Description
Technical field
The utility model relates to the comprehensive coproduction of bituminous coal and utilizes system, is specially a kind of novel bituminous coal conny and transforms anthracite briquette and generating, coal gas, tar, preheating coproduction utilization system.
Background technology
China is that coal second reserves big country and first consumes big country in the world.Explored coal reserves more than 9,000 hundred million tons, wherein hard coal (fugitive constituent <10%) accounts for 10%, brown coal (fugitive constituent >40%) account for 15%, bituminous coal (wherein 80% is conny) accounts for 75%.The coal consumption of China accounts for more than 75% of total energy consumption, wherein hard coal because thermal value is high, fugitive constituent is low, burning is without advantages such as black smoke pollutions, be widely used in the fields such as industrial gas, chemical fertilizer synthetic ammonia, domestic fuel (food and drink, heating, bathing), but its year produced quantity can only satisfy the demands 1/3, breach is huge, and bituminous coal can only be utilized to carry out Some substitute; Brown coal thermal value low (most <3000 kilocalorie), water content high (15%-60%), need drying to dewater and improve calorific value (>4500 kilocalorie) to utilize afterwards.Brown coal easy-weathering spontaneous combustion in addition, limits its long-distance outward transport and market sale, can only develop nearby; The bituminous coal accounting for coal exploitation proportion maximum is widely used in iron and steel, building materials, Coal Chemical Industry (accounting for 20% altogether), thermal power generation (accounting for 70%) and alternative domestic fuel (accounting for 10%).Bituminous coal (iron and steel, building materials, the civilian and generating) Land use systems of China is Direct-Combustion Technology, and there is the problems such as resource utilization is low, seriously polluted, Coal-fired Thermal Power industry is wherein the most outstanding.
Bituminous coal utilizes rich and influential family---coal-fired thermal power generating technology present situation
Ye Shi thermal power generation big country of China, the energy structure based on coal, determines China with the dominant position of coal fired power generation.The coal-fired thermal power generation installed capacity of China, accounts for all installation 67% of total amount and 92% of thermal power generation total amount respectively.Coal-fired thermal power generation generally adopts direct combustion power generation technology, and operational path is: bituminous coal is milled to 200 order coal dusts, blows and is mapped to boiler combustion, and the water in heating boiler becomes water vapour, and pushing turbine generates electricity.Coal direct combustion power generation technology has the advantages such as investment is little, cost is low, but there is the large drawback of resource waste and pollution environment two.One is that the coal tar be rich in coal is burnt in vain, both causes the wasting of resources, and exacerbates again two secondary environments; Two be coal directly burn produce and discharge a large amount of noxious fume and obnoxious flavour.According to statistics, in China's air flue dust 70%, sulfurous gas 90%, 70% of carbonic acid gas, 67% of oxynitride all comes from the discharge of burning, the contribution degree of wherein thermal power generation is up to 80%.Therefore, the emphasis of control atmosphere pollution and key improve bituminous coal combustion, especially thermoelectricity coal combustion technology, while raising efficiency of combustion, significantly reduces generation and the discharge of pollutent.
Clean coal technology is the dominant technology that our times various countries solve environmental problem, the key areas of the international hi-tech competition of Ye Shi.The representative technique studying thermal power generation clean coal technology on probation at present is both at home and abroad: " integrated gasification combined cycle for power generation system (IGCC) ", its technological process is: bituminous coal is through being gasificated as middle low-heat value gas, through purification, the pollutent such as sulfide, nitride, dust in removing coal gas, become clean geseous fuel, be sent to gas turbine power generation, the exhaust of internal combustion turbine enters waste heat boiler heated feed water, produces superheated vapo(u)r and drives steam turbine generating.IGCC technology is efficient combustion gas---and steam association circulating power generation system and clean Coal Gasification Technology combine, both generating efficiency was improved, energy-saving and emission-reduction again, the net efficiency of its generating can reach 45%, desulfuration efficiency can reach 90%, sulfur dioxide emissions, discharged nitrous oxides, pollutant emission and water loss, only have 2% of conventional coal-burning power plant, 20%, 10% and 30% respectively.But with high investment, high cost and the rigors etc. of vapourizing furnace to raw material limit applying of IGCC technology.Typical case is: at present China only has Tianjin, Huaneng Group IGCC mono-to test power plant, and its construction scale is 250,000 kilowatts, investment intensity be 1.3 ten thousand yuan every kilowatt developed countries such as (be 0.8 ten thousand yuan) Japan; Cost of electricity-generating is 0.9 yuan/degree (rate for incorporation into the power network is 0.5 yuan/degree), if long-time running is monthly lost can reach 100,000,000 yuan.On the other hand, IGCC can the working condition of matching used three kinds of vapourizing furnaces be respectively: one is that the furnace temperature of fluid injected bed vapourizing furnace can reach 2000 DEG C, has burnt the coal tar of high value, has caused the wasting of resources; Two be fixed-bed gasification furnace (lurgi gasifier) though recyclable coal tar, but High Quality Tobacco coal cinder coal can only be used; Three is that fluidized-bed gasification furnace can the organism such as more recovery tar and hydrocarbon, phenol, benzene, naphthalene, but also must use bituminous coal lump coal, and the conny accounting for bituminous coal 80% can not directly use equally.
Therefore, a large amount of bituminous coal connys is made anthracite briquette, simultaneously supporting solution high-temp combustion hot strength, reclaim coal tar, remove the corresponding technology problems such as pollutent, and be widely used in the fields such as thermal power generation, industrial gas, domestic fuel, chemical fertilizer synthetic ammonia, be take into account the key point realizing improving the level of resources utilization and energy-saving and emission-reduction dual core target.
