It is discovered that the combustion condition of the second stage pc is up to the outlet temperature of the first stage pc and the content of combustible gases in first stage flue also plays positive effect on the ignition of second stage pc. the effects of parameters of two coal - air mixture, wall temperature of first ignition chamber and annular filling air on imfit are studied experimentally in this thesis. in this thesis, the numerical simulations of ignition and combustion of pc in imfit are conducted
本文通過建立數學模型，對感應加熱煤粉多級無油點火進行數值模擬，研究了一級煤粉煤粉在點火室內的著火過程和二級點燃過程、煤粉粒徑分佈對煤粉多級無油點火的影響，研究了一級點火室壁面溫度、一級煤粉氣流和二級煤粉氣流的風粉參數在煤粉多級無油點火過程中的影響規律；根據二級點燃段的流場和溫度場分佈，研究了環形夾心風推遲二級煤粉著火的機理。 -

Abstract : during the reduction of iron ore - coal pellet in air, the combustible gas generated from the reduction in pellet is burnt onto the firing surface around the pellet. between the pellet surface and the firing surface, ther e is such mixing gas containing the combudstible gas and burnt gas. it m ay b e sure that the iron ore - coal pellet is no oxidized in the week oxidizing atmos phere. the heat released by combusition on the firing surface is fast tranfered i nto the pellet, and the self - heating reduction of iron ore - coal pellet may occu r
文摘:鐵礦-煤球團在空氣中能夠還原的原因是：從球團排出的可燃性氣體在球面附近的火焰面上燃燒，在火焰面內側是氧化性較弱的可燃性氣體和燃燒產物的混合物，鐵礦-煤球團在弱氧化性氣氛中具有抗氧化性；在火焰面燃燒放出的熱量向球團傳遞，進行自熱還原 -
