Description
газа с .коэффициентом расхода воздуха U. 1,02-1,05, а количество воздуха во вспомогательной смеси устанавливаетс из расчета сжигани газа с коэффициентом расхода воздуха о4 0,8. При этом соотношение расхода вспомогательной смеси к рабочей смеси 5%. Высокотемпературные химически активные продукты сгорани вспомогательной смеси, вытека из форкамеры со скоростью 200-3.00 м/с турбулизируют рабочую смесь на входе и горелочный туннель и повышают эффективность ее сгорани . Это позвол ет повысить температурный уровень и выровн ть профиль температур на входе продуктов сгорани в рабочую камеру печи.gas with an air flow ratio U. 1.02-1.05, and the amount of air in the auxiliary mixture is calculated on the basis of gas combustion with an air flow ratio of about 0.8. The ratio of the flow rate of the auxiliary mixture to the working mixture is 5%. High-temperature chemically active products of combustion of the auxiliary mixture, flowing out of the pre-chamber at a speed of 200-3.00 m / s, turbulize the working mixture at the inlet and the burner tunnel and increase the efficiency of its combustion. This makes it possible to increase the temperature level and equalize the temperature profile at the inlet of the combustion products to the working chamber of the furnace.
На режиме выдержки металла при заданной температуре печи расход природ- 20 ного газа, поступающего в. горелки, устанавливают 12 , а расход газа, поступающего в форкамеры, 3,6 . При этом соотношение расхода вспомогательной смеси к расходу рабочей сме- 25 си составл ет 30%.In the mode of holding the metal at a given furnace temperature, the flow rate of natural gas entering into. burners, set 12, and the flow rate of gas entering the prechamber, 3.6. The ratio of the flow rate of the auxiliary mixture to the flow of the working mixture is 30%.
