  • Patent number: 8858223
    Abstract: A Glycerin Fueled Afterburning Engine utilizes the power generation unit exhaust heat to pre-heat the glycerin, or similar difficult to combust fuel, and then utilizes regenerative burner heating to fully vaporize and superheat the fuel above the auto ignition temperature. The combustion inlet air is also highly preheated by the recuperative power generation cycle. The actual combustion process is then accomplished by hypergolic ignition from mixing the hot vapor with the hot air. The overall engine process operates on a cycle of (1) air compression, (2) indirect heating of air in an air heater, (3) air expansion, (4) air heating by combustion, and (5) air cooling by heat transfer to the incoming compressed air charge in the recuperator.

  • Patent number: 7802984
    Abstract: A system and method for providing a gas-fired heating system with improved thermal efficiency includes modulating a quantity of combustion air flow to a combustion mixture in response to a measured change in fuel-gas pressure using a DC (e.g., brushless) motor to drive a combustion air blower. A pressure transducer in a manifold transporting fuel-gas into the combustion mixture outputs a signal proportional to the measured pressure to the motor. The motor speed and thus the resultant quantity of combustion air flow are modulated in proportion to the quantity of fuel-gas to the mixture. Accordingly, a constant fuel-gas to combustion air ratio is maintained. The system and method may further provide for adjusting the output signal to accommodate measured intake air temperature, and/or measured atmospheric pressure in order to maintain a constant, good thermal efficiency (preferably ?80%) regardless of air temperature and altitude at the system's installation location.

    Abstract: The invention is directed to an ignition control system that dynamically adjusts the warm-up time of an igniter within a predetermined range depending on the success or failure of the previous ignition or start-up cycle. The system activates the igniter and waits a predetermined or computed warm-up time. At the end of the warm-up time, the system opens a gas valve. The system then waits a preset time from the opening of the gas valve to determine whether ignition was successful or not. If the ignition was successful, the system computes a new igniter warm-up time by decrementing the current time and stores this new value for use during the next start sequence. If the ignition was unsuccessful, the system computes a new warm-up time by incrementing the current value and retrying the start sequence. Preferably, a successful ignition is always determined by checking for the presence of flame a fixed time following the opening of the gas valve.

  • Publication number: 20020055075
    Abstract: A gas operated lantern includes a regulator having a simple mechanism allowing a user to start or stop the flow of gas through the regulator. The regulator preferably exhausts an air/gas mixture in the same direction as which gas enters the regulator. The regulator includes a diaphragm assembly which presses down on a valve assembly to open the valve assembly. A stem enters the regulator and is turnable by the user to raise the diaphragm assembly and thus cause the valve assembly to close. The lantern also includes an automatic choke. The choke is preferably a strip of metal located in the burner tube of the lantern which acts to close off a portion of the burner tube when the lantern is cold, causing the air/fuel mixture to become richer and thus easier to light. As the lantern heats up, the choke straightens to open the burner tube, allowing a greater flow of air through the lantern and causing the air/fuel mixture to become leaner and thus raising the efficiency of the lantern.

Gases are forced into a firebox, where a heating element maintains a temperature above the flash point for the more common and undesirable pollutants. Typical temperatures are 500.degree. C. to 800.degree. C. for burning hydrocarbons coming from internal combustion engines or wood stoves. After gases pass through the firebox, they are forced into a chamber adjacent to the firebox intake, so that heat energy may be transferred to the incoming gases, thereby greatly increasing the thermal efficiency of the device. Greater efficiencies are achieved by putting a catalytic surface in the firebox, and by insulating the afterburner exterior.

  • Patent number: 4892476
    Abstract: An apparatus for controlling the combustion in a heater detects the temperature in a burner and selects a re-ignition mode for fuel dependent on the temperature in the burner. The apparatus controls an atomizing device which atomizes fuel in the selected re-ignition mode, and an igniting device which ignites the fuel atomized by the atomizing device.

  • Patent number: 4744747
    Abstract: A controller for a heater has two switch circuits for controlling the supply of electric power to an atomizing glow plug for atomizing fuel and an ignition glow plug for igniting atomized fuel, the glow plugs being connected parallel to each other. One of the switch circuits includes a series-connected resistor for producing a voltage drop thereacross. During an inital period of operation of the heater, the first switch circuit free of the series-connected resistor is turned on to heat the glow plugs quickly up to respective prescribed temperatures for atomizing and igniting the fuel. Upon elapse of a predetermined period of time, during which the prescribed temperatures are reached, the first switch circuit is turned off and the second switch circuit with the series-connected resistor is turned on to keep the glow plugs at the prescribed temperatures without further heating them.

  • Patent number: 4740154
    Abstract: This invention relates to a free flame burner with turbulent atomisation, which comprises a fuel oil feed pump, a combustion air feed fan and a compressor for feeding a fraction of the gaseous combustion products to a combustion chamber, wherein the fuel oil and said fraction of gaseous combustion products are fed, with mutually opposing rotary motion, to an atomiser nozzle in which the gas and fuel unite turbulently before being fed into the combustion chamber.

  • Patent number: 4431401
    Abstract: A vaporizing apparatus includes a vaporizing chamber for producing vapors from a hydrocarbon fuel which are drawn into a mixing chamber by pressurized air, and the mixture is delivered to a manifold where a portion is return to the vaporizing chamber and ignited for heating and vaporization, a safety control system sensing the presence of a flame and the temperature of the vaporization chamber and interrupts flow of vapors when the flame is absent or the temperature is outside prescribed limits. A starter burner which uses the hydrocarbon fuel as a combustible material for preheating the vaporizing chamber is also automatically shut off by the control system when the vaporization chamber reaches the operating temperature. The starter burner includes a mixing valve and a combustion chamber with mixing chamber therebetween for drawing ambient air into the mixture of pressurized air and combustible material.

  • Patent number: 4140473
    Abstract: An apparatus and method to control a process to replace natural gas with vaporized fuel oil whereby fuel oil is mixed with a gaseous diluent and partially vaporized, liquids separated out, superheated and burned in a natural gas burner without major modification to the burner is disclosed. The control system is:1. a liquid level controller sensing the liquid level in the separator to automatically control the flow of the fuel oil to the vaporizer,2. a ratio flow controller sensing the flow of the fuel oil and of the diluent to the vaporizer to automatically control the flow of the diluent to a set ratio of the flow of the fuel oil,3. a pressure controller sensing the pressure at the vaporizer outlet and downstream overhead to automatically control the heat input to the vaporizer and optionally,4. a flow control valve set to automatically control the flow of the separator overhead to the burner; also,5.

  • Patent number: 4081234
    Abstract: A control system that provides a safety limit and temperature control for an oil preheater used with oil burners that burn viscous grades of fuel oil. The control incorporates a first temperature sensor for control of a fuel oil heater and a second temperature sensing means to provide for a safe start check of an oil burner.The start is allowed only if the temperature of the oil is at or above the temperature required for proper operation of the fuel burner.
