Abstract
A fuel regulator, such for use in a commercial boiler, can include a control valve plumbed between a source line and a feed line. The feed line can be coupled to a burner configured to burn fuel supplied thereto at a range of pressures and the source line can be coupled to a source of fuel configured to supply the fuel at a pressure higher than the range of pressures. One or more sensors can be configured to detect an operating level of the burner. One or more actuators can be configured to control the valve according to the sensor and thereby control a flame from the burner.
Claims20
A fuel regulator, comprising:
- a control valve plumbed between a source line and a feed line, wherein the feed line is coupled to a burner configured to burn fuel supplied thereto at a range of pressures and the source line is coupled to a source of fuel configured to supply the fuel at a pressure higher than the range of pressures;
- a sensor configured to detect an operating level of the burner;
- and
- an actuator configured to control the valve according to the sensor and thereby control the burner.
A fuel regulator, comprising:
- a control valve plumbed between a source line and a feed line, wherein the feed line is coupled to a burner configured to burn fuel supplied thereto at a range of flow rates and the source line is coupled to a source of fuel configured to supply the fuel at a flow rate higher than the range of flow rates;
- a sensor configured to detect an operating level of the burner;
- and
- an actuator configured to control the valve according to the sensor and thereby control the burner.
A regulator, comprising:
- a control valve plumbed between a source line and a feed line, wherein the feed line is configured to supply material to a consumer of the material and the source line is coupled to a source of the material;
- a sensor configured to detect an operational parameter of the consumer;
- and
- an actuator configured to control the valve according to the sensor and thereby control the consumer.
