A burner comprising least one first passage and at least one second passage are formed in the burner, the at least one first passage and the at least one second passage are arranged such that a first fluid from an outlet of the at least one first passage and a second fluid from an outlet of the at least one second passage are mixed with each other, and the at least one first passage is configured to cause the first fluid to produce a rotational flow in a first rotation direction, and/or, the at least one second passage is configured to cause the second fluid to produce a rotational flow in a second rotation direction.

A method and device heat an object to be heated by a flame which is produced by supplying a fuel fluid and a combustion supporting gas to a burner as a heat, source. A temperature rising rate is increased by gradually increasing an oxygen concentration in the combustion supporting gas supplied to the burner and a device for heating an object to be heated including a burner for heating the object to be heated. A flow rate control unit controls a flow rate of a fuel fluid and a combustion supporting gas. A calculation unit transmits combustion information of the burner to the flow rate control unit, and the flow rate control unit increases a temperature rising rate of the object to be heated by increasing the oxygen concentration in the combustion supporting gas supplied to the burner.

A powder coated aluminum barbecue pit burner that burns gas in the same way that stainless steel burner tubes do, but last longer and do not rust. The use of powder coated aluminum makes the burner according to the present invention corrosion resistant. Additionally, the powder coated aluminum burner of the present invention also contain a heat sink element that prevents the temperature of the tubes from getting too high. Controlling temperature and using powder coated aluminum burners, instead of stainless steel, ensures that the burner will last longer. Another embodiment utilizes a water cooled system in connection with the heat sink element.

A burner characterized by being equipped with: a fuel supply nozzle to which a mixed flow of a solid fuel and a solid fuel transport gas is supplied; a flow passage that is arranged on the outside of the fuel supply nozzle and that supplies combustion air separated from the mixed flow; and ammonia supply nozzles which are capable of supplying ammonia on the downstream side of the outlet of the fuel supply nozzle toward a reduction region in which oxygen in the transport gas has been consumed due to ignition of the fuel and the progress of combustion, resulting in a low oxygen concentration. Thus, it is possible to provide a burner capable of burning a mixture of a solid fuel and ammonia, and a combustion device equipped with this burner.

An example Smart Candle Platform is configured to includes a candle fixture that comprises an outer shell having an opening, a mid-frame, and a base, and a fuel bottle configured to hold a fuel material and is removably coupled to the candle fixture. The fuel bottle is positioned at least partially within a hollow interior of the mid-frame of the candle fixture and accommodated by the base. The fuel bottle further comprises a wick that extends through an opening of the outer shell, and the candle fixture includes an ignitor configured to ignite the fuel material via the wick to produce a living flame. The candle fixture further includes an inner cover having one or more reinforcement ribs configured to provide structural support for the one or more ignitors.

A burner comprises a central passageway and outlets for fuel and for stabilizing oxidant arranged peripherally around the central passageway, and comprises outlets within the burner through which biasing gas, such as gas comprising oxygen, can be injected to enable control of the direction of the flame that is generated by combustion of the fuel and the oxidant at the face of the burner.

An atomizing burner and corresponding method for turning an atomizing burner from an ON state to an OFF state. The burner has independently controllable flows of atomizing air, combustion air, and fuel flow, the burner in the ON state having flow values of burner parameters including flow of atomizing air, flow of combustion air, and fuel flow. The method includes: changing, in response to an OFF instruction, flow of at least one of the flow of atomizing air, combustion air and/or fuel to a lower non-zero value; first discontinuing, after a first period of time since the changing, flow of fuel and flow of atomizing air; maintaining, for a second period of time since the first period of time, flow of combustion air; second discontinuing, after the maintaining, flow of combustion air; wherein the maintaining prevents buildup of excess heat inside the burner during the transition to the OFF state.
