Semi-automatic features
1. Ignition method: automatic/manual combination
2. Control mode: automatic/manual; using combustion program controller control, flame tracking monitoring, flameout alarm, fast fuel gas cut off, gas low pressure protection, manual switch air volume valve, manual heat load adjustment and other functions;
3. Combustion method: It has the characteristics of single gas, single fuel oil, and oil and gas mixed combustion, and in the normal combustion process, there is no tempering, no misfire, and no flameout. It has the characteristics of sufficient combustion and stable thermal efficiency, simple operation and convenient maintenance.
4. Combustion control program: start → start the fan → manually open the air volume control valve to purge the chamber → start the combustion program controller → manually close the air volume control valve → open the high-energy igniter → open the ignition solenoid valve → flame tracking monitoring (open the main gas Valve→manually open the air volume control valve)→manually adjust the fuel valve and air volume valve→to the normal combustion rated working state→flame extinguishment (flame-out alarm in the fault state, automatic fuel gas cut off)→stop.
Working principle and characteristics of automatic burner
1. Working principle
The gas sent from the gas pipeline is sprayed into the combustion chamber through the solenoid valve or electric control valve, the gas distributor and the nozzle, and is cut by the strong collision of the shaft, the radial direction and the cyclone in the combustion chamber to form a mixed gas, which is ignited by high-energy electronic , Immediately produce combustion, form a stable stream flame, and send it to the furnace. When the flame advances to the furnace, the gas is mixed with the combustion-supporting air again to form a semi-internal mixing and semi-diffusive combustion. In terms of the air-fuel ratio, the combustion-supporting air is proportionally adjusted with the flow of gas to achieve full mixing and complete combustion. In order to ensure the safe operation of the burner under the rated thermal load, a photosensitive element is used to track and monitor the flame. Once a failure occurs to extinguish the fire, the program controller will immediately issue an instruction to close the gas valve and give an alarm in time. The fan automatically purges the residual gas in the furnace. After the internal combustible gas is exhausted, the re-ignition procedure is implemented again. In terms of thermal load adjustment, the temperature/pressure control area (or set working point) is automatically and randomly adjusted according to the requirements of the production process.
2. Main features
1) According to the installation position and the size of the load, the structure of the burner is: one-piece and split-type.
2) Regardless of the thermal load of the burner, an ignition gun is set in the combustion chamber to implement light-load ignition and work under heavy load, thereby effectively preventing the occurrence of furnace explosion accidents.
3) The heat load adjustment ratio is large (30-110%), and the heat load can be changed at any time according to the requirements of the production process. The ratio adjustment is realized in the wind-fuel ratio to achieve complete combustion, which effectively saves energy, prevents combustible gas from being discharged into the atmosphere, and protects surroundings.
4) High combustion efficiency (≥98%).
