ABSTRACT:
A gas-fired combustion apparatus includes a porous combustion surface disposed in a combustion chamber substantially sealed to prevent entry of secondary air and having a pressure relief means that operates to relieve or suppress pressure changes which may otherwise occur in the combustion chamber with commencement of the burner operation. Thereafter a subatmospheric pressure is maintained in the combustion chamber by a natural or aspirated draft. The subatmospheric pressure cooperates with an aspirating flow of fuel to the burner apparatus to provide an increased flow of primary combustion air which reduces the combustion temperature and the emission of pollutants. Alternatively, the subatmospheric pressure may be used to achieve a given flow of primary combustion air with a reduced combustion surface area. Water heater applications of the burner apparatus are illustrated.
