求翻译：在保证煤气完全燃烧的条件下，控制空气过剩系数于最小值，可以获得最高的理论按烧温度，并且可以减少烟气生成量，进而减少烟气带走的热量。是什么意思？

Conditions to ensure complete combustion of gas, controlling the excess air ratio at the minimum, and maximum theoretical temperature according to burn, and can reduce the amount of flue gas generated, thereby reducing the heat taken away by the flue gas.

Burns completely in the guarantee coal gas under the condition, the control air surplus coefficient in the minimum value, may obtain the highest theory according to burn the temperature, and may reduce the haze production quantity, then the reduced haze carries off quantity of heat.

In ensuring complete combustion of the gas under the conditions, control of air excess coefficient to the minimum value, theory of maximum burning temperature can be obtained, and can reduce the amount of smoke generated, thereby reducing the heat of the flue gas to take away.
