heat treatment furnace of burner and control system

Brief introduction of burner and control system of heat treatment furnace

1. Take all kinds of combustible gases as the medium, and heat them through various burners, so that the temperature in the heat treatment furnace reaches 1200℃.

2. High speed burner is used for heating in the heat treatment furnace, with a high spewing speed up to 100m/s. The burner is evenly distributed on both sides, which can effectively stir the atmosphere in the furnace and make the temperature in the furnace even. Gas burner can ratio continuously adjust combustion, actuators to adjust the size of air volume, through the size of the proportional valve to adjust the volume of gas, achieve air-fuel ratio, combustion gas and air has a lower limit, each burner gas pipe is equipped with the control solenoid valve, each burner with complete combustion controller independently, with automatic ignition, flame detection, automatic fire alarm to snuff out. This fully ensures the stability of the combustion temperature control system.

3. The burner system burns completely to make full use of the fuel. Adopt the zero control of furnace pressure and full sealing technology, it is the combination surface of the trolley and the furnace (the sealing surface between the trolley and the furnace body) is in the zero furnace pressure, the furnace gas does not leak out, the cool air does not leak in, so that the heat energy generated by combustion can be effectively used.

4. The preheater adopts GC type tube type insert spoiler heat exchanger to increase the preheating temperature of the air. When the furnace temperature is 1000℃, the air temperature is preheated to 300-350℃.

5. Heat exchanger is designed with heat resistant steel and stainless steel according to different temperatures, and uniformity and thermal stress relief measures are adopted in layout.

6. Control system. The control system of the whole fiber heat treatment furnace mainly regulates and controls the flow rate of the gas pipe and the flow rate of the flue gas and the diluted air of each furnace through the temperature and pressure detection in the furnace, and is equipped with the quick cutting device of the natural gas main.

7. If the air pressure, gas pressure and compressed air pressure do not meet the requirements, the burner combustion will not start, if the burning is closed.

8. The top of the heat treatment furnace is equipped with automatic furnace pressure control and butterfly valve, etc., which can adjust the cooling rate.
