Pulsing combustion

A pulsing combustion device of claim further comprising:

• a water chamber encircling said pulsing combustion device with water flowing past said device to cool said device and to heat said water;
• a water line for supplying water into said water chamber;
• means for venting said water and said combustion gases with the water turned into steam by contact with the combustion gases;
• an outlet orifice through which said steam and said combustion gases are exhausted;
• means for supplying a detergent to said means for venting, said detergent mixing with said steam and said combustion gases forming a steam cleaning device.

A water heater comprising a tank for containment of water and a pulsing combustion device in heat transfer relation thereto, said pulsing combustion device comprising:

• means for defining an elongate combustion chamber having an inlet for a combustible mixture and an unvalved outlet for combustion gases;
• a floating valve member mounted in reciprocation relation in a wall of said combustion chamber, said valve member having a first side in communication with said combustion chamber and a second side in communication with a supply of a combustible mixture and having a plurality of ports through said valve member, said reciprocation of said floating valve member in said wall closing and opening communication through said ports between said supply of combustible mixture and said combustion chamber;
• means for supplying a pressurized combustible mixture to said second side of said floating valve member, said supply means having substantially smaller cross section area than said second side of said floating valve member;
• means for igniting and combusting said combustible mixture in said combustion chamber to produce pressurized combustion gases, said floating valve member being reciprocated by said pressurized combustible mixture in communication with said second side and said pressurized combustion gases in communication with said first side to regulate the flow of said combustible mixture into said combustion chamber.

A method for combusting a combustible mixture, comprising the sequential steps of:

• (a) supplying a pressurized combustible mixture to a first side of a floating valve member, said valve member being at a first location;
• (b) moving said floating valve member by said pressurized combustible mixture toward a second location thereby increasing communication between said combustible mixture supply and a combustion chamber through a plurality of ports through said floating valve member;
• (c) admitting said combustible mixture through said plurality of ports which direct said combustible mixture along the periphery of said combustion chamber when said floating valve member is moved from said first location;
• (d) combusting said combustible mixture in said periphery of said combustion chamber producing combustion gases;
• (e) moving said floating valve member toward said first location by the pressure of said combustion gases thereby decreasing communication between said combustible mixture supply and said combustion chamber through said plurality of ports;
• (f) venting a portion of said combustion gases through an unvalved vent to reduce the pressure of the combustion gases in the combustion chamber;
• and
• (g) repeating said steps.
