Increase furnace ventilation rate of the method are: give full play to the suction force exhaust equipment and system to reduce the resistance.
First of all, give full play to the pumping force of exhaust equipment, can be from two aspects. , one is to prevent cold air intrusion stove kiln preheating zone and total flue is in negative pressure zone, the cold is very easy to never tight place into furnace, mixed with flue gas after the exhaust equipment from outside the furnace. After cold air invading stove, not only reduce the flue gas temperature, and the volume of the kiln cooling zone decreases, it will certainly reduce the calcining zone in the combustion air supply, slows down the body burnt and fuel combustion speed. Second, reasonable use of air brake, avoiding the appropriate increase with more, the ventilation area of gate will increase, the flow resistance is small, exhaust equipment of the suction force can be fully displayed.
In addition, by avoiding the adjusting, can control the flow of gas stove, adjust the flow rate of each part, make full use of waste heat preheating body, can greatly shorten the preheating process, speed up burning process.
Finally, reduce system resistance for increasing furnace ventilation rate is also very important. In furnace gas movement of all kinds of resistance, is setting and decisive when setting resistance. Setting the size of the resistance, mainly depends on the degree of light setting and gas through setting pathways. Setting the rarer, the shorter the path, then the smaller resistance; Setting the secret or path, the longer, the greater the resistance. Second, setting the quality of operation, has a certain influence on setting resistance. When setting requirements headon, seam to seam, fire way to straight, fire road unimpeded. So, can reduce resistance, on the other hand, the resistance will increase.
