Devices and methods for outdoor heating. A stove device includes a fuel system attached to a combustion chamber to deliver fuel from a hopper of the fuel system to the combustion chamber for combustion in a firepot assembly positioned inside the combustion chamber. A distance between a chute of the fuel system and the firepot assembly is adjustable to change an amount of fuel for combustion and thereby control temperature of combustion. The distance may be decreased to decrease the temperature and may be increased to increase the temperature

Cooking apparatus for cooking food by a barbecue grilling method, comprises an outer housing receiving an inner housing which defines a heating volume. A chamber for pressurised air is defined between the outer and inner housings. Apertures in the inner housing allow pressurised air to exit the chamber into the heating volume. At least one burner is located in the inner housing. A combustible fuel/air mixture is supplied to the burner and this is separate from the supply of pressurised air to the chamber. A cooking surface is placed across the top of the heating volume to support food to be cooked.

The objective of the present invention is to provide a combustion device capable of informing an amount of used gas, in which an air of gas temperature is reflected, to a user and a method of measuring the amount of used gas. To this end, the combustion device includes: a burner configured to burn gas; a blower configured to supply air for combustion to the burner; gas valves configured to supply gas for combustion to the burner; a gas temperature sensor configured to measure a temperature of gas supplied to the burner or the blower; and a control unit configured to control the number of revolutions of the blower, calculate a first amount of used gas for a present operating heat quantity burned according to a signal input by a user, and compensate the calculated first amount of used gas with a measured gas temperature measured by the gas temperature sensor to calculate a second amount of used gas.

A gas burner assembly for a cooktop appliance includes a normally aspirated primary burner and a concentrically-positioned forced air boost burner. A dual-outlet control valve provides a flow of primary fuel to the primary burner through a first outlet and a flow of boost fuel to the boost burner through a second outlet. The boost burner operates by receiving the flow of boost fuel and a flow of combustion air from a forced air supply source only when the primary burner is operating in a low condition.
