Abstract
Apparatus for igniting a main gas mixture to be burnt in a combustion chamber includes conduit systems for separately feeding an oxygen-bearing gas and a combustible gas into an ignition region. At least a part of at least one of the conduit systems is formed as an electrical heating resistance thereby to raise the temperature of the gas component flowing therein so that when the components are mixed in the ignition region, ignition of the ignition gas mixture will occur, thereby igniting the main gas mixture. The apparatus also includes means for detecting the temperature of the heated gas component or components flowing through the conduit systems, and/or the temperature of the gas mixture ignited in the ignition region.
Claims24
Apparatus for igniting a main gas mixture comprising:
- a first conduit system for feeding an oxygen-bearing gas component of a combustible ignition gas mixture to an ignition region;
- a second conduit system for feeding a combustible gas component of the ignition gas mixture to the ignition region, separately from the oxygen-bearing gas component, at least part of at least one of the conduit systems providing an electrical heating resistance means for heating the component flowing therein to a temperature adapted to cause ignition of the ignition gas mixture upon mixing thereof in the ignition region;
- means for detecting the temperature of at least one of the heated components, said means disposed within at least one of said conduits;
- means for alternatively connecting at least one of said conduit systems to a supply means for supplying inert gas;
- and
- means for switching over of said at least one conduit system in response to the temperature detecting means, from the inert gas supply means to the gas mixture component supply conduit when a temperature is reached at which ignition of the ignition gas mixture can occur.
