Abstract
The invention relates to a sludge composite fuel and a processing method. Coal is the life blood for industrial and agricultural development. With the industrial and agricultural development, coal consumption is high. However, workable coal resources become less and less, coal demand becomes bigger and bigger, and the more the combusted coal is, the more the sulfur and carbon dioxide contained in the emitted flue gas are. Consequently, the atmosphere is polluted, the mankind is harmed and the research and the development of renewable energies and fuels are of great urgency. The sludge composite fuel is formed by the following raw materials in parts by weight: 20-40 parts of sludge discharged by sewage treatment plants, 60-40 parts of straw powder, 5 parts of cow dung powder, 5 parts of wood powder and 10 parts of combustion improver. The sludge composite fuel can be used for industrial boilers, power generation boilers, heating boilers for communities, bathing pools, agricultural heating, food cooking and the like.
