Description
Technical field
The present invention relates to moulded coal field, particularly a kind of moulded coal containing biomass fuel.
Background technology
Moulded coal take fine coal as main raw material, by the machined compression moulding of proportioning, physical strength and shape size required by concrete purposes, has some strength and size and different coal finished product; Moulded coal has that technique is simple, less investment, cost are low, and can obtain and promote coal-fired quality, improve efficiency of combustion, reduce the advantages such as coal burning pollution, is therefore used widely in people's daily life and industrial production as fuel.But coal resources are fewer and feweri, people start more and more to focus on waste resource to be applied in moulded coal, develop economic model capable of circulation.
In China's sugar industry production process, all inevitably produce the waste pollutants such as the very huge filter mud of quantity, waste molasses and sugarcane marrow every year.Wherein except sugarcane marrow is used (on a small quantity as paper making raw material, other are as boiler oil), other wastes are all less than effectively being utilized, only make some halfway environmental protection treatment, direct discharge, sugar enterprise takes huge expenses of environmental protection, does not produce any economic benefit, and can only process about 1/3 of existing waste pollutant.
In rural area, the agriculture and forestry organic waste materials such as stalk, bark, straw, only have a small amount of for pasture; or be used as farmland fertilizer; but still have a large amount of more than needed, if can filter mud, molasses and agriculture and forestry organic waste material be applied in moulded coal, will to realizing resource circulation utilization, preserve the ecological environment significant.
Summary of the invention
The invention provides a kind of moulded coal containing biomass fuel, adopt filter mud of sugar refinery, biomass fuel as moulded coal raw material, achieve the recycling of waste resource.
