There are provided a cement kiln burner device capable of intensively bringing a combustible solid waste into a floating state within a cement kiln and easily causing ignition of the combustible solid waste in the floating state, and a method for operating the same. According to the present invention, there are provided: a powdered-solid-fuel flow channel including means for swirling a powdered-solid-fuel flow; a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel, the first air flow channel including means for swirling an air flow; a second air flow channel placed in an outermost side outside the powdered-solid-fuel flow channel, the second air flow channel including means for straightly forwarding an air flow; and a combustible-solid-waste flow channel placed inside the first air flow channel. The second air flow channel is divided in a circumferential direction into four or more opening portions adapted to form ports for injecting air flows, and is configured to control flow rates of the air flows ejected from the opening portions, independently for each opening portion.

A heat shrink gas gun has a handle which has a back side and a front side. The front side of the handle includes a cavity extending along an axis. An igniter is configured for ignition of the heat shrink gas gun and is actuated by a trigger. The igniter is insertably disposed in the cavity. The igniter is releasably received in the cavity. A trigger guard is positioned in front of the trigger and the front side in a spaced relationship. The trigger guard includes a through hole corresponding to the cavity so as to facilitate installation and replacement of the igniter.

Various disclosed embodiments include combined heating and power modules and combined heat and power devices. In an illustrative embodiment, a combined heat and power device includes a heating system including: at least one burner; at least one igniter configured to ignite the at least one burner; a fluid motivator assembly including an electrically powered prime mover; and a heat exchanger fluidly couplable to the fluid motivator assembly. At least one thermophotovoltaic converter has a photon emitter and at least one photovoltaic cell, the photon emitter being thermally couplable to the at least one burner, the at least one photovoltaic cell being thermally couplable to the heat exchanger.

Methods and systems for oxidizing gas are provided. An example regenerative oxidizer is provided that includes a combustion chamber to heat gas present in the combustion chamber. The regenerative oxidizer also includes a first heat exchange media bed and a second heat exchange media bed. Each of the first heat exchange media bed and the second heat exchange media bed are in fluid communication with the combustion chamber. The regenerative oxidizer further includes two burners disposed within the combustion chamber to provide a total heat input to the gas present in the combustion chamber. At least one of the two burners is independently adjustable based on the airflow direction.

A method of melting a charge in a double-pass tilt rotary furnace having a door, including operating a first burner at a first firing rate, the first burner being mounted in a lower portion of the door and producing a first flame having a length; operating a second burner at a second firing rate, the second burner being mounted in an upper portion of the door and producing a second flame having a length, the second flame being distal from the charge relative to the first flame; in an initial phase when the solids in the charge impede the first flame, controlling the second firing rate to be greater than the first firing rate; and in an later phase after melting of the solids in the charge sufficiently that the first flame is not impeded, controlling the first firing rate to be greater than the second firing rate.

A method and apparatus for combustion of fuel in a combustion chamber with a hydraulic diameter D. Fuel and a primary oxidant are introduced via a burner lance into the combustion chamber, having a certain mean velocity u1 at entry, and a secondary oxidant with a mean velocity of u2 is introduced into the combustion chamber. The burner lance has a position p that has a distance Id1I defined as the smallest distance between p and a combustion chamber centerline a

The present disclosure relates to a system and a method for combustion of solid fuels. The combustion system includes burners which supply a mixed flow of fuel and air through a fuel nozzle to the combustion chamber for example of a boiler. The mixed flow of fuel and primary air is supplied to the burner through a duct from a pulverizer where the fuel is grinded to the required finesse. The duct further bends in such a way that one portion is vertical with respect parallel to axis of the boiler 1 A-A is vertical duct and other portion is horizontal duct which is parallel to axis B-B of the fuel nozzle.

Provided is a cooking device. The cooking device includes a frame to form a cooking chamber; a burner to heat the cooking chamber; a gas valve to control a flow of a gas which will be supplied to the burner; an ignition unit to ignite a mixed gas of the gas and air which is supplied to the burner; a fan to enable the air heated by the burner to flow; a fan motor to rotate the fan; and a control unit to control the fan motor, wherein, when the fan motor is normally operated, the control unit turns on the gas valve and operates the ignition unit.
