1. Oil burners:
A) Test all the oil pipes and systems of the burner at 1.25 times the maximum fuel design pressure, and visually check whether there is oil leakage or seepage.
B) After the burner stops working, check whether the nozzle has oil dripping.
2. Gas burners:
From the gas delivery components of the burner to the last safety shut-off valve, the air tightness test is carried out with 1.25 times the maximum gas design pressure of the gas, and each interface is checked with a gas leak detector or soapy water. There must be no leakage. The specific contents of the air tightness test of the gas pipeline system include:
a) The gas valve is in the closed state, and the compressed air with a pressure of 1.25 times the maximum gas design pressure is used. The pressure is stabilized for 1 minute to see if the system pressure drops;
b) The burner is in working state, and the pressure of the inlet is adjusted to reach the specified value. The air tightness test is carried out using a gas leak detector or a foaming medium. If no bubbles are found, the air tightness of the system can be considered good.
c) Test the two control valves separately, artificially close one of the valves and keep the other valves open, use compressed air with a pressure of 1.25 times the maximum gas design pressure, stabilize the pressure for 1 minute, and see if the system pressure drops.
