Abstract
The disclosed technology includes a device for extending the turndown ratio of a gas-fired burner system. The device can comprise a variable area device configured reduce the amount of fuel and air passed to the burner during low output conditions by adjusting the cross-sectional area of the passage between the blower and the burner. The variable area device can be controlled by an actuator that adjusts the position of the variable area device. The actuator can be manually controlled, mechanically controlled, or electronically controlled.
Claims20
A device for extending a turndown ratio of a gas-fired burner system, the device comprising:
- a variable area device configured to adjust a cross-sectional area of a passage between a blower outlet of the gas-fired burner system and a burner inlet of the gas-fired burner system;
- and
- an actuator, wherein the actuator is configured to adjust a configuration of the variable area device, thereby adjusting the cross-sectional area of the passage.
A method for extending a turndown ratio of a gas-fired burner system, the method comprising:
- receiving, at a controller, system data indicative of a gas-fired burner's performance;
- determining, by the controller and based on the system data, to adjust a variable area device from a first configuration to a second configuration;
- and
- transmitting, by the controller, instructions to an actuator to adjust the variable area device from the first configuration to the second configuration.
A gas-fired burner system, the system comprising:
- a blower;
- a burner;
- a variable area device configured to adjust a cross-sectional area of a passage fluidly connecting the blower to the burner;
- an actuator;
- and
- a controller comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, direct the controller to:
- receive output data of the gas-fired burner system;
- and
- output a control signal to adjust a cross-sectional area of the variable area device in response to determining that the output data indicates that the gas-fired burner system has reduced its output.
