The Research Of Theory And Application About New Burner With Low Pollution For Kiln

While the cement produces, more than 80% of energy was offered by the coal burner, so coal burner in law resolve kiln system occupy important position, extremely in advance person who burn, technical feature its index influence whole grog forge energy-conserving profit to cook system abolish, grog produce quality, refractory brick service time and turning round rate of system directly, and externality systematic craft accident and environmental quality. The burning device only with fine performance is combined with rational working parameter, could guarantee to feed and enter the fuel of systems of kiln to mix with the air two times of high temperature rapidly in burning the space, break out fire and totally burn in time, and offer sufficient heat as requested, form a rational temperature field and thermal technology system, thus make the system of rotary kiln give full play to its due function, realize the high-quality, high-efficient, low consumption, operating safely for a long time, respond to the request that environmental protection stipulates.Subject this is it solve design and, various kinds of test difficult problem was solved by that exist in using of burning etc. to aim at, through carrying on the cool and hot numerical simulation to the burning device, the structure to the burning device proposes improving, combine project that cement produce go on reasonable use to the burning device actually at the same time, in order to achieve and save energy and reduce the cost, reduce the purpose of pollution.The research contents of this project are divided into two parts altogether: Project application study of the research and burning device of the numerical simulation, burning device of the burning device.FLUENT, present prevailing hydro mechanical software of business computing software was adopted in Numerical simulation work. FLUENT co. of U.S.A., -FLUENT and deal with software pre- and post- fonning a complete set, production line cool is it is it imitate to go on to run actually while being heating to cement in 5000t/d of burning etc., systematic research to craft adaptability and formulation mechanism and control technology of NOx of production thereupon of parameter, coal of powder each chunnel of function and burning devices of burningetc..The development of the burning device adopts the combustion Tec of the swirl and bad fluidics of the large speed mainly, on the premise of emphasizing big thrust of the burning device, reduce every chunnel of wind amounts, improve speed of tunnel, is it suck to high temperature two one of wind to improve on one hand, improve the utilization ratio of heat, favorable to the burning of inferior anthracite and high volatile matter coal at the same time. The project application study of the burning device applies the burning device developed to project reality, including adjust craft parameter ,etc., and it with burning device compare with originally, in order to draw the real operation index, carry on constant optimization and improvement to the burning device. Indicate through the operation result of real factory of 6 months: Originally the burning device can replace the foreign like product, is superior to the foreign products in a situation that use high ash content coal and anthracite.
