The operation of kiln firing involves multiple aspects and is comprehensive. Only by carefully and reasonably handling all aspects can the goal of reducing firing energy consumption be achieved.
Firstly, it is necessary to strictly control the residual moisture content of the dry greenware entering the kiln, reduce the heat energy consumed for removing water from it, increase the temperature rise rate, and reduce the energy consumption during the preheating stage.
Secondly, it is necessary to control the length and stability of each zone during firing. The length of each zone should not be unstable, varying from long to short, or the zones should not be unable to be fixed in their required positions, resulting in a "drifting" phenomenon along the length of the kiln. This can also consume a significant amount of energy during firing.
Thirdly, utilize the air brake on the kiln reasonably and maximize the use of waste heat from the kiln. The higher the utilization rate of waste heat, the lower the energy consumption for kiln firing.
Fourthly, strengthen the inspection of the sealing performance of the kiln body to prevent hot gases inside the kiln from escaping and cold air outside from entering. Both the leakage of hot gases and the infiltration of cold air result in the loss of thermal energy in the kiln, which increases the energy consumption for kiln firing instead of reducing it.
Fifthly, we should accelerate the recycling frequency of kilns, reduce the heat storage loss of kiln bodies and kiln cars, and fully utilize the accumulated thermal energy, thereby reducing energy consumption during the firing process.

Sixth, improving the sintering yield is the most direct and effective way to reduce the energy consumption of kiln sintering. By increasing the sintering yield, not only can a significant amount of heat energy be saved, but also considerable amounts of electric energy, labor costs, and raw material expenses can be reduced.
At the same time, it is necessary to accurately grasp the heat conditions inside the kiln, recognize the trend of temperature changes inside the kiln, and judge whether the indoor temperature is rising or falling, providing a reliable basis for adding external combustion. It is important to follow the principle of "adding coal based on the fire, adding frequently but in small amounts, and adding in small amounts but multiple times". Add fuel according to the burning speed of the fuel inside the kiln. Neither too little fuel, which fails to meet the temperature rise requirements, nor too much fuel, which leads to incomplete combustion, should be used. Accurately grasp the calorific value of the fuel added to the kiln and add fuel according to the required heat inside the kiln. If the calorific value of this batch of fuel is higher than that of the previously used fuel, less should be added. If the calorific value of this batch of fuel is lower than that of the previously used fuel, more should be added.
