Why is the low interlock pressure of the constant-light burner slightly higher than that of the main burner?
Thread Content
The interlock conditions for the furnace in our device are as follows: 1) The low-low interlock pressure for the pilot light is 0.01 MPa, and 2) the low-low interlock pressure for the main burner is 0.005 MPa. Why is the set pressure for the pilot light higher than that for the main burner?
An ever-burning lamp is prone to going out. The flame is small
A small flame of a perpetual light is easy to go out.
Is the location of the pressure measurement point the same? If the positions are the same, as far as I know, the pressure of the constant-flame burner should be slightly lower than that of the main burner
Prevent the eternal flame from going out, and prevent backflow at the burner.
To prevent extinguishment due to fluctuations in fuel gas pressure.
