  • Publication number: 20230296264
    Abstract: An apparatus and method for producing heat and electricity independent of an electrical grid. The apparatus includes a burner adapted to produce at least one of radiant heat, flame and hot combustion gases. A thermal-to-electric conversion device is integrated with the burner and proximate to the burner, for producing electricity. The conversion device has a first side disposed toward the at least one of radiant heat, flame and hot combustion gases and a second side disposed toward and in heat transfer contact with a liquid supply line. The apparatus is useful in water heaters. The liquid supply line provides both water to be heated and a cooling medium for the thermal-to-electric conversion device.

  • Patent number: 11226092
    Abstract: Methods and combustion devices for reducing NOx formation upon combusting oxidant with fuel to form products of combustion are provided. Such methods and device may involve mixing at least first portions of at least two fluids selected from the group of oxidant, fuel and recirculated products of combustion in at least one first conduit to form a first mixture. The first mixture is subsequently supplied to a plurality of second conduits each in direct fluid communication with the first conduit. Motive energy is utilized to aspirate at least second portions of one or more fluids selected from the group of oxidant, fuel and recirculated products of combustion in at least one second conduit to form a combustible mixture that can be subsequently burned. In one embodiment, the motive energy may be provided or result from the first mixture.

  • Patent number: 10488039
    Abstract: Methods of burning combustible gas mixtures on a surface of a permeable matrix providing surface stabilized combustion (SSC) with increasing amounts of radiation energy emitted by the surface of the permeable matrix and decreasing concentrations of pollutant components in the combustion products are provided. The gas mixture is fed to a burner that includes a permeable matrix material having a first thermal conductivity. The gas mixture is preheated as it travels through the permeable matrix material. The gas mixture is then combusted at or near exit pores and channels formed at a combustion surface of the permeable matrix material, the combustion surface at least in part coated with a coating material having a thermal conductivity less than the permeable matrix material thermal conductivity and a high optical transmittance in the infrared spectrum.
