摘要： A burner system for a furnace. The system may have a wedged or other shaped burner box. An air-fuel mixer may be attached to a smaller end of the burner box at about a right angle relative to a direction of a gas and air mixture leaving the larger box end. A burner head may be attached to the larger end of the box. The burner head may be sufficient for numerous heater sections of a heat exchanger. A spacer and an orifice shield may be situated between the burner head and heat exchanger. A fan may pull in the gas and air mixture from the mixer, through the box and the burner head. The mixture may be ignited into a flame which is pulled into the heat exchanger. Some of the flue gas from the exchanger exhaust may be recirculated by being added with air to the mixer.

摘要： A furnace is disclosed that includes a burner with a firing rate that is variable between a minimum and a maximum firing rate. After a call for heat is received, the firing rate is set to an initial level above the minimum firing rate, and the burner is ignited. The firing rate is then modulated downward toward the minimum firing rate. If the flame is lost during or after modulation, the burner is reignited and the firing rate is maintained above the firing rate at which the flame was lost until the current call for heat is satisfied. In some cases, the firing rate is maintained until one or more subsequent calls for heat are satisfied.
