625,335. Liquid fuel burners. ROBINSON, N. R. March 17, 1947, No. 7346. Drawings to Specification. [Classes 75(i) and 75(iii)] [Also in Group XXVI] In a gas turbine plant, ignition is started by means of a torch burner and a sparking device which are automatically put out of action when the gases reach a predetermined temperature and are brought in again if combustion fails. The control solenoid of the torch burner and the primary of the spark coil are in parallel in a circuit which includes a switch controlled by a temperature sensitive device subject to the gases in the jet or exhaust tube or in a combustion chamber. The control is suspended when the plant is not in operation by means of a switch controlled by the engine speed, for example, through the pressure of the fuel supply, which is open when the turbine is not running and a switch on the pilot's control lever which is open when the lever is at " Stop." When the temperature-responsive device operates through electrical means, the supply circuit also includes the last-mentioned two switches.
