<TD&nbspclass=z11&nbspheight=25> one, the disappear smoke of kiln of industrial boiler furnace removes dust the boiler of coal fired industry of     our country, main component is boiler of production of capacity ≥ 1t/h, heating; The tea bath furnace with quantity wide bedding face, Gong Fuzao reachs the cooking kitchen range of the innumberable families; Industry produces kiln heat.  1. This part boiler is boiler of the production of ≥ 1t/h, heating commonly mechanical combustion means, combustion is complete, caudal installation removes dust equipment. Below good in moving management case, can achieve content of national boiler air pollution to discharge a standard. Among them the coal fired boiler of 1 ~ <10t/h, use multibarrel tornado dust catcher more, remove dust efficiency is in commonly 95 % of 90 % ~ , to subtle dust classification efficiency Dc50 is controlled in 5 μ M; The coal fired boiler of ≥ 10t/h, use dust catcher of film of the water in grave of hemp stone article more, remove dust efficiency is in commonly 95 % above, to subtle dust classification efficiency Dc50 is controlled in 3 μ M. Bath furnace of  2, tea, Gong Fuzao, kitchen work is civil these cooking range measure small coal furnace bedding face is wide, it is low chimney is discharged, boiler combustion efficiency is low. In last few years, these small cooking range, change fuel structure is used to reach in big city change burn model coal, reduced contaminant greatly discharge. But be in in a wide place in the road, especially country, civil heating, cooking still is lighted directly with raw coal, contaminant discharges chroma tall.  3, industrial furnace kiln basically is used at heating, forging, stoving, molding sand, burn furnace for the hand more, because this is in phase of fire of coal, disclose, black smoke billow. Although the respect was transformed to do in structure of the sources of energy,work in great quantities in last few years, but be in a lot of areas, the smoke evacuation chroma of kiln of this part furnace is big, blackness is in Lin Geman 2 class above, still wait for development kiln furnace urgently to pollute processing equipment. 2, to decoke of industrial boiler flue gas is passed " 95 " tackle key problem project, promoted the further progress of technology of to decoke of flue gas of boiler of our country industry. "Wet desulphurization removes dust craft and equipment research " it is to be aimed at our country medium or small bedding face of quantity of coal fired boiler is wide, light opposite sex of the differentia that use coal be quality of environment of air of city of influence our country is big, main the project of science and technology that pollute the current situation of the source and develops. It is to be in " 85 " the seriation product of 5 kinds of model that development studies on the foundation that science and technology tackles key problem and craft of typical to decoke, already got applied in the project. Have suitable scope stability of wide, function, investment runs cost low characteristic, the grey water pollution that solved home to exist generally at the same time water of tape of shorter, equipment mixes water system, service life badly the general character problem such as dirty of easy knot of system of calcium radical to decoke. Its whole considers to provide international advanced level, win Chinese patent 4, it is a practical technology that fits our country national condition. Current, the coal fired boiler of our country <10t/h uses high grade coal and rear more technology of wet and simple and easy to decoke, high grade coal contains sulfur <0, 5 % , ash content is controlled in 10 % , efficiency of simple and easy to decoke is in commonly 50 % of 30 % ~ ; The coal fired boiler of ≥ 10t/h uses dust catcher of to decoke of film of hemp stone water more, desulphurization efficiency is in commonly 60 % of 30 % ~ , remove dust efficiency is in 96 % above. 3, sulfur of  1 of utility boiler to decoke, 2 oxidation is discharged reach our country of contaminative current situation discharge capacity of 2 oxidation sulfur occupies world first place, already exceeded 20 million tons for years continuously, power plant of its medium baking temperature discharges 2 oxidation sulfur to be close to the 50 % of gross, two control an area the 60 % that discharge capacity of 2 oxidation sulfur occupies gross. Our country acid rain and pollution of 2 oxidation sulfur are serious, acid rain area has occupied the 30 % of land area, acid rain and pollution of 2 oxidation sulfur cause pecuniary loss to be in every year 100 billion yuan of above. The characteristic of structure of our country the sources of energy decided to control coal fired of 2 oxidation sulfur discharging is the key that our country controls 2 oxidation sulfur to pollute, and control ammunition power plant discharge capacity of 2 oxidation sulfur is control coal fired the key that 2 oxidation sulfur pollutes. At present our country basically was used use low sulfur coal, close stop group of small fire electric machinery and partial ammunition power plant to install the measure such as device of flue gas to decoke to control igneous power plant 2 oxidation sulfur is discharged, use low sulfur coal among them contribution is the largest. Stand decision of our country national condition, 2 oxidation sulfur contaminates power plant of prospective control ammunition the mainest method is flue gas to decoke. But so far, our country has design of to decoke of flue gas of aircrew of above of 200 thousand kilowatt and capacity of equipment whole set not completely still. Because technology, economy reachs the reason of the respect such as policy, at present project of to decoke of our country flue gas already threw the igneous power plant that run to act aircraft total capacity just 510, 50 thousand kilowatt, take installed capacity of countrywide ammunition power plant only 2, 1 % , progress of project of