Definitions

  • This invention relates to a radiant tube heater assembly.
  • the conventional radiant tube heater includes a housing containing a burner, a burner tube extending out of the housing and a reflector connected to the housing and partially surrounding the burner tube. Gas is introduced into the burner for mixing with air from a blower attached to or mounted in the housing. The gas flows into the housing via an inlet line equipped with a valve.
  • a radiant tube heater is known, for example, from EP 1318354 A . It is necessary to control the flow of gas and air in order to ensure complete combustion of the gas. Otherwise, excess air, i.e. air not required for complete combustion of the fuel enters the burner tube with the flame from the burner and cools the combustion gases immediately downstream of the burner. Thus, when the supply of fuel to the burner is reduced, it is also necessary to decrease the blower fan speed so that less air is fed into the housing.
  • the object of the present invention is to provide a radiant tube heater assembly, which does not require a reduction in air flow when the heat is turned down, i.e. when the flow of gas into the burner is reduced by partly closing the valve in the gas inlet line or by the reduction of fuel pressure in the gas valve and/or gas regulator assembly.
  • the above defined object is achieved by adding a short flame tube in the inlet end of the burner tube so that air not required for complete combustion of the gas flows over the flame tube. During passage over the flame tube, the air is heated and then mixes with the combustion gases downstream of the flame tube. Consequently, the combustion gases are not cooled or are cooled less than in existing burner tubes without a flame tube.
  • the invention relates to a radiant tube heater comprising a housing; an opening in one end of said housing; a burner; a gas inlet extending into said housing and connected to said burner for introducing fuel into said burner; a blower in said housing for introducing combustion air into the housing for mixing with the fuel; and a flame tube, wherein the burner is located completely inside of the housing and a burner tube extends outwardly from said housing around said opening, the blower blowing a flame and the products of combustion into said burner tube and the flame tube being provided in said burner tube for receiving the flame, the arrangement of the burner tube and the flame tube being such that air required for complete combustion of the gas passes through the flame tube, and excess air exiting the housing passes between the burner tube and the flame tube for heating by the flame tube.
  • a radiant tube heater assembly includes a housing 1 with a burner tube 2 extending outwardly therefrom.
  • a reflector (not shown) is usually provided around the top and sides of the burner tube 2.
  • the interior of the housing 1 is divided into a pair of chambers 3 and 4 by a partition 5.
  • the chamber 3 contains a blower 6 for introducing combustion air into the chamber 4 and the inlet end 8 of the burner tube 2. Gas is fed into a burner 9 in the chamber 4 via an inlet line 10 containing a valve 11.
  • a short flame tube 15 is mounted in the inlet end 8 of the burner tube 2 for receiving the flame 12.
  • the flame tube 15 can be spot welded to one side (in this case the bottom) of the burner tube 2.
  • the burner 9 is aligned with the longitudinal axis of the flame tube 15.
  • the burner 9 is centered with respect to the opening 12 in the housing 1 and the longitudinal axis of the burner tube 2.
  • the flame tube 15 is mounted in the center of, i.e. is concentric with, the burner tube 2.
  • Short rods 16 are used to connect the flame tube 15 to the burner tube 2.
  • Other rods 17 at the outlet end of the flame tube 15 help to maintain the tube centered in the burner tube 2.
