  • Publication number: 20070287111
    Abstract: A variable demand radiant heating system applies variable burner control technology to singular or multi-burner radiant heating systems. A radiant heater consists of a burner connected to an elongated heat exchanger tube. The combustion air is supplied to the burner via blower or draft inducer. Fuel is supplied to the burner via fuel regulator. Fuel and air are mixed in burner and communicated to the inlet end of the heat exchanger tube. Spent products of combustion are expelled from the heat exchanger at the outlet end. The burner controls continuously vary gas supply pressure (volume), via a modulating gas regulator, and combustion air pressure (volume), via a variable speed blower, communicated to the burner mixing chamber, which in turn, varies the burner input on a continuous curve (not stepped or staged) within a pre-determined input range as heat demand varies.

  • Publication number: 20060169275
    Abstract: A variable demand radiant heating system applies multi stage burner control technology to singular or multi-burner radiant heating systems. A radiant heater consists of a burner connected to an elongated heat exchanger tube. The combustion air is supplied to the burner via blower or draft inducer. Fuel is supplied to the burner via fuel regulator. Fuel and air are mixed in burner and communicated to the inlet end of the heat exchanger tube. Spent products of combustion are expelled from the heat exchanger at the outlet end. The burner controls provide gas supply pressure (volume), via a multi-stage or modulating gas regulator, and combustion air pressure (volume), via a combustion air blower with a plurality of operating speeds, communicated to the burner mixing chamber, which in turn, varies the burner input between two or more inputs that are stepped or staged within a pre-determined input range as heat demand varies.

    Abstract: A variable demand radiant heating system applies variable burner control technology to singular or mulit-burner radiant heating systems. A radiant heater consists of a burner connected to an elongated heat exchanger tube. The combustion air is supplied to the burner via blower or draft inducer.

  • Patent number: 6481434
    Abstract: A gas fired infrared radiant heating system of improved thermal output. The present invention solves problems associated with prior art designs by providing a single gas delivery system for delivering combustible gas to two or more burner assemblies. The invention consists of a burner housing (10) with two or more burner assemblies (18), each of which can be connected to a typical radiant tube heat exchanger assembly (12). The burner housing contains a single gas delivery system including a valve (14), a single control circuit module (30), a single blower proving switch (50), and a single manifold (16) which will distribute the gas to the multiple radiant tube heat exchanger assemblies (12). In addition, in positive pressure configurations, the burner housing will also have a single air fan (38), whereas in negative pressure configurations of the heating system one or more exhaust fans may be utilized.
