white coal project report pdf
White coal is a form of fuel produced by drying chopped wood over a fire. It differs from charcoal which is carbonised wood. White coal was used in England to smelt lead ore from the mid-sixteenth to the late seventeenth centuries. It produces more heat than green wood but less than charcoal and thus prevents the lead evaporating.[1] White coal could be used mixed with charcoal for other industrial uses than lead smelting.[2] White coal was produced in distinctive circular pits with a channel, known as Q-pits. They are frequently found in the woods of South Yorkshire.
Nowadays white coal is made from
Groundnut shells
Cotton hulls and salks
Castor seed shells
Forest leaves; wood chips and shavings
Sugarcane bagasse
Rice husk and paddy straw
Mustard waste
Coir dust
Coffee husk
Sunflower waste
Maize stalks
Bajra cobs
Sesame seeds oil cake
Wheat straw
Benefits of white coal:
White coal is cheaper than coal and fire wood. There is no sulphur in the white coal, therefore no toxic gases.
Moisture content is nil. Biomass briquettes have a higher practical thermal value. Briquettes have consistent quality, have high burning efficiency, and are ideally sized for complete combustion. Combustion is more uniform compared to coal and boiler response to changes in steam requirements is faster, due to higher quantity of volatile matter in briquettes. Low ash contents. The calorific value of the finished briquettes is approximately 3500 to 4000 kcal/kg.
India is fast becoming a major manufacturer and consumer of white coal. A large number of companies have switched their boiler fuels to use white coal instead of fossil fuels. White Coal manufacturing capacity is coming up in droves in the state of Gujarat, Maharashtra, Tamil Nadu and Rajasthan.The production of White coal (Briquettes made of Biomass) using agricultural and forest waste is more common in North India
The White Coal Technology Process
White Energy s BCB technology upgrades sub-bituminous coals through a relatively simple thermal drying process followed by physical and chemical stabilisation through a novel binderless briquetting process. White Energy s BCB technology has been shown to be cost and operationally superior to competing processes and enables the commercial exploitation of a large number of low quality, high moisture coal deposits. White Energy s coal upgrading process provides coal fired power stations and other industrial applications with an opportunity to burn a cleaner and more efficient fuel.
White Coal is a very much in demand as an alternative fuel as it is pollution free. We are a leading Manufacturer and among the major Suppliers of White Energy Coal. In India, White Coal is used as a substitute for other fuels like coal, wood log or petroleum. This is very advantageous over the other fuels because of several reasons. They are economic and less costly. Easily transportable, white coal leaves with low ash. White Coal contains high density and higher fix carbon value which makes it more inflammable. Growing crisis and the price of the fossil fuels have made it an essential one.
We are glad to introduce our self as a leading manufacturer of biomass fuel,(used in shape of briquette) in our kota region.
Cleaner Atomosphere Greener Earth
Non pollutig - no sulfur.highly combustionable uniform energy,higher quantity of volatile material renewable energy.it gives much higher boiler efficiency compared to firewood or loose biomass because of lower moisture.,higher bulk density and lower ash content. biomass fuel is a forth coming fuel of the world.its use will suit towards economical,ecological and advanced environment company policy.biomass fuel,produced from bio wastes, generated every year with agricultural crops, is an ideal future fuel.
