Definitions

  • the present invention refers to a gas radiator for heating, comprising a pilot burner and a main burner.
  • the gas radiators for heating comprise pilot burners that are used to guarantee the ignition of the main burners when there is a heat demand, without any manual or automatic additional ignition by a spark generator.
  • thermocouple The supervision of the flame carried out by a thermocouple is submitted permanently to the heat produced by the pilot burner.
  • pilot burners are formed by an injector of reduced dimensions, a primary air input and a burner head, that provides a flame that guarantees the ignition of the main burner.
  • the drawback that the conventional radiators have is that the flame of the pilot burner can be extinguished easily if it is subjected to air draughts, if it is not very protected, e.g. when the radiator is used outdoors .
  • the gas radiator of the present invention comprises at least a main burner and a pilot burner, said pilot burner guaranteeing the ignition of the main burner, and it is characterised in that said pilot burner is an infrared radiation burner.
  • said pilot burner of infrared radiation comprises a Venturi tube placed between a gas injector and a combustion chamber.
  • said Venturi tube comprises an air filter placed around it.
  • said combustion chamber is formed from a refractory stainless steel plate or other refractory material provided with a plurality of holes.
  • said air filter is preferably formed from a metallic mesh.
  • Fig. 1 is an elevation view of the radiator of the present invention sectioned
  • Fig. 2 is an elevation view of the pilot burner of the radiator of the present invention sectioned.
  • the gas radiator of the present invention comprises a main burner, identified generally by reference numeral 1, and a pilot burner 2.
  • the pilot burner 2 guarantees always the ignition of the main burner during the operation mode and reduces the consumption, and it enhances therefore the energy efficiency of the radiator.
  • Said main burner 1 comprises an elbow Venturi tube 3 connected with the gas input 4, a shade 5 and a combustion chamber, that it is formed by an external cone 6 and an internal cone 7.
  • the external cone 6 and the internal cone 7 are made from a perforated plate of refractory steel or other refractory material. This main burner 1 provides the heat enough to the radiator to carry out its heating function.
  • pilot burner 2 is an infrared radiation burner, and it can been seen better in
  • Fig. 2 comprises a gas injector 8 connected with the gas input 9, said injector 8 comprising a gauged hole that provides the gas necessary to produce the combustion.
  • the pilot burner 2 also comprises a Venturi tube 10 and a combustion chamber 11.
  • the Venturi tube 10 is a mixer of gas and air, so that the gas injected inside the Venturi tube 10 generates a depression that induces the flow of primary air needed to the fuel mixture.
  • said combustion chamber 11 has a conical shape and is made from a refractory stainless steel plate or other refractory material, son a very fine holes distributed proportionally on its surface, which guarantee the stability of the flame and that the temperature of infrared radiation can be reached.
  • the pilot burner 2 also comprises an air filter
  • the pilot burner 2 comprises a thermocouple 13, which produces a little electrical voltage enough to keep the security valve open, if the pilot burner 2 is switched-on.
  • the radiator of the present invention is specially designed for its use as heater for zootechnics, terraces, workshops and places generally outdoors.
  • the pilot burner 2 of infrared radiation is of atmospheric kind, and it is based in the infrared radiation principle.
  • the combustion is carried out by the mixture of gas and air that crosses the Venturi tube 10. This mixture, when contacts with the secondary air, burns on the refractory stainless steel surface or other refractory material of the combustion chamber 10. This surface is at a temperature above 800 0 C, so that all the combustion mixture that contacts the surface burns, guaranteeing the ignition of the main burner with safety conditions.

Abstract

L'invention concerne un radiateur à gaz qui comprend au moins un brûleur principal (1) et un brûleur pilote (2), ledit brûleur pilote (2) garantissant l'allumage du brûleur principal (1), et qui est caractérisé par le fait que ledit brûleur pilote (2) est un brûleur à rayonnement infrarouge. Ledit brûleur pilote (2) de rayonnement infrarouge comprend, de préférence, un tube Venturi (10) placé entre un injecteur de gaz (8) et une chambre de combustion (11). Il permet une grande stabilité de l'allumage dans des conditions de courants d'air, une consommation inférieure à celle d'un pilote traditionnel, et une résistance supérieure contre la poussière, la saleté et des conditions environnementales préjudiciables.
