A burner assembly including a body, the body including a first aperture, a second aperture, a cavity between the first and second aperture, and a gas inlet in fluid communication with the cavity. The assembly also includes a gas nozzle arranged to terminate a first distance from the first aperture of the body. The assembly also includes a fuel tube and a fuel nozzle disposed within the cavity of the body, the fuel tube arranged to terminate within a first through-bore of the gas nozzle, and the fuel nozzle being removably secured to the fuel tube, the fuel nozzle terminating a second distance from the first aperture of the body, wherein the first distance is less than the second distance or the first distance is substantially equal to the second distance.

A cutting nozzle assembly and associated method of making same includes a nozzle having a central bore extending therethrough along a longitudinal axis through which an associated cutting gas is discharged. A plurality of spaced fuel gas bores are arranged around the central bore, and preheat passages are arranged around both the central bore and the fuel gas bores. A retaining nut receives at least a portion of the nozzle therein, and the retaining nut includes a shroud extending axially outward from a discharge end of the nozzle. At least one of an inner surface of the shroud and the additional preheat passages are angled inwardly toward the longitudinal axis. The fuel gas bores and the preheat passages each have the same cross-sectional dimension, and twice the number of preheat passages as fuel gas bores are provided.

A detoxification device has an inlet nozzle capable of reducing an amount of a deposit of an adhering metallic product and elongating a maintenance cycle and a detoxification device including the inlet nozzle. The inlet nozzle includes a portion adjacent to a combustor, that is cut (removed) in advance. Consequently, in the portion, an insulator made of a ceramic material is exposed. Since the ceramic material supplies a small number of electrons, even when the insulator is exposed to heat from the combustor to reach a high temperature, a reductive reaction is less likely to occur. Accordingly, even when a metallic exhaust gas is allowed to flow, the metallic exhaust gas is prevented from being precipitated as the metallic product and gradually deposited with time.

A spacer for a fluid nozzle can include a body configured to fit within a sheath of the fluid nozzle such that a fluid tube positioned within the sheath is held bent over its longitudinal dimension by the body thereby altering a natural frequency of the fuel tube compared to if the fuel tube were not held bent.

A gas manifold allows each distribution chamber to be fed with fuel gas at an appropriate flow rate irrespective of an increase in the number of distribution chambers included in the gas manifold. Fuel gas flowing through in an inlet is distributed to a plurality of distribution chambers through a main channel. A bypass channel parallel with the main channel also feeds fuel gas to a maximum distribution chamber. This can prevent the feeding of the fuel gas to the maximum distribution chamber from being affected by and reduced by the feeding of the fuel gas to the bypassed distribution chambers. This also prevent the feeding of the fuel gas to the other distribution chambers from being affected by and reduced by the feeding of the fuel gas to the maximum distribution chamber. The plurality of distribution chambers are thus fed with fuel gas at appropriate flow rates.
