Abstract
A combustion chamber has an inner wall defining an inner chamber. The inner wall is perforated to admit combustion air into the inner chamber. The combustion chamber has an outer wall defining an outer chamber. The outer wall is perforated to admit combustion air from a pressurized air plenum to the inner wall. The inner and outer wall are spaced apart such that air may flow between the inner and outer walls.
