Description
Technical field
Electromagnetic heating type combusting device of the present invention relates to thermodynamics mechanical device technical field; Be particularly related to the thermodynamics mechanical device technical field of combusting coal fines; Relate in particular to the thermodynamics mechanical device technical field that adapts to various atures of coal; Be specifically related to the electromagnetic heating type combusting device technical field.
Background technology
China is maximum in the world coal production state and country of consumption, and coal accounts for about 75% of China's energy demand total amount at present, well beyond 27% world average level; Therefore, particularly important for making full use of concerning China of coal.At present, process of consumption for coal, the subject matter that exists is: one is the kind difference of coal, the coal of different cultivars has different characteristics, as Datong District's piece, anthracite, brown coal, meager coal, deep or light moulded coal ... wait the meager coal of each kind, rich coal, big moisture coal, little moisture coal, volatile coal, not volatile coal, big viscosity coal, little viscosity coal ... coal etc. various grades and situation, inherent characteristic is separately all arranged, thereby cause the requirement of the igniting of matchmaker's powder and burning also differently, otherwise will make igniting produce difficulty, and cause difficulty for follow-up burning; The 2nd, incomplete combustion, unfavorable just because of igniting, thus cause subsequent combustion incomplete, owing to incomplete combustion causes to the waste of the energy with to the pollution of environment; The 3rd, unburnt coal dust particle produces adherent incrustation phenomenon near the internal face port and the port, thereby causes the generation of slagging scorification and high temperature corrosion, has influenced the service life of burner to the utmost; This situation is for generating plant pulverized coal boiler and various pulverized-coal fired boiler, and its situation is particularly outstanding.
Be more specifically to the pulverized-coal fired boiler in power station, China also exists idea and reality different and difference in essence with world developed country: the pulverized-coal fired boiler in world developed country power station is certain, under this fixing pulverized-coal fired boiler prerequisite, select to adapt to the coal dust that this coal powder boiler combustion requires, to reach the purpose of high-quality burning.And the situation of China is just different, though the pulverized-coal fired boiler of China is also fixed, is not according to boiler coal separation powder, but has the coal dust of sample to burn which type of coal dust; Be purpose to reach the high-quality burning equally, this just needs us to carry out deep research and developing.
With regard to the national conditions of China, qualitative and diversity categories of coal of matchmaker's powder boiler is the present situation and the prerequisite of the present national conditions of very important and mandatory China; So, need research a lot of round national conditions with the problem of developing, generally be divided into following several big class: the one, on matchmaker's powder boiler, make an issue of; The 2nd, on burner, make an issue of; The 3rd, on burning torch, make an issue of; The 4th, in the igniting of burner, make an issue of; Four complement each other, emphasize particularly on different fields, indispensable.In four kinds of above-mentioned situations, maximum for the research work that second kind of situation of burner done, and all carried out patent application, as: application number is 2,004 2 0,115 242.7, name is called the patent application of " internal air film circumferential air type coal burner ", application number is 2,004 2 0,115 868.8, name is called " some coal dust with diesel oil or fuel gas ceramic burner tube ", application number is 2,007 2 0,152 106.9, name is called " igniting lower resistance horizontal bias moulded coal powder burner ", application number is 20,072 0,152 107.3, name is called " the some brown coal preposition air distribution start-up burner of lower resistance ", application number is 2,007 2 0,152 108.8, name is called " with the start-up burner of big cambered surface swing temperature adjustment ", and application number is 2,007 2 0,152 109.2, name is called " a kind of some meager coal/anthracite start-up burner " ... Deng.But, with regard to above-mentioned patent application and existing known technology, though they respectively have technical characterstic separately, and integrate their existing common deficiencies, defective and drawback are: a kind of technology can only be at the coal dust of its corresponding a certain ature of coal and is used, this is for the simultaneous national conditions of the multiple ature of coal of China, implementing will inevitably be owing to the burner of changing the relevant art feature because of the variation of ature of coal, thus, they exist the single limitation of technology, change the frequency sex change of the technology of changing with ature of coal, the loaded down with trivial details property of replacing technology, the broad spectrum activity that does not possess extensive adaptation ... Deng common not enough, defective and drawback.
Based on applicant and designer's professional knowledge inside information be engaged in industry work for many years enrich practical experience and to the excelsior pursuit of cause, from meeting the actual national conditions of China, to take the key problem in technology of " electromagnetism heating ", developed " electromagnetic heating type combusting device " new product, thus, the present invention is exactly on the basis of conscientious and sufficient investigation, understanding, analysis, the above-mentioned existing known technology of summary and present situation, for overcoming and solving that the deficiency, defective and the drawback that exist in existing known technology and the real current situation succeed in developing.
