What is 'WHITE COAL' ?

Answer 1

'''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. 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.

Answer 3

Let me paraphrase. It's basically charcoal, or wood, but it is not charcoal because it is not carbonized. So it's dry, chopped wood.

Answer 4

chalk

No idea man

Answer 6

What is White Coal?
• It is a coal substitute made from agriculture and forest waste.
• This white coal can be efficiently used to replace coal and fire wood.
• The fuel briquettes are converted from the agro waste to solid cylinder shape logs using very high mechanical pressure, without help of any chemical or binder.

Properties
• Consistent quality
• No pollution as it does not emit any sulphur or phosphorous chemicals.
• High caloric value ranging between 3600 to 4200 Kcals.
• Low ash contents as compared to steam coal to hard coke.
• Moisture contents nil because white coal is totally dry.
• Cheaper rates as against other fuels such as coal and fire wood.
• Efficient fuel ideally sized 90 mm Dia and 6” and 12” length.
• Easy for feeding due to its proper size for handling and does not stair cloths at all.

Benefits of White Coal against Conventional Coal
• There is no fly ash when burning briquettes.
• White coal is cheaper than heavy furnace oil, coal & fire wood etc.
• Combustion is more uniform compared to coal and boiler response to changes in stream requirements is faster, due to higher quantity if volatile matter in briquettes.
• Biomass briquettes have a higher practical thermal value and much lower ash content (2-10% as compared to 20-40% in coal).
• Briquettes have consistent quality, have high burning efficiency, and are ideally sized for complete combustion.
• Oil & Coal contains high sulpher which pollutes the environment.
