Abstract
The present invention discloses a kind of coefficient of excess air management system of kiln, include the burner being located in kiln and thermocouple, temperature control instrument, combustion gas actuator, gas ratio valve, air actuators and industrial computer, the combustion gas actuator and gas ratio valve are successively connected on the gas pipeline of burner, air actuators are connected on the air duct of burner, the air pressure detection of gas ratio valve is connected with the air duct of burner, and thermocouple, industrial computer, combustion gas actuator and air actuators are connected with temperature control instrument.The present invention realizes that the different burner groups for burning till the stage have different optimal air-fuel ratios, while when empty kiln, when burner is in low fiery state, combustion air can also realize the optimal ratio of adjust automatically and combustion gas according to the firing process of adobe.Whole process by the programme-control finished in advance, can realize the accurate control of coefficient of excess air completely, ensure that fire box temperature is stable, and efficiency is burnt till in raising, reduces energy consumption.
Description
Technical field
The present invention relates to kiln technical field, is especially used for the management system for controlling kiln to burn.
Background technology
The coefficient of excess air of kiln, during burning within the scope of general control certain numerical value.Coefficient of excess air is too small, combustion
Burn incomplete, waste fuel, coefficient of excess air is too big, enters that stove air is too many, and fire box temperature declines, and conduct heat bad, flue gas band
It is more to walk heat, wastes the energy.
However, existing kiln is difficult to accomplish that coefficient of excess air accurately controls, cause fire box temperature unstable, burn till effect
Fruit is not good enough, and energy consumption is big.Therefore, it is necessary to research and develop a kind of management system that can be used for accurate control kiln coefficient of excess air.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of management system for being used to accurately control kiln coefficient of excess air
System.
Technical scheme used by solve above-mentioned technical problem：A kind of coefficient of excess air management system of kiln, bag
Include the burner being located in kiln and thermocouple, temperature control instrument, combustion gas actuator, gas ratio valve, air actuators, Yi Jigong
Control computer, it is characterised in that：The combustion gas actuator and gas ratio valve are successively connected on the gas pipeline of burner, air
Actuator is connected on the air duct of burner, and the air pressure detection of gas ratio valve is connected with the air duct of burner, heat
Galvanic couple, industrial computer, combustion gas actuator and air actuators are connected with temperature control instrument.
Using beneficial effect caused by the present invention：Coefficient of excess air management system is by combustion gas actuator, air
The cooperating of actuator, gas ratio valve, temperature control instrument and industrial computer etc., according to the firing process of adobe, realize
The burner group that difference burns till the stage has different optimal air-fuel ratios, at the same when empty kiln, when burner is in low fiery state, combustion air
Also the optimal ratio of adjust automatically and combustion gas can be realized.Whole process can realize air excess by the programme-control finished in advance completely
The accurate control of coefficient, ensure that fire box temperature is stable, efficiency is burnt till in raising, reduces energy consumption.
Brief description of the drawings
Fig. 1 is the structural representation of coefficient of excess air management system of the present invention.
Embodiment
As shown in figure 1, a kind of coefficient of excess air management system of kiln, includes the burner 2 being located in kiln 1 and heat
Galvanic couple 3, temperature control instrument 4, combustion gas actuator 5, gas ratio valve 6, air actuators 7 and industrial computer 8, in the present invention
In, combustion gas actuator 5 and gas ratio valve 6 priority is connected on the gas pipeline 9 of burner 2, and air actuators 7 are connected on
On the air duct 10 of burner 2, the air pressure detection of gas ratio valve 6 is connected with the air duct 10 of burner 2, thermocouple 3,
Industrial computer 8, combustion gas actuator 5 and air actuators 7 are connected with temperature control instrument 4.
Coefficient of excess air management system operation principle (by taking single control group as an example)：Thermocouple 3 is detected in burner hearth
When temperature and the setting value of temperature control instrument 4 have differences, temperature control instrument 4 controls combustion gas actuator 5 to carry out regulating gas quantity delivered, this
When combustion gas actuator 5 before combustion gas gross pressure be proportional with combustion air in the presence of gas ratio valve 6.Work as work
When control computer 8 detects that the temperature that fire box temperature is set with temperature control instrument 4 is not reaching to consistent within the time that system is set,
Temperature control instrument 4 is issued instructions to drive air actuators 7 to open big or open small combustion air volume, and the combustion gas before combustion gas actuator 5
Gross pressure is all the time proportional with combustion-supporting wind pressure in the presence of gas ratio valve 6.Burnt till according to kiln is different
Region can manually adjust proportioning valve to change the ratio of combustion gas gross pressure and combustion-supporting wind pressure, to ensure realizing perfection
Calcining system on the premise of, reach optimal energy-saving effect.
