Pellet grills including a control system that implements, manages, and/or controls various ignition-based protocols are disclosed. An example pellet grill includes a cooking chamber, a burn pot, an ignitor, and a controller. The ignitor extends into the burn pot and is configured to ignite pellet fuel located within the burn pot. The controller is configured to detect a temperature pattern of the cooking chamber corresponding to a flame out condition of the burn pot. The controller is further configured, in response to detecting the temperature pattern, to command the ignitor to activate during a first duration. The controller is further configured to determine, following expiration of the first duration, whether a temperature of the cooking chamber increased during the first duration. The controller is further configured, in response to determining that the temperature has not increased during the first duration, to command the ignitor to activate during a second duration.

A grilling device includes an auger feeder system, a heating element, a blower and a temperature control system. The temperature control system includes at least a first temperature sensor inside the firepot and a second temperature sensor inside a cooking chamber above the firepot. The heating element can also serve as the first temperature sensor. A method for controlling the temperature of the grill can include receiving temperature feedback information from one or more of the temperature sensors and adjusting power provided to the auger feeder system, heating element, and blower. The temperature control system produces cold smoke resulting from the combustion of lignin in solid wood fuel while minimizing temperatures inside the cooking chamber.

A portable grill with a battery power system includes a primary direct-current power source and a secondary direct-current power source. The primary power source can connect onto the outside of the grill via a clip. The secondary power source, which can be disposed within the grill so as not to be exposed to outside elements, can continue to power the grill when the user removes and/or replaces the primary power source during the operation of the grill. A user feedback system can remotely alert the user with information regarding the time or power remaining in the primary power source.

Systems and methods for automatically igniting fuel within a fuel source hopper of a grill are disclosed. In one form, a fire starter tray of a fuel source hopper is positioned beneath a stack of fuel, wherein when a starter block of the fire starter tray is ignited, the starter block ignites the stack of fuel. A heating element of the fuel source hopper is configured to ignite the starter block and a fan of the fuel source hopper is configured to provide an airflow to an area beneath the stack of fuel where the starter block ignites the stack of fuel. A controller in communication with display and user controls and the heating element and the fan is configured to operate the heating element and the fan to automatically ignite the stack of fuel based on information received from the user via the display and user controls.

The present disclosure relates to a solid-fuel cooker, such as a barbecue, comprising: a body defining a chamber configured to act as a firebox for combustion of solid fuel, such as charcoal or briquettes; a fuel support structure for supporting the solid fuel in the chamber; and an ignition system for igniting the solid fuel supported by the support structure. The ignition system comprises at least one electric heating element mounted to the body and located in or adjacent to the chamber for heating the solid fuel supported by the support structure, the at least one electric heating element configured to be switched between an electrically energized (i.e. switched on) state and an electrically de-energized (i.e., switched off) state. The at least one electric heating element is configured to transfer heat to the solid fuel supported by the support structure to ignite the solid fuel when the switch is operated to the electrically energized (i.e. switched on) state.

The invention relates to a pulverized coal burner for a steam generator. The pulverized coal burner has a fuel duct, through which pulverized coal is conveyed with the aid of a carrier gas. The pulverized coal emerges together with the carrier gas at a fuel duct outlet. The pulverized coal burner furthermore has at least one core duct and at least one secondary duct. Air or oxygen flows through the core duct and the secondary duct, emerging at the core duct outlet and at the secondary duct outlet. The core duct outlet, the secondary duct outlet and the fuel duct outlet together form a burner outlet. The pulverized coal burner has at least one plasma ignition torch embodied integrally with the pulverized coal burner. The outlet of the at least one plasma ignition torch is arranged in the plane of the burner outlet or offset downstream in relation to the direction of flow of the pulverized coal. The plasma flame produced by the plasma ignition torch is thus located outside the fuel duct.
