The objective of the invention is to overcome above-mentioned deficiency, a kind of method that can realize that fuel is controlled automatically for the industrial furnace burner multi-parameter of the accurate control needs of combustion-supporting air quantity in the combustion process is provided.
A kind of industrial furnace burner multi-parameter method of control automatically that is achieved in that of the present invention is in the fuel feed pipeline upper edge of industrial furnace burner fuel feed direction fuel flow rate to be installed successively to show control instrument, fuel pressure indicator, fuel flow control valve and blowout protection magnetic valve; Flame detector is installed on industrial furnace burner, and this flame detector is connected with described blowout protection solenoid control signal; Boiler tube or furnace outlet display temperature controller table are installed on the outlet line of industrial furnace, and this boiler tube or furnace outlet display temperature controller table show that with described fuel flow rate control instrument is connected with the fuel flow control valve control signal respectively; Combustion-supporting gas amount control and regulation valve and combustion-supporting gas flowmeter are installed on the air intake pipeline of industrial furnace burner; Exhanst gas outlet at industrial furnace is equipped with the flue gas detector, and the output control signal of this flue gas detector is connected with the fuel flow control valve control signal with described combustion-supporting gas amount control and regulation valve, combustion-supporting gas flowmeter respectively; The temperature parameter that adopts boiler tube or furnace outlet display temperature controller table to record is a control signal, the fuel flow rate of control fuel feed shows the fuel flow control valve of control instrument and fuel feed, judge by the fuel pressure indicator of fuel feed whether fuel pressure satisfies the burning demand, fuel flow rate on the fuel feed pipeline of industrial furnace burner shows that the parameter of control instrument is a control signal, feed back to fuel flow control valve fuel metering amount to satisfy the fuel quantity that outlet temperature requires, fuel flow rate on the fuel feed pipeline of industrial furnace burner shows that the parameter of control instrument is a control signal, control combustion-supporting gas flowmeter, combustion-supporting gas flowmeter feedback signal control ratio is regulated combustion-supporting gas amount control and regulation valve, and the online oxygen content parameter that records of flue gas detector of kiln gas outlet is regulated the higher limit control parameter of combustion-supporting air quantity or amount of oxygen as combustion-supporting gas amount control Flux Valve Control parameter; Online carbon monoxide that records of flue gas detector or propellant composition content parameter with the kiln gas outlet are controlled the Flux Valve Control parameter as the combustion-supporting gas amount; for regulating the lower limit control parameter of combustion-supporting air quantity or amount of oxygen; realization is to the burner multi parameters control; simultaneously; when fray-out of flame, pass through blowout protection magnetic valve, the supply of fuel shutoff.Reach the purpose of safety interlocking.
Principle of the present invention is: the combustion-supporting air quantity that combustion process needs is fixed, and for the combustion-supporting gas that fully carries out that guarantees combustion process needs certain excess quantity, the height of coefficient of excess has reflected the advanced degree of burner.Gaseous fuel excess air coefficient in the design of general industry stove is 1.05～1.15, and the liquid fuel excess air coefficient is 1.1～1.20.When fuel quantity reduces, require its combustion-supporting air quantity or the amount of oxygen should corresponding minimizing, otherwise the combustion-supporting air quantity that enters too conference cause the increase of exhaust gas volumn, exhaust gas volumn increases the heat that just causes flue gas to take away and increases; When fuel quantity increases, require its combustion-supporting air quantity or the amount of oxygen should corresponding increase, otherwise the too little meeting of combustion-supporting air quantity that enters cause fuel combustion insufficient, not only wasted energy but also contaminated environment.Along with the high-temp combustion The Application of Technology, the control of excess air coefficient is that the gaseous fuel excess air coefficient is 1.03～1.10, and liquid and solid fuel excess air coefficient are 1.05～1.15.Coefficient of excess is lower when pure oxygen is combustion gas.Superfluous combustion air or the low more burner control of excess oxygen coefficient are advanced more.
The invention has the beneficial effects as follows:
1) heating stove exhanst gas outlet oxygen content, carbon monoxide or propellant composition content, boiler tube material or multi-parameters such as furnace outlet temperature, fuel quantity the accurate control that has been coupled to combustion-supporting gas.
2) by be parameter to stove outlet smoke components on-line analysis result, adjusting burner air valve opening has avoided huge or can not problem of implementation to the structure that in the air metering process straight length requirement is caused.
3) when accurately accurately the control of combustion-supporting gas amount can reach combustion efficiency the best, the minimum of superfluous combustion-supporting gas amount, thus reach energy-saving and emission-reduction.
