Abstract
The utility model discloses a kind of kiln air-fuel ratio regulation system, include the burner being located in kiln and thermocouple, temperature control instrument, gas control valve, air control valve and air-fuel ratio controller, thermocouple is connected with temperature control instrument, gas control valve is mounted on the gas pipeline of burner, air control valve is mounted on the air pipeline of burner, it is characterised in that：The temperature control instrument is connected with air-fuel ratio controller, and air-fuel ratio controller is connected with gas control valve, air control valve respectively.According to the firing process of different adobes, realize that the kiln burner in different firing stages has different optimal air-fuel ratios, simultaneously when empty kiln, when burner is in low fiery state, combustion air can also realize the optimal proportion of adjust automatically and combustion gas, whole process kiln burner is automatically controlled by air-fuel ratio controller completely, realizes the best energy-saving effect of kiln.
Description
Technical field
The utility model is related to kiln technical fields, are especially used to control the adjusting management system of kiln burning.
Background technology
The combustion control mode of current Industrial Stoves is typically all that temperature control instrument detects kiln in-furnace temperature by thermocouple,
When detecting temperature signal and set temperature difference, automatic adjustment gas control valve aperture adjusts burner power, this process
Middle combustion air can only be adjusted manually, can not accurately control air-fuel ratio.Especially current ceramic roller path kiln, all existing can not
The problem of accurately controlling the air-fuel ratio of burning causes efficiency of combustion low, wastes fuel, and kiln temperature is difficult to ensure.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of tune for the air-fuel ratio accurately controlling kiln burning
Save management system.
Used technical solution to solve above-mentioned technical problem：A kind of kiln air-fuel ratio regulation system, includes to be located at
Burner and thermocouple, temperature control instrument, gas control valve, air control valve in kiln and air-fuel ratio controller, thermocouple
It is connected with temperature control instrument, gas control valve is mounted on the gas pipeline of burner, and air control valve is mounted on the air hose of burner
On road, it is characterised in that：The temperature control instrument is connected with air-fuel ratio controller, and air-fuel ratio controller is adjusted with combustion gas respectively
Valve, air control valve are connected.
Using advantageous effect caused by the utility model：According to the firing process of different adobes, different firing ranks are realized
The kiln burner of section has different optimal air-fuel ratios, while when empty kiln, and when burner is in low fiery state, combustion air also can be real
The optimal proportion of existing adjust automatically and combustion gas, whole process kiln burner are automatically controlled by air-fuel ratio controller completely, real
The best energy-saving effect of existing kiln.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model kiln air-fuel ratio regulation system.
Specific implementation mode
As shown in Figure 1, a kind of kiln air-fuel ratio regulation system, includes the burner 2 being located in kiln 1 and thermocouple 3, temperature
Control instrument 4, gas control valve 5, air control valve 6 and air-fuel ratio controller 7, thermocouple 3 are connected with temperature control instrument 4, fire
Gas regulating valve 5 is mounted on the gas pipeline 8 of burner 2, and air control valve 6 is mounted on the air pipeline 9 of burner 2.In this reality
In novel, the temperature control instrument 4 is connected with air-fuel ratio controller 7, air-fuel ratio controller 7 respectively with gas control valve 5,
Air control valve 6 is connected.
Usually, ceramic roller path kiln is equipped with multiple control groups with the regulating system, and each control group includes multiple
Burner 2.When thermocouple 3 detects that temperature in kiln 1 and the setting value of temperature control instrument 4 have differences, temperature control instrument 4 is by signal
Electronics air-fuel ratio controller 7 is fed back to, electronics air-fuel ratio controller 7 will simulate the best air-fuel at a temperature of this at this time
Than, send out control signal, automatically control gas control valve 5 and 6 aperture of air control valve make every group of burner 2 by after simulation most
Good air-fuel ratio is burnt, and reaches best energy-saving effect.
