Abstract: The disclosed technology includes a fluid heating device including a frustoconical combustion chamber and a heat exchanger that can include heating tubes. The combustion chamber can have a first end and a second end that is in fluid communication with the heating tubes. The surface area of the second end of the combustion chamber can be larger than the surface area of the first end of the combustion chamber.

Abstract: Systems and methods for dynamic boiler control are disclosed. The system can receive flue gas data from a flue gas sensor and can receive blower data associated with a blower of the boiler. The system can determine, based at least in part on the blower data, a current fire status of the boiler and can provide one or more fire-status-specific parameters based on the current fire status of the boiler. The system can compare the flue gas data to a target flue gas value, and in response to determining that the flue gas data is less than the target flue gas value, the system can execute one or more boiler operation rules using the one or more fire-status-specific parameters. The system can output instructions for adjustment of an air-fuel ratio of the boiler based on the boiler operation rules and the one or more fire-status-specific parameters.

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.

Abstract: A baffle for a fluid collection portion of a thermal transfer device can include a body having an inner perimeter, an outer perimeter, and an asymmetric feature, where the asymmetric feature is configured to create a pressure drop within the fluid collection portion of the thermal transfer device. The inner perimeter can be configured to be at least as large as an inner surface of a first wall that forms the fluid collection portion of the thermal transfer device. The outer perimeter can be configured to be no larger than an outer surface of a second wall that forms the fluid collection portion of the thermal transfer device.
