Description
Дл этого отношение расходов воздуха горени через пару противоположных горелок секции устанавливают обрат но пропорциональ ным от ношению расходов воздуха разбавлени .For this, the ratio of the combustion air flow rates through a pair of opposing burners of the section is set inversely proportional to the air flow rate of the dilution.
При работе обжиговой машины по показани м стационарных контрольно-Iизмерительных приборов находитс секци горна с парой противоположных горелок, разр жение в.которой меньше по сравнению с разр женем в соседних секци х. С нее и начинаетс регулирование теплового режима горна, так как перетоки избыточных продуктов сгорани , затрудн ющиеWhen the kiln is operating, the horn section with a pair of opposing burners is located on the indications of the stationary test-measuring devices, the discharge in which is less than that in the adjacent sections. The regulation of the thermal conditions of the hearth begins with it, since the overflows of excess combustion products, which impede

Регулирование ч;еплового режима в данной секции на первом этапе ведетс при равных отношени х топливо-топливо, топливовоздух дл пары противоположных горелок данной секции. После того,как температура секции выведена на заданный уровень, осуществл етс выравнивание температуры по ширине и расходов продуктов сгорани , поступающих через пару противоположных форкамер . the process of establishing a predetermined thermal regime is stressful from this section to the adjacent ones. The regulation of the heat regime in this section at the first stage is carried out at equal ratios of fuel-fuel, fuel-air for a pair of opposite burners of this section. After the section temperature has been brought to a predetermined level, the temperature is equalized over the width and flow rates of the combustion products supplied through a pair of opposite pre-chambers.

With other ratios of combustion air flow and high-temperature diluent, the symmetry of the combustion products through a pair of opposite

Then, each subsequent section is individually controlled as the discharge in the furnace increases.
Использование предлага:емого способа регулировани теплового режима в горнах обжиговых конвейерных машин дл термообработки окатышей обеспечивает выравнивание температурного пол газов по ширине горна и повышение средней температуры газов в горне , что в конечном счете повышает качество готовой продукции и производительность обжиговой машины.Using the proposed method for controlling the thermal conditions in the furnaces of calcined conveyor machines for heat treatment of the pellets aligns the temperature field of gases across the width of the hearth and increases the average temperature of the gases in the furnace, which ultimately improves the quality of the finished product and the performance of the kiln.
