ODS pilot burner
Working principle
ODS use thermocouple component as a sensor to search the temperature of pilot flame in order to drive the electromagnetic valve, when the space is hypoxia(O-17%~19%),the flame temperature is under 400°C,there is not enough potential to open the valve ,so then the valve will be closed to keep safe.Main function
To ignite the main burner without deflagration, to stabilize the flame of main burner, to detect flame normality , and to reignite or cut off the energy source when the flame is put out by external factors.
The pilot flame of the ODS system is in contact with the ODS thermocouple that generates the necessary millivoltage needed to hold the solenoid safety gas valve inside of the control valve in the open position.The ODS safetu valve is a "Spring-Loaded Normally Closed" gas valve.
