摘要： A system for measuring a fuel-oxidant equivalence ratio includes at least one wall defining a gas volume including fuel and air. A gas ionization source is configured to cause a formation of ions in the gas. A power supply is configured to output a time-varying voltage. A first electrode is disposed in the gas volume, operatively coupled to the power supply, and configured to carry the time-varying voltage. A second electrode is arranged to operatively couple to a signal output by the first electrode after the signal passes through the gas volume. Characteristics of the received signal indicate the fuel-oxidant equivalence ratio.

The heater includes gas burners 120A-120E, in which the gas is burned using oxygen admitted through the air inlets 110. One or more heat emitting elements 125A-125E are included, which emit infrared radiation using energy generated by the gas burners. One or more ionization probes 130A are provided proximal to two or more of the heat emitting elements for detecting the presence or absence of a flame. A housing 115 accommodates the gas burners, the heat emitting elements and the ionization probes. One or more control units are provided which are in electrical communication with the ionization probes and the gas inlets, the control units operable to shut off the gas supply if the ionization probes detect the absence of a flame.

摘要： A gas fire ember element comprises a bundle of wire of a heat and oxidation resistant metal (Fecralloy® or Nichrome®, for example). The density of wire in the bundle is so loose (between 0.01 and 0.1% by total volume of the bundle) that burning gas percolates through it. The wire has a filament cross section of between 500 μm2 and 8,000 μm2. so that it quickly glows and stops glowing as it is heated or not heated by flickering gas flame. The bundle can be hollow, said wire being confined to a surface region of the bundle having a thickness between 50 μm and 5,000 μm. Either the density of wire in the surface region is between 0.01% and 0.1% by total volume of the surface region, or a projection of the wire in the surface region occupies between 0.01% and 0.1% by total area of said projection. The wire in the surface region may be a mesh.
