An apparatus is provided which is adapted to be located in a conduit to be severed. The apparatus includes an upper ignition device, combustible material and a lower nozzle with a diverter. In operation the ignition device is actuated to ignite the combustible material to form a flame of hot gases for passage through apertures of the nozzle to the diverter which directs the hot gases radially outward and against the conduit to be severed. A uniform mixing cavity is provided above the nozzle in the flow path of the flame to the nozzle for mixing the hot gases prior to passages through the nozzle. A lower cavity is provided for the hot gases flowing out of the nozzle for pressurizing the hot gases at the outlet of the apparatus.
