The method of combusting lean fuel-air mixtures comprising the steps of: a. obtaining an admixture of fuel and air, said admixture having an adiabatic flame above about 900°Kelvin; b. passing least a portion of said admixture into contact with one or more mesolith combustion catalysts operating at a temperature below the adiabatic flame temperature of said admixture thereby producing reaction products of incomplete combustion; and c. passing said reaction products to a thermal reaction chamber; thereby igniting and stabilizing combustion in said thermal reaction chamber.

A high turndown ratio thermal gas phase combustion system for operation at temperatures well below the stable operating temperature of conventional gas turbine combustors comprising: a. a thermal reaction chamber, having a fluid inlet and an outlet; b. continuous catalyst means for stabilizing lean combustion in said chamber, mounted in the fluid inlet; c. means for passing a lean admixture of fuel and air into contact with said catalyst means to produce a reacted admixture having a temperature below the safe operating temperature of said catalyst means, and d. means for passing said reacted admixture to said thermal reaction chamber for stable combustion; said catalyst means being a channeled catalyst body, said channels having a flow path of no more than about 6 mm and a ratio of channel path length to diameter of less than about 2 to 1 whereby the flow path through which the portion of fluid admixture passes through the channel is no more than one-half the length for full boundary layer build-up in the channel.
