Description
в многозонных печах полукоксовани с внутренним обогревом в качестве теплоносител камеры полукоксовани примен ютс смешанные газы, т. е. смесь нродуктов горени обратного газа с избытком этого газа.In multizone semi-coking furnaces with internal heating, mixed gases are used as the heat carrier of the semi-coking chamber, i.e. a mixture of non-combustion products of reverse gas with an excess of this gas.
Педостаток способа заключаетс в том, что требуетс большое количество теплоносител , что вызывает чрезмерную загрузку газодувки и аппаратуры конденсацнн. Калорийность газа при этом низка, так как при горении с недостатком воздуха метан и непредельные углеводороды разлагаютс с выделепием сажистого углерода.The disadvantage of the method is that a large amount of heat transfer fluid is required, which causes an overload of the gas blower and the condensation apparatus. The calorific value of the gas is low, because when burning with a lack of air, methane and unsaturated hydrocarbons decompose with carbon black.
Предложенный способ отличаетс от известного тем, что в топку дл получени теплоносител подают газ и воздух в соотношении от 1 :3 до 1:4, что соответствует содержанию кислорода 10-12;)/о- При таком избытке воздуха и горении газа с калорийностью 1800-2000 кал/MS температура теплоносител достигает 900-1000°С. Теплоноситель поступает через колосники в зону полукоксовани , вызыва суш,ественную газификацию полукокса.The proposed method differs from what is known in that gas and air are supplied to the furnace to obtain a coolant in a ratio from 1: 3 to 1: 4, which corresponds to an oxygen content of 10-12;) / o- With such an excess of air and gas burning with a calorie content of 1800 -2000 cal / MS heat carrier temperature reaches 900-1000 ° C. The coolant flows through the grate into the semi-coking zone, causing sushi and natural gasification of the semi-coke.
Газы охлаждени , поступающие снизу, сгорают за счет кислорода теплоносител и поднимают температуру в камере до 1250- .The cooling gases entering from below are burned off by the oxygen of the coolant and raise the temperature in the chamber to 1250.
при необходимости эта температура снижаетс путем распылени воды в топке.if necessary, this temperature is reduced by spraying water into the furnace.
Предмет изобретени Subject invention
Способ получени теплоносител дл полукоксовани в многозонпых шахтных печах путем сжигани газа в токе воздуха, отличающийс тем, что, с целью повышени эффективности нроцесса полукоксовани , газ и воздух берут в соотношении от 1 :3 до 1:4.The method of producing heat carrier for semi-coking in multi-zone shaft furnaces by burning gas in an air stream, characterized in that, in order to increase the efficiency of the semi-coking process, gas and air are taken in a ratio from 1: 3 to 1: 4.
