1. A tool for generating steam and combustion gases for producing oil from an oil well, the tool comprising:
a main body with a first end configured to receive inputs, the inputs including air, fuel and water;
an ignition component within the tool configured to ignite fuel and air to generate a flame;
a combustion chamber for accommodating the flame, the combustion chamber extending at a second end of the main body opposite the first end and defined by a wall and an outlet configured to allow the exit of combustion products; and
a water passageway that extends through the main body from the first end and terminates at a nozzle on an outer surface of the tool, the nozzle configured to direct a flow of water at least in part axially along an exterior length of the wall outside of the combustion chamber, wherein water is at least partially vaporized along the exterior length of the wall to generate steam.
