approximately 1 mm in size can easily be used as fuel. A coal mill is retrofitted as a woody pellet mill, and the pellets are crushed and sent to the multi-burner via each fuel pipe by air in the same way as pulverized coal. If the particle size of the fuel sent to the burner is 1 mm or more, the combustibility in the boiler will deteriorate.

Coke (fuel)

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term coke usually refers to the product derived from low

Carbon Dioxide Emission

Environmental emission of carbon dioxide CO 2 when combustion fuels like coal, oil, natural gas, LPG and bio energy. To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) - 44 / 12 = 3.7.
