Description
Technical field
The present invention relates to clean energy field, particularly relate to a kind of powder clean fuel.
Background technology
For a long time, as the topmost energy, coal supports the fast development of Chinese industrial, and the socio-economic development for China provides sufficient power.Meanwhile, the fossil oils such as coal, in the extensive use in the heavy industry fields such as steel-making, cement, electric power, metallurgy, also bring serious environmental pollution.Caused by the fossil energies such as continue the extreme haze weather occurred especially in recent years, its very important reason is just that China's energy structure is unreasonable, and clean energy consumption is less, long-term a large amount of use coals.
According to incompletely statistics, the existing Industrial Boiler of China 300,000, Industrial Stoves are at about 150,000, and within 2014, the annual coal that consumes is at about 4,000,000,000 tons.Consumption such as industry such as removing electric power, cement etc. occupies about 2,000,000,000 tons, and only about half of coal is used directly to the civilian loose burning of technical grade, and a large amount of coal causes multiple environmental pollution in combustion.Add up according to relevant scientific research institutions, in the atmospheric polluting material of China 87% SO
2, the flue dust of 79% and the VOC of 76% are directed to the burning of coal.
Along with industry, expanding economy, the water pollutions of China, topsoil, soil contamination problem are also further outstanding, and it is healthy that environmental pollution has now had a strong impact on China resident.In recent years, along with the appearance in succession of many environmental regulations, reduction is polluted, energy-saving and emission-reduction have become the state basic policy of China and the emphasis of enterprise work.Research and development clean fuel material, developing utilization of new energy resources also becomes current important scientific research trend.
Coal, biological material, as conventional fuel, can generate a large amount of CO during burning
