3, exhaust smoke exhaust fan speed smoothly, reduce the burning flame.4, combustion-supporting air leakage can be heat exchanger, avoid air exhaust fan away, influence of gas and air mixture combustion ratio.5, connecting flange of heat exchanger and leakage can be sealed, avoid cold air into the outside world, try to improve the combustion air temperature.6, if the conditions and funding allows cases, large heat exchanger should be installed, the use of emissions to the outside of the workshop of the waste heat (up to 390 ℃ preheat air for the first time, after the air into the burner of the radiation tube heat exchanger secondary preheated air, improve the combustion air temperature.7, radiant tube temperature > 400 ℃ (furnace temperature, it is forbidden to open the lid of the stove and remove the burner and heat exchanger, avoid high temperature contraction crack caused by radiation tube in cold air.8, try to arrange the heating demand the same strip concentrate production.9, production to maintain the uniformity of working temperature, avoid rapid heating burner and stop the burner work for purging cooling operation.
