The burner includes a first tube portion having a tube end including an ejection port and a second tube portion extending toward the ejection port in the first tube portion. The combustion gas generated by combusting air-fuel mixture is ejected from the ejection port. The second tube portion includes a heat exchanging portion that vaporizes liquid fuel with combustion heat of the combustion chamber and supplies the vaporized fuel to the premixing chamber. The outer surface of the second tube portion functions as a heat receiving surface of the heat exchanging portion. A fuel supply section of the burner is configured to vaporize liquid fuel and supply the vaporized fuel to the premixing chamber, and supply liquid fuel to the heat exchanging portion.

One embodiment relates to a burner, comprising a fuel pipe, a fuel nozzle, at least one ignition and/or heat source and a pipe which conducts an oxygen-containing gas and/or recirculated flue gas, wherein the at least one ignition and/or heat source is arranged in the burner interior and is in the form of or comprises an electric heating and/or ignition device via which, exclusively by conversion of electrical current into heat energy, the amount of heat energy required within the burner for the initiation and continuation of the initial pyrolysis and ignition is generated and/or provided in the burner interior. A stabilizing ring with toothed ring may be a constituent part of the electric heating and/or ignition device arranged in the mouth region of the fuel nozzle.

An air handling unit (AHU) for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing and a combustion heater disposed within the housing. The housing includes a combustion section with a first channel and a second channel. The combustion heater includes heat exchanger tubes and a tube support that supports heat exchanger tubes within the combustion section. The tube support slidably disposed in the first channel and the second channel. The combustion heater configured to be slidably removable from the AHU. An AHU for an HVACR system includes a housing with a fan section and a fan assembly disposed within the housing. The fan assembly including a pair of grooves slidably disposed on a pair of rails of the housing. The fan assembly configured to be both slidably removable from the AHU and liftably removable from the AHU.

A vaporization pipe for a kerosene lamp has an oil tube, a thermally conductive tube, and a first passage. The oil tube is made of steel and has a vaporization jet on a top of the oil tube. The thermally conductive tube is mounted in the oil tube and forms a first channel. The first passage is disposed between the oil tube and the thermally conductive tube. The steel oil tube can prevent the vaporization pipe from being softened and bent during the preheating of vaporization pipe or burning of the kerosene, and thus a useful lifetime of the vaporization pipe is prolonged. The thermally conductive tube is made of high-thermal-conductivity material for keeping the vaporization pipe with adequate thermal conductivity and improving a burning rate of kerosene. The first passage allows the kerosene to flow upward, preventing the kerosene from being vaporized incompletely because the kerosene is over pressurized.

Embodiments of integrated burner assemblies, for use in classified hazardous areas, effectively utilize a designated general or non-classified area classification inside a burner housing to simplify wiring connections between various components of a managed burner system. A valve train which supplies fuel to the burner and a control unit which manages the burner assembly and the valve train are mounted external to the burner housing in a classified hazardous area. Mechanically protected wiring is used to connect the valve train and control unit to the non-classified area. The open wiring connections inside the non-classified area, connecting between the burner assembly and the mechanically protected wiring from the control unit and the mechanically protected wiring from the valve train are free of mechanically protection considerations.

An apparatus and method for reclaiming uncondensed hydrocarbons normally exhausted to the atmosphere from a still column of a glycol dehydrator system, and combusting the uncondensed hydrocarbons in a burner assembly of a reboiler after the burner assembly has been ignited by fuel gas.

A smoke generator is provided, including a smoke generating unit and an airflow system. The airflow system has an air inlet passage, an air outlet passage and a vacuum generator, the vacuum generator communicates with the air inlet passage and the air outlet passage, and the vacuum generator has a suction portion communicating with the smoke generating unit.