to decoke of flue gas of igneous power plant is slow. Concern desulphurization technology policy of the branch according to experience of international of flue gas to decoke and country, the technical course of to decoke of flue gas of prospective our country is with wet desulphurization is given priority to, other method is complementary. Industry of to decoke of flue gas of igneous power plant has a few typical features: Desulphurization investment, moving cost is high, and main income is environmental benefit; The policy that belongs to a model guides model industry, the country has tremendous effect about policy. Home is at present  2, main enterprise of flue gas to decoke (1) Long Yuan environmental protection (country electric electric power) the limestone that introduced rice of German place calm to force a company - gesso is wet desulphurization technology. The company participated in demonstrative project of collaboration of many China and foreign countries early or late, if the Shandong of Sino-Japanese collaboration is yellow insular power plant and Taiyuan are the first heat and power plant, medium the Chongqing power plant of heart collaboration, Zhejiang the demonstrative project such as power plant of half hill power plant, Yunnan Xiaolong pool, relatively lead position is in in desulphurization domain. Dragon source environmental protection contracts always in June 2001 Beijing Beijing can pyroelectricity joint-stock company 4 furnace (200MW) desulphurization transforms a project, it is the desulphurization project that company first time contracts to do a job completely independently. (2) the mainstay business that Zhejiang humble amounts to Zhejiang humble is domain of electric dust catcher, the company is contributive many yuan 3000 introduce report of ABB company carry on one's shoulder to do to decoke of law flue gas from Sweden (NID) law, and complete one Taichun unit (aircrew of 70MW of power plant of provide for oneself of company of industry of chemistry of Zhejiang huge city) desulphurization project, run in order at present. The field is treated in flue gas as a result of the company old, have quite experience, make progress in domain of flue gas to decoke plus the company faster, because this is in this domain is integrated competition ability is stronger. (3) Long Jing environmental protection the key mainstay business that this company is industry of our country environmental protection, before ranking industry of electric dust catcher 10 strong, handle in flue gas (remove dust) the respect has rich experience. Dragon only environmental protection plans to use new a collect capital 1, industry of to decoke of flue gas of 62.4 billion yuan of investment, at present technical collaboration just is American GE company. Firm of energy-saving investment of dragon only company and China is joint-stock establish limited company of engineering of Long Jing to decoke of city of Fujian Province Longyan, register capital 39.6 million yuan, the company holds a scale to be 80 % . Company of dragon clean to decoke basically is engaged in desulphurization, remove dust the design of equipment is made, advisory service and project contract business, assuming special fund built national debt 1999 flue gas of coal fired power station removes dust desulphurization device is homebred turn a project. Dragon only environmental protection still is in the early days of transfer of technology of flue gas to decoke at present. (4) triumphant enlighten power company investment introduces RCFB 49 million yuan from German WULL company - technology of to decoke of flue gas of FGB dry method, production and stand-alone the desulphurization device of the utility boiler form a complete set under 300 thousand kilowatt, have the first whirl of domestic that has all and own intellectual property sparge is dry test facilities of to decoke of law flue gas. On July 19, 2000 triumphant enlighten the base of property of environmental protection of to decoke of Wuhan city flue gas that 6 units such as electric power form jointly hangs out his shingle formally hold water. At present announcement plans to add hair is new introduce wet desulphurization technology, this will enlarge a company to carry on the limits of domain of flue gas to decoke. (5) 9 dragon electric power advocate battalion power production and electric power technology serve. The company is passed new capital accuses a collect Yuan Dahuan protects a Chongqing (group) company (register capital 50 million yuan) enter industry of flue gas to decoke, those who use is the limestone that 3 water chestnut of Japanese are versed in again - gesso is wet desulphurization technology, carry out the organization the state committee of planning (plan high skill [1999]1297 sign language) the total investment of make known to lower levels is 1, 6.5 billion yuan " project of demonstrative project of technology of flue gas to decoke and industrialization of device high-tech technology " . (6) Tsinghua provides the fluid-bed of loop doing type that has intellectual property oneself with square company technology of flue gas to decoke, this technology applies to the aircrew under 300MW, the flue gas to decoke that applying at power plant of Tsinghua university experiment at present sets an example project. The company still developed to decoke of flue gas of fluid column eject to remove dust compositive technology, the flue gas to decoke that applies at Shenyang fertilizer total plant at present sets an example project. Pass 3 months debug move, had passed the appraisal of concerned branch. From state of progress of technology of each company to decoke, and the latent capacity of market of to decoke of prospective development flue gas undertakes integrated grading, because get national power company supports energetically, at present dragon source environmental protection has actual strength most in industry of flue gas to decoke. </TD></TR></TBODY></TABLE>
