Combustion air proving apparatus with burner cut-off capability and method of performing the same
A combustion air proving (CAP) system for a burner assembly having a burner for providing heated air to a location, a controller, and a back plate, where outside air is fed to the burner via a conduit. The CAP system, is connected to an inlet of the system. An outlet of the system is connected to the burner via the back plate. A damper within the system is translatable between open and closed positions for allowing and blocking air flow, respectively. A sensor measures an air flow parameter of air flow to the burner. The sensor communicates with the controller, which shuts down the burner if the parameter measured by the sensor meets a predetermined threshold value. An assembly installer may test for proper sensor and controller functions by translating the damper to the closed position and blocking outside air flow.

System and method for safer venting of hydrogen or other combustible gases
A system and process for intermittently venting combustible gas (c-gas) from a continuous source to the atmosphere are presented. The system includes a primary c-gas storage tank, at least one primary admission valve located upstream of the primary c-gas storage tank for regulating the flow of c-gas from the continuous source to the storage tank, a primary valve for atmospheric venting located downstream of the primary c-gas storage tank, and a primary PIC that opens the primary valve for atmospheric venting when pressure in the primary c-gas storage tank reaches a pre-determined PIC vent point. The system may include an auxiliary system to receive and vent c-gas while the primary admission valve is closed. The primary and auxiliary systems may also include an inert gas storage tank and inert gas valve for diluting the c-gas before it is vented to the atmosphere.

DEVICE FOR REGULATING A MIXING RATIO OF A GAS MIXTURE
A regulation device for regulating a mixing ratio (x) of a gas mixture comprises a first conduit (1) for carrying a flow of a first gas (e.g., air) and a second conduit (2) for carrying a flow of a second gas (e.g., a fuel gas). The first and second conduits (1, 2) open out into a common conduit (3) in a mixing region (M) to form the gas mixture. A first sensor (S1) is configured to determine at least one thermal parameter of the gas mixture downstream from the mixing region. A control device (10) is configured to receive, from the first sensor, sensor signals indicative of the at least one thermal parameter of the gas mixture and to derive control signals for adjusting device (V1) acting to adjust the mixing ratio, based on the at least one thermal parameter.
