A variable firing rate burner with a throttle valve assembly that regulates fuel and air intake while maintaining a substantially constant fuel/air ratio over a wide fuel/air flow rate range. The throttle valve assembly includes a pivotally mounted throttle plate that seats on an input manifold, the throttle plate being moved by a driver between low and high firing rate positions. Fuel and air are drawn through the throttle valve assembly and into a mixing chamber by a blower and directed to a flameholder where ignition occurs.
A variable firing rate burner comprising: (a) inlet means through which fuel and air flow, said inlet means including gas inlet means and air inlet means, said gas inlet means disposed within said air inlet means; (b) valve means for controlling fuel/air ratio and the flow rate of said fuel and air flowing in said inlet means, said valve means movable between a first position and a second position, said fuel/air flow rate being greater at said second position than at said first position, said fuel/air ratio being maintained as said valve means is moved f...
