  • Metallic burner tiles
    Patent number: 11885489
    Abstract: The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.
    Type: Grant

  • Furnace tube radiants
    Patent number: 10808181
    Abstract: A substantially linear ceramic or metallic radiant of ellipsoidal or polygonal cross section is placed proximate furnace tubes or coils in the radiant section of a fired heater to increase the radiant heat directed to the surface of the tubes or coils.

  • Pinned furnace tubes
    Patent number: 10167431
    Abstract: Furnace tubes for cracking hydrocarbons that in an embodiment have a longitudinal array of pins having i) a maximum height from about 2 to about 4.8 cm; ii) a contact surface with the tube, having an area from about 0.1% to about 10% of the tube external cross section area iii) a uniform cross section along the length of the pin. (i.e., they are typically not tapered); and iv) a length to diameter ratio from about 4:1 to about 2:1 have an improved heat transfer over bare fins and reduced stress relative to a fined tube.

  • Pinned furnace tubes
    Patent number: 10000707
    Abstract: In an embodiment of the invention, furnace tubes for cracking hydrocarbons having a longitudinal array of pins having i) a maximum height from 0.5-1.3 cm; ii) a contact surface with the tube, having an area from 0.1%-10% of the tube external surface area iii) a uniform cross section along the length of the pin. (i.e. they are not tapered); and iv) a length to diameter ratio from 1.5:1 to 0.5:1 have an improved heat transfer over bare fins and reduced stress relative to a fined tube.

  • FURNACE COIL MODIFIED FINS
    Publication number: 20170343301
    Abstract: The present disclosure provides for thick fins on the surface of coils or tubes in a steam cracking furnace. The fins have a thickness at their base from ¼ to ¾ of the radius of the furnace tube. The fins have grooves or protuberances on not less than about 10% of a major surface. The fins help increase the radiant heat taken up by the tube from the walls and combustion gases in the furnace.
