Abstract
An integrated burner system is disclosed having a fuel supply assembly including a fuel control for variably limiting the flow of fuel into the burner along with a discrete air control for generating a variable flow of air into the burner. The respective fuel and air controls are directed by a control system which operates these controls in order to provide and maintain a desired fuel-to-air ratio between high fire and low fire in response to a requirement for heat. A multiple burner embodiment is disclosed in which a plurality of the present integrated burners may be used to create a multiple burner system which provides a greater degree of control and efficiency than that capable with previous systems. The multiple burner embodiment also eliminates the costly installation and maintenance requirements typically associated with previous systems.
