Изобретение относитс к комбинированным печам и может примен тьс в цементной промышленности.The invention relates to combination furnaces and can be applied in the cement industry.
Известен способ управлени процессом обжига, включак дий в частное- 5 ти стабилизацию температуры воздуха, поступающего из холодильника Ij.There is a known method for controlling the burning process, including in particular stabilization of the temperature of the air coming from the cooler Ij.
Недостатком его вл етс то, что при этом не учитываютс подсосы холодного воздуха с гор чего обреза пе-10 чи, измерение температуры воздуха, выход щего из холодильника, вл етс неточным.The disadvantage of it is that it does not take into account cold air inflow from the hot edge of the fire, measuring the temperature of the air leaving the refrigerator is inaccurate.
Наиболее близким к изобретению по |5 технической сущности и достигаемому эффекту вл етс способ управлени процессом обжига клинкера во вращающейс печи с колосниковым холодильником , включающий измерение расхода 20 гор чего воздуха в печь из холодильника и расхода холодного воздуха в печь 2.The closest to the invention according to the technical essence and the achieved effect is a method of controlling the clinker burning process in a rotary kiln with a grate cooler, including measuring the flow of hot air 20 into the kiln from the cooler and the flow of cold air into the kiln 2.
Недостатком этого способа вл етс сравнительно низка эффектив- 25 ность управлени процессом обжига ввиду сложности и невысокой точности измерени температуры воздуха, подаваемого в печь из холодильника, а также отсутстви учета подсосов хо- 30The disadvantage of this method is the relatively low efficiency of the control of the firing process due to the complexity and low accuracy of measuring the temperature of the air supplied to the furnace from the refrigerator, as well as the absence of accounting for the suction
