A method of controlling combustion of a gas appliance includes the following steps: a) Read a first burning data in a database; b) Burn gas according to the first burning data; c) Obtain a burning efficiency of the gas appliance; and d) Compare the burning efficiency with a predetermined value, and repeat the step b to the step d when the burning efficiency is higher than the value, or read a second burning data in the database and burn gas according to the second burning data when the burning efficiency is lower than the value. The present invention provides plural stages of burning according to the main component of the gas to be burned to increase the total burning efficiency.

The present invention provides a pressure gauge for measuring a pressure of a source. The pressure gauge includes a case, a flexible film, a magnetic device, a coil, a processor, and a screen. The case has a bore connecting the source. The coil is provided in the case. The flexible film is provided on an inner side of the case to cover the bore that the flexible film is expandable by the pressure of the source. The magnetic device is received in the case to be moved relative to the coil by the flexible film. The movement of the magnetic device causes the coil to generate an induced electromotive force, and the processor may find the gas pressure according to the induced electromotive force, and show it on the screen.

A gas water heater includes a piping disposed in a housing for receiving a fluid to be heated, a gas burner for receiving a gaseous fuel and for generating a heat to heat the fluid flowing through the piping, and a regulating device coupled to the gas burner for adjusting the supplying of the gaseous fuel to the gas burner. A carbon dioxide detector is disposed in the housing for detecting the carbon dioxide or carbon monoxide generated by the gas burner, and a control device is coupled to the carbon dioxide detector for receiving the detected signal from the carbon dioxide detector and for operating the regulating device to adjust the supplying of the gaseous fuel to the gas burner and for allowing the gaseous fuel to be completely burned.
摘要:
A gas appliance includes a pilot burner, one or more main burners, a solenoid valve coupled to the pilot burner and the main burners for controlling the pilot burner and the main burners, and a control circuit coupled to the solenoid valve for controlling the solenoid valve to operate the pilot burner or the main burner remotely. An igniting device may be coupled to the control circuit for being operated by the control circuit to selectively ignite the pilot burner. One or more batteries may be coupled to the control circuit for energizing the control circuit, and a thermo-couple may be coupled to the control circuit for selectively energizing the control circuit when the battery is out of electricity.
