  • Patent number: 11054141
    Abstract: A steam-based faux fireplace comprising a boiler configured to receive a fluid and generate steam, and a manifold configured to receive the steam from the boiler and emit the steam to generate a steam plume at an output. The manifold has a conduit configured to route the fluid about the manifold to heat the fluid before being routed to the boiler. The manifold is already heated due to the emitted steam. This configuration pre-heats the fluid before being presented to the boiler, allowing a smaller low power boiler to be used because the manifold acts as a fluid pre-heater. A very realistic faux flame with a significant length is generated from the low power boiler. In addition, the manifold includes a deflector configured to receive the impinging steam from the output, causing the steam to lose some energy and billow about the deflector and then illuminated to create a realistically looking flame.

  • Patent number: 11035259
    Abstract: A method of recovering heat from an exhaust stream during a manufacturing process is provided. The method includes providing a condensing heat exchanger having a first side with cold recirculation water and a second side; passing an exhaust stream of vapors having a temperature of 500 degrees F. or less into the heat exchanger through the second side. Heat from the exhaust stream is transferred to the first side of the condensing heat exchanger and the vapors are thus cooled to the dew point to cause condensation. The condensation is collected in a condensate tank where an amount recovered is from 20% to 75%. The condensate water is transferred to a flash tank and used to adjust the volume of the recirculation water routed thereto. External make-up water is input into the flash tank but is reduced by the amount of condensate water recovered by the heat stack recovery system.
