Claims

[Scope of utility model registration request]

(1) The volume of gas or air, etc. in the piping upstream from the pressure reducing device such as the orifice is equal to 3 of the internal volume of the pipe in the pressure section between the pressure reducing device such as the orifice and the burner that is ultimately supplied to the burner.
A pressure reducing device such as an orifice is placed in a position where the volume is more than double, and the gas or air pressure (supply pressure) on the upstream side (in the piping part with three times the volume or more) is adjusted during expected fluctuations in the furnace pressure. A combustion equipment piping system characterized in that the piping system is 10 times or more.

(2) The combustion equipment piping system according to claim (1), in which a pressure reducing device such as an orifice is located closer to the burner than the manual stop valve.
