Description
Technical field
Pulverized coal boiler ignition of the present invention and smooth combustion apparatus and using method relate to thermodynamics mechanical device and using method technical field; Be particularly related to the thermodynamics mechanical device and the using method technical field of combusting coal fines; Relate in particular to the thermodynamics mechanical device and the using method technical field that adapt to various atures of coal; Be specifically related to pulverized coal boiler ignition and smooth combustion apparatus and using method 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 coal dust 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 pulverized-coal fired 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 pulverized-coal fired 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, for first kind of situation of pulverized-coal fired boiler, because it is an independent industry, just not saying temporary here.Second kind of situation for burner, the research work of being done is maximum, 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 the patent application of " 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 the patent application of " igniting lower resistance horizontal bias moulded coal powder burner ", application number is 2,007 2 0,152 107.3, name is called the patent application of " 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 the patent application of " 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 the patent application of " a kind of some meager coal/anthracite start-up burner " ... Deng.The third situation for burning torch, also carried out corresponding patent application, as application number be 20,071 0,110 800.9, name is called the patent application of " energy-storing pressure-stabilizing oil-supply device dedicated for gasified small oil gun ignition ", application number is 2,007 2 0,152 105.4, name is called the patent application of " energy-storing pressure-stabilizing oil-supply device dedicated for gasified small oil gun ignition ", and application number is 2,007 20,155 750.1, name is called the patent application of " a kind of Gasifying Small Oil Gun igniting flame image supervising device " ... Deng.For the 4th kind of situation of burner igniting, it is second corresponding comprehensive and complementary with the third situation, need not further to state at this.But, there are two kinds of situations to need explanation: first, the unicity defective of patent applied for technology, with regard to above-mentioned patent application and existing known technology, though they respectively have technical characterstic separately, can only be at the coal dust of its corresponding a certain ature of coal and use and integrate their existing a kind of technology, 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; Second, integral body light with combustion process in the science integrated of shortcoming complex art surely fire, as from blower fan to coal pulverizer with high tonnage, big heat energy, sufficient air quantity, continuously heat, certainly will cause great waste, the station of burner is single, can't according to circumstances carry out corresponding technical measures, and the waste heat of pulverized-coal fired boiler makes full use of inadequately ... Deng; Thus, its common deficiency, defective and drawback need not spoken more.
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 " electromagnetism ", " laser ", " integral body is surely fired ", " skilfully use heater between blower fan and coal pulverizer ", the key problem in technology of " whole using method ", developed the present invention's " pulverized coal boiler ignition and smooth combustion apparatus and using method ", thus, the present invention is exactly in conscientious and sufficient investigation, understand, analyze, sum up on the basis of above-mentioned existing known technology and present situation, have the deficiency that exists in known technology and the real current situation for overcoming and solving, defective and drawback are succeeded in developing.
