ABSTRACT:
A fuel fired burner comprises a chamber for receiving a premixture of fuel and air. A wall of the chamber is in the form of a flamestrip provided with a plurality of elongate slots extending through the wall. Each slot has an inlet portion which converges to an end leading to a substantially constant dimension portion. The pitch of the slots along the chamber wall is P, the width of each slot is w, and the length of the constant dimension portion is L. The dimensions of the flamestrip are arranged such that L/w.gtoreq.10 and P/w.gtoreq.2. A burner including such an arrangement reduces the likelihood of resonant combustion noise being generated when enclosed within a heating appliance.
