How to control the outlet temperature of aquaculture hot blast stove

The air temperature value of the hot air stove for breeding can meet people's needs. It should not be too high or too low. But how to control the outlet temperature of the breeding hot air furnace? what can I do?

According to the demand and temperature of hot air, the given fuel supply is balanced according to the heating value, and the air-fuel ratio is automatically achieved. Then, according to the requirements of the outlet temperature of the hot blast stove, adjust the supply of adjustable temperature air. At this time, in order to achieve the purpose of controlling the outlet temperature of the hot blast stove, the temperature lag problem should be considered.

When adjusting the outlet temperature of the breeding hot air furnace, the fuel supply will increase as the temperature of the hot air or the flow rate of the breeding hot air furnace increases. The fuel supply can be controlled by the fuel regulator only when the frequency converter of the combustion fan controls the increase in air supply and feeds it back to the fuel regulator. Instead, only when the fuel regulator controls the increase in fuel supply. When the fuel quantity is reduced and fed back to the combustion air regulator, the combustion air converter can control the reduction of the combustion air supply.
