This paper presents a new solution to the problem of heat protection for flame tubes used in industrial combustion chambers, burners, furnaces, gas turbines, etc. A comparison is made between the methods used for cooling existing flame tubes, and a new flame tube design, which simplifies construction, improves cooling and overcomes several other problems in existing designs. Principles of this new design are explained using flow and temperature measurements along with mathematical modeling. Industrial applications of this design are given. One application is a heat generator without refractory lining or high temperature alloys that replaces refractory lined combustion chambers. Other applications include combustion chambers for industrial heating, steam boilers and gas turbines operating on gaseous and liquid fuels. Special applications illustrated are recycling of combustion products for low NOx, high temperature treatment of particles, and nearly adiabatic combustion at less than 2% excess air.
