Integrated gas burner assembly

摘要

A gas burner assembly (10) and method for providing combustion air flow and gas fuel flow in linear proportion to a control signal. A blower motor (18) is driven by the control signal and drives a blower (14) whose output (16) has a static pressure proportional to the square of the blower speed. A gas fuel controller 28 is responsive to the static pressure of the blower output (16) to meter fuel in proportion to the square root of that static pressure.
