Abstract
The invention provides an application of a synthetic fixed-form biomass fuel containing urban sludge components, which refers to that by a physical or chemical method, the urban sludge is utilized as main (minor) ingredient for synthesis with crop straws to produce biomass fuel with a fixed form which is used for boiler combustion for generating electricity or supplying heat. According to the shape and size of the biomass fuel, and by selecting a reasonable boiler structure and a proper combustion control mode or by combined combustion with other biomass straws, the stable operation of the boiler is realized, and steam is generated for electricity generation or heat supply when the biomass fuel with a fixed form is utilized. The application of the synthetic fixed-form biomass fuel promotes the harmless treatment of urban sludge, expands the source of biomass fuel used for generating electricity, and improves the development of green recycling economy.
Description
Technical field
What the present invention relates to is a kind of application of synthetic fuel, specifically, is a kind of application that contains the composite solid state biomass fuel of city sludge composition, belongs to the fuel field.
Background technology
1. China's regenerative resource developing goal with biomass energy as the field of determining in the planning of giving priority to, and the biomass utilization field with fastest developing speed be exactly biomass straw direct combustion power generation technology, from tens of families straw power generation enterprise practical conditions of present operation, there is the nervous problem of fuel supply mostly.2. the several hundred million tons of the annual generation of China city sludge, and urbanization speed are accelerated year by year, and urban population progressively increases, the quantity that mud produces is also increasing year by year, at present the means of Treatment of Sludge mostly are land-fill method, land occupation not only, and cause underground water pollution.Existing multiple at present with mud and the synthetic technology of producing biomass fuel of agricultural crop straw, but best application approach also do not found.3. at present the boiler of biomass fermentation group of motors adopts biomass straw direct combustion mode more, and the main source that acts as a fuel with biomass straw.Also adopt the mixed combustion mode of conventional fuels such as stalk and fire coal based on the unit of the little thermoelectricity transformation of routine, still be difficult to contain the fuel source of the composite solid state biomass fuel of city sludge composition as station boiler generating or heat supply.
Summary of the invention
At present existing several different methods is with mud and agricultural crop straw carries out physics or chemical method is synthesized the technology of producing solid-state biomass fuel, and the bonding and problem of solidification and the comburant pollution problem that have solved mud and agricultural crop straw; The generating or the design production unit of heating boiler have also solved in the mud harmful components to the etching problem of heating surface.
The present invention had both promoted to have solved the secondary pollution problem of effective handling problem, land seizure and the mud of city sludge, provide new fuel source for present biomass fermentation power technology again, the harmless treatment that has realized city sludge is docked with the two-way of biomass fermentation power technology, be that agricultural crop straw is handled the best combination of handling with city sludge, meet national utilization of new energy resources policy.
The technical solution adopted for the present invention to solve the technical problems
Utilization is synthesized and is produced the biomass fuel with solid form based on the method and the agricultural crop straw of city sludge (assisting) material composition by physics or chemistry, is used for boiler combustion generating or heat supply.
When utilizing the biomass fuel of these solid form, according to its shape and size, by select rational boiler structure, select suitably the burning regulative mode or with the mixed combustion of other biological matter stalk, reach stable operation of the boiler and produce steam-electric power or the purpose of heat supply.As, all can make the solid fuel of variable grain diameter be applicable to the boiler of different structure by the fire grate vibration frequency of adjusting water-cooled vibrations furnace grate or the chain speed of service of adjusting chain-grate boiler.
The specific embodiment
When the composite solid state biomass fuel that contains the city sludge composition was applied to the vibrations furnace grate of biomass power generation or heat supply unit separately or adjusts chain-grate boiler, its particle diameter size was consistent and should be between 20-150mm.And make the solid fuel of variable grain degree diameter be applicable to the boiler of different structure by the fire grate vibration frequency of adjusting water-cooled vibrations furnace grate.
When the composite solid state biomass fuel that contains the city sludge composition mixes the vibrations furnace grate that is applied to biomass power generation or heat supply unit or adjusts chain-grate boiler in the 20%-80% ratio with other biological matter stalk, its particle diameter size should be consistent with the stalk particle degree size of institute adapted, and its diameter should be between 30-60mm.
Beneficial effect of the present invention
1. expanded the national energy resource, if annual more than one hundred million tons city sludge is all for generating or confession Heat can be country and saves tens million of tons of raw coal, has reduced the CO2 emissions of electricity power enterprise, and is short Advanced the development of green circulation economy. 2. for living beings electricity power enterprise has widened fuel supply channel, slow Separated present biomass power generation enterprise ubiquitous fuel supply shortage situation. 3. utilize agricultural discarded The relevant preferential policy that thing (stalk), city sludge are processed can further reduce biomass power generation enterprise The fuel service cost, improve Business Economic Benefit. 4. the composite solid state that contains the city sludge composition is given birth to Material fuel is the formed solid biomass fuel of being mixed and processed by city sludge and agricultural crop straw Material has the long-distance transportation of being suitable for, is easy to the advantages such as storage and management, is adapted to electricity power enterprise to combustion The requirement of material. 5. China has the mud more than 60% to carry out landfill at present, and the present invention can promote Reduce the quantity of city sludge landfill, harmful substance is to the secondary pollution of underground water in the minimizing city sludge. Contain the composite solid state biomass fuel of city sludge composition on biomass power generation (or heat supply) boiler Application be that agricultural waste material is processed the best combination of processing with city sludge, it is new not only to meet country The using energy source policy, and efficiently solve the final handling problem of city sludge, solved the soil and accounted for With with the secondary pollution problem of mud.
Claims (2)
1. application that contains the composite solid state biomass fuel of city sludge composition.It is characterized in that: utilize city sludge to be master's (assisting) material composition, method by physics or chemistry and agricultural crop straw synthesize produces the biomass fuel with solid form, is used for boiler combustion generating or heat supply.
2. the application of composite solid state biomass fuel according to claim 1, when using the biomass fuel of these solid form, according to its shape and size, by select rational boiler structure, select suitably the burning regulative mode or with the mixed combustion of other biological matter stalk, reach stable operation of the boiler and produce steam-electric power or the purpose of heat supply.As, all can make the solid fuel of variable grain degree diameter be applicable to the boiler of different structure by the fire grate vibration frequency of adjusting water-cooled vibrations furnace grate or the chain speed of service of adjusting chain-grate boiler.
