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.
Claims11
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, wherein the variable area device is located outside of the passage, wherein the variable area device is a mechanical iris, which comprises a first ring and a second ring, and a flexible material that is configured to twist open or closed based on a rotation of the second ring;
- and
- an actuator, wherein the actuator is configured to rotate the second ring to adjust a configuration of the variable area device, thereby adjusting the cross-sectional area of the passage.
