The variations of pressure amplitude, static thrust, heat flux, operating frequency, wall and gas temperatures with fuel flow rates are valveless pulsed combustors. Wall and gas temperatures, static thrust, pressure amplitude, and heat flux in the combustors increased with fuel flow rate. The valves of gas temperature and thrust produced show that this combustor is suitable for melting and heat treatment furnaces. Despite the high convective heat transfer in the pulse combustor, only about 10 % of the heat generated is lost through the wall, the rest being available in the exhaust jets for heating in the furnace.
