  • Radiant tube furnace and method of burning a fuel
    Patent number: 5059117
    Abstract: A radiant tube furnace has a pair of regenerative burners firing alternately into opposite ends of the tube. There is a respective inlet at each end of the tube for admitting gas to the tube immediately adjacent to the wall thereof and these inlets communicate via a duct so that products of combustion are drawn from one end of the tube and introduced into the opposite end of the tube, where the burner is firing.

  • Method of operating a pair of burners and apparatus for use in the method
    Patent number: 4898530
    Abstract: A pair of regenerative burners is provided with feed means (25) for feeding a reducing agent into the products of combustion so that this agent can reduce oxides of nitrogen in the heat store to which heat is imparted by the products of combustion. Refractory elements (17,21) comprised by the heat stores may additionally or alternatively have catalytically active surfaces to promote reaction of the lower oxides of nitrogen.

  • Flow regulating device
    Patent number: 4626194
    Abstract: Means for supplying liquid or gaseous fuel to a burner includes a flow regulating device having three coaxial diaphragms, between each adjacent pair of which there is defined a chamber, these chambers being connected with respective sensing stations in an air flow path to the burner. Outer faces of the outer diaphragms are subjected respectively to pressures derived from sensing stations in the fuel flow path and the diaphragms are connected with one another and with a valve for controlling the rate of flow of fuel.
