  • Patent number: 7568911
    Abstract: A stove has a fuel tank with a flat top and bottom and a side wall to define a fuel chamber. A fuel feed path includes a vertical pipe assembly. The fuel feed path also includes a horizontal pipe assembly functioning as a vaporizer. The fuel feed path also includes a generally C-shaped pipe assembly. An associated warming coil is in a generally circular configuration to direct a flow of some of the fuel from one part of the horizontal pipe assembly to another part of the horizontal pipe assembly. A generally cylindrical ignition chamber is at the terminal end of the C-shaped pipe assembly. Apertures are provided for cooking purposes and are adapted to preheat the fuel in the horizontal pipe assembly and the warming coil.

  • Patent number: 6095793
    Abstract: A unique and useful dynamic control system has been invented for the control of a catalytic combustion system for use on a dynamic plant, preferably, a gas turbine engine. The dynamic control system facilitates the replacement of conventional flame combustion systems with catalytic combustion systems, which produce far less pollutants, by producing acceptable transient performance of the combustion system. A method of controlling the catalytic combustion process comprises the steps of calculating a mass flow of air introduced into the combustor, monitoring a flow of fuel to be combusted within the combustor, monitoring a temperature of the air introduced into the combustor, calculating an inlet temperature set point based on the mass flow and fuel flow, and controlling a pre-burner to heat the air based on the inlet temperature set point, the mass flow, and the temperature of the air. Further, the mass flow may be estimated based on ambient air temperature and pressure, and compressor speed.

  • Patent number: 5567142
    Abstract: A burner system for a radio-controlled hot air balloon. The frame that is connected to an envelope contains two fuel tanks. One fuel tank is disposed right side up and delivers fuel in vapor form to a pilot burner mechanism. The other fuel tank is inverted and delivers in liquid form to a burner coil means. The flame of the pilot burner mechanism partially heats the liquid fuel in the burner coil means so that when a valve member is opened, fuel in a vaporous mist form is discharged from an outlet orifice of the burner coil means for ignition by the flame of the pilot burner mechanism. A radio-controlled servo is connected to the valve member and operates the same.

  • Patent number: 5495829
    Abstract: A self-powered forced or induced draft water heater is provided including a tank adapted for storing hot water, a sealed combustion chamber, a powered burner, a thermoelectric module, and a through-chamber heat sink having a base portion and a pin portion. The combustion chamber has a common wall with the tank at a lower zone of the tank. The powered natural gas burner has a blower which delivers air to the burner through an inlet duct and forces combustion products out a flue. The thermoelectric module generates operating power for the burner blower. The thermoelectric module has a hot side in thermal communication with a combustion zone of the burner and a cold side attached to the heat sink base portion. The pin portion of the heat sink is conically shaped and extends through an opening in the common wall to the interior of the tank. The base portion of the heat sink is removably attached to the common wall and is provided with an o-ring or other means to seal the wall opening.

  • Patent number: 5232358
    Abstract: A combustion apparatus comprises: a large-diameter sleeve-like element forming an incoming passage through which an air/fuel mixture gas flows in a predetermined direction; at least one small-diameter sleeve-like element disposed in the incoming passage, which small-diameter sleeve-like element forms an outgoing passage through which a combustion gas having been issued from the incoming passage flows in a direction counter to the above predetermined direction; an air/fuel mixing unit for issuing the air/fuel mixture gas under a predetermined pressure to a main incoming port located in an upstream side of the incoming passage; an auxiliary incoming unit for issuing a combustion gas produced by a pilot burner to the upstream side of the incoming passage prior to supplying the air/fuel mixture gas to the incoming passage; and a combustion-gas outlet port for discharging the combustion gas having passed through the outgoing passage, which combustion-gas outlet port communicates with an outlet opening of the outgo

  • Patent number: 5033957
    Abstract: Diesel fuel is vaporized and then burned on a cylindrical screen flame holder. The fuel is vaporized in a finned, vertical tube vapor generator and directed through a superheater tube past the flame to a flow control valve and nozzle. A flow restriction is provided between a liquid fuel supply and the vapor generator. The flame holder is vertically supported over a mixer and the nozzle. A flame deflector about the flame holder and a reservoir about the nozzle collect fuel condensate during start-up.

  • Patent number: 4529375
    Abstract: A fuel gasifying burner including a combustion device located below a portion of a gas generating member housing a fuel supply device for directing a supply of liquid fuel into the interior of the gas generating member. A plurality of combustion members formed with flame apertures at their surfaces are arranged on either side of the gas generating member substantially in the same horizontal plane or in a plane below that of the gas generating member and maintained in communication with the gas generating member. The combustion members may be one in number and annular in form and located below the gas generating member or of a torus shape to allow the gas generating member to extend through its center opening.

  • Patent number: 4231731
    Abstract: An automatic self-regulating burner system. A serpentine pipe structure connected to a source of fuel has a preheating portion, an orifice pipe portion and a backpressure pipe portion. The orifice pipe portion has an orifice therethrough which exhausts vaporized fuel. The exhausted fuel vapor is burned to heat both the preheater pipe portion for vaporizing and preheating the fuel, and the backpressure pipe portion for generating an internal pressure which automatically regulates the quantity of fuel vapors which are exhausted from the orifice.

  • Patent number: 4131414
    Abstract: A cup is provided adjacent the generator tube of a kerosene lantern for holding a measured amount of fuel. A wick is located in the cup for burning the fuel at a controlled rate. A foraminous housing extends around and above the wick to control the entrainment of air with the fuel from the wick during burning and to direct the resulting flame against the generator tube thereby preheating fuel in the generator tube to its vaporization temperature until the heat of combustion of fuel at the mantle causes the vaporization of fuel in the generator to be self-sustaining.
