Problems solved by technology

[0003] At present, the general treatment method for solid waste with calorific value is incineration, which needs to be carried out in a dedicated incinerator. On the one hand, the incinerator equipment used for incineration is complicated, and the operation and maintenance costs are high, which increases the cost of waste treatment. On the other hand, incineration of those wastes with low pollution factors and calorific value not only increases the cost of incineration but also causes a waste of resources

Abstract

The invention relates to the field of solid fuels, and discloses a novel solid regenerated fuel, which comprises solid wastes and additives, wherein the solid wastes have the heat value no more than 2,500Kcal / Kg and pollution factors less than 5. The raw materials are mainly the solid wastes with certain heat value and less pollution factors; according to the used solid wastes, the additives are selected; the prepared novel solid regenerated fuel has stable properties, is easy to store and transport, can be mixed with other fuels, generates a little ash after combustion, meets the combustion requirement of fuels, and ensures the heat value of more than 3,000Kcal / Kg; and waste gas generated after combustion can meet the integrated emission standard of air pollutants. The novel solid regenerated fuel has great environmental protection significance and energy conservation and emission reduction significance.

Description

technical field [0001] The invention relates to the field of solid fuels, in particular to solid regenerative fuels; in addition, the invention also relates to a method for preparing solid regenerative fuels. Background technique [0002] At present, the fuels used by countries all over the world are almost all fossil fuels, namely oil, natural gas and coal. The fossil fuels that have been gradually formed by nature over millions of years may be completely exhausted by humans within a few hundred years. According to investigations and studies, there is no coal and oil forming underground today. In 2008, in the face of the international oil price exceeding USD 150 per barrel for the first time and the increasing pressure on energy conservation and emission reduction, energy issues have once again become the focus of attention of the world. [0003] At present, the general treatment method for solid waste with calorific value is incineration, which needs to be carried out in...
