초록 ▼

A burner control system for controlling gas flow to a burner in response to a pressure differential indicative of air flow to the burner, the pressure differential being impressed across a diaphragm which actuates a bleed valve controlling the pressure on one side of the diaphragm actuator of a fuel valve. The bleed chamber is connected to the outlet of the gas valve and the low pressure side of a pressure differential through separate flow restrictors.

대표청구항 ▼

A fuel control system for burner apparatus including a gas nozzle and an air passageway for supplying fuel gas and air to a burner in a combustion chamber, the air flow to the burner being variable in response to heat output required from the burner apparatus, the control system comprising: a flow sensor operable to produce a differential pressure signal between high and low pressure ports thereof indicative of the rate of air flow to the burner; a gas valve having an inlet for receiving fuel gas from a gas supply and an outlet, the inlet and outlet being connected through a valve seat, said gas valve further having a closure member moveable toward and away from the valve seat by means of a gas valve diaphragm which separates first and second control chambers of which the first control chamber communicates with the outlet so as to be maintained at the outlet gas pressure; a first passageway for connecting the outlet of said gas valve to the gas nozzle of the burner apparatus; a second passageway containing a flow restrictor connecting the inlet of said gas valve to the second control chamber thereof; a control module including a control module diaphragm separating bleed and control chambers communicating with first and second ports respectively, the bleed chamber further communicating with a valve seat through which flow is variably restricted by a moveable closure member carried on the control module diaphragm; third and fourth passageways respectively connecting the low and high pressure ports of said flow sensor to the first and second ports of said control module, said third passageway containing a flow restrictor; a fifth passageway providing fluid communication between the valve seat of said control module and the second control chamber of said gas valve; and a sixth passageway containing a flow restrictor connecting the outlet of said gas valve to the first port of said control module.
