A furnace, and a method of firing it, wherein part of the fuel supplied to the furnace is produced from waste plastics by a depolymerisation process, waste heat from the furnace being used to promote the depolymerisation process. The furnace is equipped with regenerators for waste heat recovery and is fired alternately in first and second opposed directions, with the direction of firing periodically reversing between the first direction and the second direction. The supply of fuel to the furnace is temporarily interrupted while the direction of firing is reversing, means being provided to accommodate the fuel produced during the temporary interruption. The furnace may be used for producing glass.

An infrared radiator for the heat treatment of a material web has an incandescent body with a flow-receiving surface that is subjected to a flow of a gas-air mixture supplied to the infrared radiator and heated by combustion of the gas-air mixture. The incandescent body is manufactured as a sheet material formed of a multiplicity of threads and connecting elements that at least indirectly connect the threads to one another. The connecting elements at least partially engage around the threads and thus connect them at least indirectly to one another. The connecting elements are configured in such a way that they may be detached from the connection with the threads, preferably by hand, while breaking up the sheet material.

A burner for producing synthesis gas by partial oxidation of liquid or gaseous, carbon-containing fuels in the presence of an oxygen-containing oxidant and a moderator, which burner can be operated uncooled, i.e. without a fluid coolant being passed through the burner, is proposed. Steam or carbon dioxide or else mixtures of these materials are used as moderator. This is achieved by the feed channels being configured so that mixing of the fuel, the moderator and the oxidant occurs only outside the burner.

A pilot and burner apparatus is provided for use in firefighting training. The apparatus includes a main fuel conduit and a main fuel valve. The apparatus includes a pilot tube and a pilot fuel conduit configured to deliver fuel from the main fuel conduit to the pilot tube. The apparatus includes main and pilot fuel valves to respectively control a flow of fuel in the main and pilot fuel conduits. In a pilot phase, the valves direct fuel to the pilot tube. An ignition component is configured to ignite fuel in the pilot tube to generate a pilot flame. In a burn phase, the pilot flame generates a controllable flame out of a main burner pipe by igniting fuel exiting the main fuel conduit. The controllable flame can be delivered to a training structure for training purposes.

Embodiments of the present disclosure describe burner (10) configurations used in an industrial process to convert methane to olefins, aromatics, and nanoparticles/nanomaterials. Both a vitiated coflow burner and piloted turbulent burner with inhomogeneous inlets are disclosed.

A gas flare apparatus includes a burner tube that receives combustible gas and includes (a) a burner tube outer perimeter defined by a burner tube outer diameter and (b) a burner tube inner perimeter defined by a burner tube inner diameter. An updraft shield is concentric with the burner tube and extends outwardly relative to the burner tube outer perimeter to an updraft shield outer perimeter. A windshield tube is concentric with the burner tube and has a windshield tube inner diameter that is larger than the burner tube outer diameter. The windshield tube is positioned above the updraft shield. A cover plate spaced apart from and covering an upper opening of the windshield tube.

An ironing apparatus (100) comprises a rotating cylinder (11) and a burner assembly (2) comprising a main body (20) in which a passage (21) for a mixture of air and gas is defined. The main body comprises an outlet surface (22) in which a plurality of holes (220) are defined, through which the mixture of air and gas exits from the passage, wherein the passage is elongate-shaped, extends in a longitudinal direction inside said rotating cylinder and has a decreasing cross section along the longitudinal direction (x).

Systems and methods for a fire device forming at least one stream of flames within a center housing, and directing the at least one stream of flames through one or more apertures formed into an upper surface of the center housing and vertically above the center housing. In some examples, one or more gaseous fuel streams are injected towards the at least one stream of flames and above the center housing via fuel injection ports positioned outside of the center housing.

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.
