed material are presented in this paper. The Fluidized bed was operated at 15–25 kg/h of rice husk feed for various excess air factors (20-100%) and for the different fuel particle sizes. The effect of fuel feed
File Size: 881KB Rice husk has been used as a fuel to provide power for more than 100 years. The ˜rst recorded use of rice husk as an energy source was in 1889, in Myanmar. In the late 20th century rice husk’s potential as a fuel was recognized around the world, particularly in developing countries. In 1971, UNFAO stated that rice husk would become a key
The uses for rice husk are continually growing. Today it is increasingly used as biomass to fuel and co-fuel power plants. There are now many power plants in Asia powered 100% by ground rice husk. ricehusk.com Pte Ltd. is leading the introduction of rice husk into the EU biomass market.
File Size: 390KB Rice husk can be used as an alternative energy source, i.e. as the fuel in the boiler of a rice-milling kiln to generate electricity where the heating value of the husk ranges from 12.6 MJ/kg (Xu et al., 2012) to 13.34–16.20 MJ/kg (Mansaray & Ghaly, 1997) to 15.7 MJ/kg, of which 18.8% is carbon, 62.8% is volatile materials, and 9.3% is
2. BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction 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.
File Size: 274KB Rice. Rice is grown widely in tropical, temperate, and even in some cold zones. In the cleaning process, rice plant generates husks which are often burned afield or discarded. Thailand is the largest rice producer in the world, and a huge amount of rice husks are utilized as a boiler fuel.
The pressure difference in the chimney pulls air and fuel gas from the boiler or fireplace through the chimney and out of the building. Chimney Draft. The pressure difference or chimney draft can be expressed as: dp ch = h (ρ o-ρ i) a g (1) where. dp ch = pressure draft in the chimney (Pa) h = height of chimney …
Rice husk pellets as a biomass fuel will ease the environment pressures caused by fossil fuel combustion. Comparing with the burning of rice husk, the burning of rice husk pellets is much more clean. The ash content is around 15 to 16 % when burning directly which will be largely decreased to 6 to 7 % when it is burned in pellet form.
Combustion of Fossil fuel/Bio-fuel in Boilers is one of the proven methods for production of steam, required for the process in various types of industry. The running of Boiler with fuels of proper specification at a higher efficiency is the key to reduce the SOx, NOx& the PM levels in the stack which are the key air pollutants.
