Abstract
The disclosed technology includes a gas delivery system for controlling a target gas input rate of a fluid heating device. The system can include a sensor configured to measure a temperature of a gas flowing in a gas flow path, a modulating orifice in fluid communication with the gas flow path, and a motor in mechanical communication with the modulating orifice. The system can further include a controller configured to receive temperature data indicative of the temperature of the gas. The controller can determine a target cross-sectional area of the modulating orifice based at least in part on the target gas input rate and the temperature of the gas and, in response, output a signal to the motor to transition the modulating orifice from a first position to a second position having the target cross-sectional area.
Claims20
A gas delivery system for controlling a target gas input rate of a fluid heating device comprising:
- a sensor in fluid communication with a fuel gas flowing in a gas flow path, the sensor configured to measure a temperature of the fuel gas;
- a modulating orifice in fluid communication with the gas flow path;
- a motor in mechanical communication with the modulating orifice;
- and
- a controller in communication with the sensor and the motor, the controller configured to:
- receive, from the sensor, temperature data indicative of the temperature of the fuel gas;
- determine a target cross-sectional area of the modulating orifice based at least in part on the target gas input rate and the temperature data;
- and
- in response, output a signal to the motor to transition the modulating orifice from a first position having a first cross-sectional area to a second position having the target cross-sectional area.
A gas delivery system for controlling a target gas input rate of a fluid heating device comprising:
- a sensor in communication with a fuel gas flowing in a gas flow path, the sensor configured to measure a temperature of the fuel gas;
- an electronic valve in fluid communication with the gas flow path;
- and
- a controller in communication with the sensor and the electronic valve, the controller configured to:
- receive, from the sensor, temperature data indicative of the temperature of the fuel gas;
- determine a target cross-sectional area of an orifice of the electronic valve based at least in part on the target gas input rate and the temperature data;
- and
- output a signal to the electronic valve to transition the orifice from a first position having a first cross-sectional area to a second position having the target cross-sectional area.
A non-transitory, computer-readable medium storing instructions, that when executed by one or more processors, cause a controller of a gas delivery system to:
- receive, from a sensor, temperature data indicative of a temperature of a fuel gas;
- determine a target cross-sectional area of a modulating orifice based at least in part on a target gas input rate and the temperature data;
- and
- output a signal to a motor to transition the modulating orifice from a first position having a first cross-sectional area to a second position having the target cross-sectional area.
