FUEL GAS COMPOSITION SENSING SYSTEM

摘要

A fuel gas composition sensing system may include a remotely controllable valve, with the valve including a gas inlet port, a gas outlet port, an internal chamber, and at least one actuating mechanism configured for successively opening the inlet port to allow gas to enter the internal chamber, closing the inlet port and the outlet port to retain the gas in the internal chamber for a period of time, and opening the outlet port to release the gas from the internal chamber. One or more micro-sensors may be mounted in the internal chamber of the valve, with each of the micro-sensors being configured to sense a characteristic of a gas introduced into the internal chamber of the valve. One or more heating elements may be mounted in the internal chamber, with each of the heating elements being associated with one of the one or more micro-sensors, and the one or more heating elements may be configured to implement a different temperature level at each of the micro-sensors in order to enable detection of a resulting change in the characteristic of the gas corresponding to a thermodynamic property of the gas that correlates to a composition of the gas.
