Description

вышающей температуру плавлени  шлака. Наход щиес  в дымовых газах частички расплавленной золы и шлак сепарируютс  в верхнем участке 5 капала 1 па поступающий из циркул пиопной трубы 2 шлак. В нижней части верхнего участка 5 канала 1 щлак, движущийс  по каналу 1, расплавл етс  теплом дымовых газов, в впде капель вытекает через решетку 11 и нижний участок 7 капала 1, где охлаждаетс  воздухом , и в виде твердых грапул поступает в бункер 4. Часть щлака в количестве, равном количеству золы, поступающей с топливом в топку 6, выводитс  из бункера 4 через патрубок 10 в отвал.the melting point of the slag. Particles of molten ash located in the flue gases and slag are separated in the upper section 5 and 1 drop of slag coming from the circulating pipe 2 of the pipe. In the lower part of the upper section 5 of channel 1, slag moving through channel 1 is melted by the heat of flue gases, flows out through the grid 11 and lower section 7 drops 1, where it is cooled by air, and in the form of solid grapes enters the bunker 4. Part slag in an amount equal to the amount of ash supplied with the fuel to the firebox 6 is removed from the hopper 4 through the nozzle 10 to the dump.

Применение в качестве промежуточного теплоносител  щлака топлива позвол ет исключить из процесса применение дорогосто щего и дефицитного огнеупорного материала , что повышает экономичность.The use of fuel as an intermediate heat carrier of scrap metal makes it possible to exclude the use of expensive and scarce refractory material from the process, which increases efficiency.

Подача дымовых газов в капал 1 с температурой , превыщающей температуру шлака , обеспечивает высокую степень очистки дымовых газов от золы п шлака, позвол ет отказатьс  от газоочистительпых устройств , что также повышаетэкономичность.The supply of flue gases to the drip 1 with a temperature exceeding the slag temperature provides a high degree of purification of the flue gases from the ash of the slag, and allows refusing the scrubbing devices, which also increases the cost-effectiveness.
