Abstract:
An entirely pneumatic feedback signal can be generated within a gas delivery system by diverting the portion of the gas from the main supply line to a cryostat. The gas is cooled in the cryostat and flows within a restricted passageway defined by the cryostat itself. The output of the cryostat is then coupled to the control port of a actuatable pneumatic valve. The actuatable pneumatic valve is coupled in series in the supply line and is normally biased closed. However, upon application of a predetermined magnitude of pressure to the control port of the actuatable valve, the valve is maintained in a open configuration. The output of the cryostat is provided to the control port of the valve. A fixed orifice is pneumatically communicated to the output of the cryostat and vents the cryostat's output into the environment. As long as the gas continues to flow freely through the cryostat the valve remains open.

Abstract:
In direct fired fluid burner heater of the type where fuel is continuously injected and burned at one end of a cylindrical combustion chamber and combustion gases discharged at an opposite open end pass through a heat exchanger for heating a circulating medium, and where high heat capacity is achieved for a given chamber size by swirling the flame in the combustion chamber, acoustical low frequency buzzing is controlled by restricting the discharge area through which exhaust gases flow downstream of the heat exchanger.
