An exhaust-gas tract for a motor vehicle has an exhaust-gas burner that includes an air inlet connection for the introduction of air into the exhaust-gas burner. The air inlet connection has a connection piece in which a check valve for the closure of the connection piece is arranged. The air inlet connection has an air inlet flange which connects the connection piece to a combustion chamber of the exhaust-gas burner and which seals off the combustion chamber. A motor vehicle incorporates the exhaust-gas tract.

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.

A firebox for an outdoor cooking system has a gas burner positioned inside the firebox housing. The gas burner has a built-in altitude adjustment mechanism that allows for adjustment of proper air/gas mixture for cooking at different altitudes. An air deflector configured as an enclosing wall encloses the gas burner so as to greatly reduce the flow of unwanted air/wind disruptions to the flame/heat output of the gas burner.

An air intake control assembly for adjusting an air intake into a combustion chamber of a solid fuel burning appliance is provided. The air intake control assembly comprises a mounting structure having at least one air intake opening, a shutter mounted to the mounting structure and configurable between an open configuration and an at least partially closed configuration, a power supply, a motor operatively connected to the shutter and activable to modify a configuration of the shutter with respect to the at least one air intake opening, a temperature sensor electrically connected to the motor and the power supply to monitor a temperature representative of a temperature of the combustion chamber; and an electric circuit connecting the motor to the power supply and being operatively connected the temperature sensor. A solid fuel burning appliance and a method for controlling an air intake into a combustion chamber of a solid fuel burning appliance are also provided.

The present invention provides a hot water storage-type boiler having both a heat amount proportional control function and a backflow prevention function to prevent a backflow of exhaust gas with a simple structure. In the present invention, since a check valve is integrally coupled to a burner duct, there is an effect of convenient assembly. In addition, since the check valve is built in the burner duct, the check valve does not protrude to the outside, thereby having an effect that a separate space is not required.
