  • Publication number: 20140186780
    Abstract: Methods and systems for controlling jet velocity of a preheated gas are described herein. Through the use of a temperature-sensitive bimetallic valve, the flow of a gas can be redirected to maintain jet velocity based on temperature. The temperature-sensitive bimetallic valve can redirect flow of the gas based on the position of a bimetallic strip. The bimetallic strip and a connected blocking device can change position based on the temperature of the gas. The position of the bimetallic strip and the blocking device control the size of the port that the gas is delivered to the burner through. Thus, preheated gas and standard temperature gas can be delivered at appropriate velocities based on the needs of the user.

  • Publication number: 20140186781
    Abstract: Methods and systems for controlling jet velocity at a burner when using heated gases and standard temperature gases are described herein. Through the use of a temperature-sensitive magnetic valve, the flow of a gas can be redirected to reduce velocity based on temperature. The temperature-sensitive magnetic valve can redirect flow of the gas based on the magnetic state of a curie material. The curie material changes the state of the temperature-sensitive magnetic valve based on the temperature of the gas. Thus, heated gases and standard temperature gases can be delivered at approximately equal velocities thus maintaining flame size and shape.

  • Patent number: 8702420
    Abstract: In one embodiment of a method for vaporizing liquids such as fuels, the liquid is sprayed into a chamber such that the spray does not impinge on any surface. The energy for vaporization is supplied through the injection of a hot diluent such as nitrogen or oxygen depleted air. Additional heat is added through the surface. In another embodiment, the liquid is sprayed onto a hot surface using a geometry such that the entire spray is intercepted by the surface. Heat is added through the surface to maintain an internal surface temperature above the boiling point of the least volatile component of the liquid. The liquid droplets impinging on the surface are thus flash vaporized. A carrier gas may also be flowed through the vaporizer to control the dew point of the resultant vapor phase mixture.

  • Patent number: 8695515
    Abstract: A method for burning raw materials by which method the raw material and a secondary fuel are separately introduced to one and the same rotary kiln in which the raw material as well as the secondary fuel are heated by gases formed by burning of a primary fuel in the rotary kiln so that the secondary fuel is converted to gases and solid matter in the form of combustion residues such as ashes and coke. The secondary fuel during the process of conversion to gases and solid matter is kept separate from the introduced raw material, which may ensure that the secondary fuel and hence the locally reducing zones and major areas with reducing conditions are brought into minimum contact with the raw material.

  • Publication number: 20140080073
    Abstract: A combustion system for operational connection to an energy conversion system and a method of providing thermal energy to the energy conversion system. The system comprises a combustor to be oxy-fired at above atmospheric pressure, using solid, liquid or gaseous fuels, with a supply of oxygen and supercritical carbon dioxide. The combustion gases from the combustor are delivered to a heat exchanger which interfaces with the energy conversion system. Temperatures in the combustor, and the delivery temperature to the heat exchanger, are controlled by selective recirculation of at least part of the combustion gases to the combustor, and by modulating the supply of oxygen and fuel to the combustor. Any combustion gases which are not recirculated are processed to separate carbon dioxide for use or sequestration. The system and method substantially eliminate emissions of carbon dioxide, while providing a highly efficient supply of thermal energy to the energy conversion system.
