The combustion-supporting air is prepared according to the requirement of natural gas according to a certain proportion, and provides power for the natural gas, so that the natural gas is atomized more fully, and the firing effect is improved. During proportioning, when the amount of natural gas is reduced, the amount of combustion-supporting air also needs to be correspondingly reduced, if the reduction amount of the combustion-supporting air is too small, redundant combustion-supporting air needs to be additionally heated to thousands of degrees, and the energy consumption is increased; if the combustion-supporting air is reduced too much, the kinetic energy of the natural gas is insufficient, the atomization is uneven, the combustion is insufficient, and the waste of the natural gas is caused. At present, a common proportioning mode is that a proportional valve is installed on a combustion-supporting air inlet pipe, and an actuator is used for controlling the opening degree of the proportional valve, so that the quantity of the combustion-supporting air is adjusted, but the control mode can cause the kinetic energy of the combustion-supporting air passing through the proportional valve to be reduced, the combustion-supporting air does not have enough kinetic energy at a nozzle to blow natural gas away and mix, the natural gas is not combusted fully, waste is caused, the flame temperature is reduced, and the firing effect is influenced.
