Integrated dual chamber burner with remote communicating flame strip

摘要

A dual chamber burner assembly provides a header, a first burner chamber adjacent the header, and a second burner chamber on an opposite side of the first burner chamber from the header. The second burner chamber is provided with a flame sensor portion extending back through the first burner chamber toward the header so that first and second flame sensors may be utilized to detect flame in the first and second chambers, respectively.

主权项

1. A burner assembly, comprising:
a header including a first fuel and air inlet and a second fuel and air inlet; a first burner chamber adjacent the header, the first burner chamber including a first foraminous outer burner surface, the first fuel and air inlet being communicated with the first burner chamber; and a second burner chamber on an opposite side of the first burner chamber from the header, the second burner chamber including a second foraminous outer burner surface located on an opposite side of the first foraminous outer burner surface from the header, the second fuel and air inlet being communicated with the second burner chamber, the second burner chamber having a flame sensor portion extending into the first burner chamber back toward the header, the flame sensor portion including a flame indicating foraminous outer burner surface of the second burner chamber extending from the second foraminous outer burner surface back toward the header, so that a flame sensor located adjacent the flame sensor portion of the second burner chamber need not be exposed to flame from the first burner chamber.
