The present disclosure describes an assembly configured to mitigate the harmful effects of smelt fouling, airflow interference, and operator exposure to hot air from the furnace and wind box through use of an extractable startup burner and an isolation chamber engaged to a windbox. The present disclosure also describes a method for safely extracting a startup burner from an active recovery boiler as has method for inserting an extractable startup burner into a recovery boiler during operation.

A gas-fired burner for a drying drum of an asphalt mixing plant, such that the burner preferably has a central primary air duct (6), which opens into a combustion zone (4) via a swirl body (2). The burner has gas supply openings (9) in the area of the circumferential boundaries of the swirl body (2) for supplying fuel gas to the primary air for firing the burner. It has been shown that a stable and well-developed flame can be produced over a very large load range with such burners according to the disclosure.

A well test burner system includes a plurality of burner nozzles, each including an air valve and a well product valve movable between an open position, where air and a well product are allowed to circulate through the burner nozzle to discharge an air/well product mixture, and a closed position, where the air and the well product are prevented from circulating through the burner nozzle. One or more actuation devices are operatively coupled to the air valve and the well product valve to move the air valve and the well product valve between the open and closed positions.

The handheld snow melter is a handheld propane or stabilized methylacetylene-propadiene fueled parabolic heated intended for use in removing snow and ice. The handheld propane or stabilized methylacetylene-propadiene torch is used to heat a ceramic cone. The ceramic cone is mounted in a parabolic reflector that is used to direct the heat towards the snow or ice targeted by the user. The handheld snow meiter comprises a reflector, a torch attachment, and a grip.

Burner for a reforming reactor including an oxidizer pipe arranged coaxially within a process gas annular channel, wherein the nozzle has a trumpet-like shape and the lip of the nozzle has a wave or sinusoidal profile.

A distribution ring for fuel in a burner (7) includes a hollow body (21) which is configured to be annular with respect to a longitudinal axis (22), a feed spigot (23) which is connected to the hollow body (21) and is intended for feeding the fuel into the hollow body (21), and a plurality of discharge spigots (25) for discharging the fuel from the hollow body (21) to the burner (7). The discharge spigots (25) are each arranged externally at the hollow body (21) in the radial direction of the longitudinal axis (22).
