  • Jet Impingement/Radiant Heating Apparatus

    view source
  • US Patent:
    43737021, Feb 15, 1983
  • Filed:
    May 14, 1981
  • Appl. No.:
    6/263630
  • Inventors:
    Viswanath Jayaraman - Livonia MI
    Carroll Cone - Toledo OH
  • Assignee:
    Holcroft & Company - Livonia MI
  • International Classification:
    C21D 956
  • US Classification:
    266111
  • Abstract:
    Heat-treating apparatus which includes an insulated furnace compartment through which stock to be heat-treated is passed. Perforated tubes are arranged in the furnace and they are heated to radiance by burners which also generate products of combustion which are ejected through the perforations at high velocity to impinge upon a surface or surfaces of the stock being heat-treated. The combination of radiation and convection enhanced by the impingement of the jets upon a surface of the stock provides highly efficient primary heat transfer. The burners are designed to insure that rapid combustion takes place at a point removed from the perforations to avoid flame issuing from the perforations. The tubes are sized and spaced to enhance secondary heat transfer from gases in the furnace compartment and from the walls of the compartment to the stock.
  • Water Heater With Thermoelectric Module And Through-Chamber Heat Sink

  • US Patent:
    54958296, Mar 5, 1996
  • Filed:
    Sep 14, 1994
  • Appl. No.:
    8/306128
  • Inventors:
    Viswanath Jayaraman - Brecksville OH
    David H. McFadden - Lexington MA
    Scott J. Hynek - Waltham MA
  • Assignee:
    Consolidated Natural Gas Service Company, Inc. - Pittsburgh PA
  • International Classification:
    F22B 912
  • US Classification:
    122110
  • 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.
  • Ceramic Radiant Tube Heated Aluminum Melter And Method Of Melting Aluminium

  • US Patent:
    44327919, Feb 21, 1984
  • Filed:
    Mar 4, 1983
  • Appl. No.:
    6/472425
  • Inventors:
    Viswanath Jayaraman - Livonia MI
    Mahendra R. Shah - Canton MI
  • Assignee:
    Holcroft & Company - Livonia MI
  • International Classification:
    C21C 2100
    F27B 326
  • US Classification:
    75 65R
  • Abstract:
    Disclosed are a method and apparatus for clean, low loss melting of aluminum using heat transfer by convection and radiation in separate stages. Heat input to a melter stage is provided by silicon carbide tubes into which gas-fueled burners fire so that the tubes radiate heat to a molten aluminum bath. Combustion products exiting the silicon carbide tubes pass through recuperators, preheating burner combustion air. The combustion products then are piped to a preheater stage and formed into jets of hot gases. The jets are directed into convective contact with solid aluminum stock as the stock is transported along a conveyor, preheating the stock to a temperature of about 1,000. degree. F. The solid stock then is fed to the charge zone of the melter stage and melted by contact with the molten bath.
