  • Fire suppression system
    Patent number: 5607021
    Abstract: In a typical industrial boiler installation the hot exhaust gases are directed through a conduit to a thermal heat exchanger where a closed circuit exchanger carries a flammable fluid such as oil. Located within this section is a plurality of liquid spray nozzles which, upon detection of a fire, spray an amount of cool liquid into the hot gas stream which flashes to steam, thereby cooling the equipment and suppressing the fire by supplanting the oxygen within the gas stream.
