Abstract

See full text

Method of combusting hydrocarbon fuel to form combustion products low in nitrogen dioxide (NO2) and carbon monoxide (CO) and mixing the combustion products with additional air to provide a heated air stream suitable for heating enclosed spaces includes the following steps: (a) delivering a fuel stream to a burner assembly; (b) delivering a combustion air stream to the burner assembly; (c) combining the fuel and air streams within a combustion chamber and heat exchanger wherein the mixture is ignited, completely combusted, and the temperature of the products of combustion are reduced; (d) providing tempering air to the external side of the combustion chamber and heat exchanger to transfer heat away from the combustion gases to tempering air; (e) combining the partially heated tempering air and cooled combustion products low in NO2 and CO; and (f) discharging the mixture into a space to be heated.
