A fuel connection unit (10) for a fuel-operated vehicle heater (18) includes a connection unit body (12), which can be arranged at a heater housing (16). A fuel release line connection area (32) connects a fuel release line leading to a combustion chamber. A fuel feed line connection area (46) projects from the connection unit body (12) for connecting a fuel feed line. At least one functional unit (50), for influencing the flow of fuel in a fuel flow volume (36) formed in the connection unit body (12), is provided in the connection unit body (12).

A gas distribution assembly that includes a valve mounted on a distribution duct. According to one implementation the body of the valve is supported on the duct by support having a base and a plurality of arms extending from the base. The arms have surfaces that rests on projections of the valve body. A fixation device is furthered used to secure the support to the valve body. The support is configured to hold the valve body on the duct in the event the fixation device fails to secure the support to the valve body.

A fuel connection unit for a fuel-operated vehicle heater includes a connection unit body (12) to be mounted on a heater body (78). A fuel release line connection area (16) is positioned such that it meshes with or faces an interior (80) of the heater body (78). The fuel release line connection area (16) connects a fuel release line (104), extending in the interior (80), with a fuel feed line connection area (20) to be positioned exposed on an outer side of the heater body (78), for connecting a fuel feed line.

Magnetic treatment of hydrocarbon fuel flowing through a fuel conduit. A plurality of magnets with repelling polarity affects the fuel structure and alternating said structure by aligning the hydrocarbons in a parallel uniform manner to increase combustion efficiency, thus increasing power while reducing pollutants and exhaust emissions.

A circuit (10) for draining at least one combustible fluid for a cavity of a turbine includes a drain (12) in fluidic communication with the at least one cavity, and a first isolation valve (14) and a second isolation valve (16) defining between them an isolation cavity (C) of a portion of the drain. A discharge line (18) is in fluidic communication with the isolation cavity (C) to allow the discharge of air out of the isolation cavity (C). A supply line (22) supplies pressurized fluid to the isolation cavity (C), and a supply valve (24) is arranged in the supply line (22) for regulating the supply of the isolation cavity (C) with pressurized fluid. A discharge valve (20) is arranged in the discharge line (18) for regulating the discharge of the gases out of the isolation cavity (C), and—a device (26) is provided for determining a failure of the drainage circuit (10).

A quick-disconnect gas pipeline comprises a quick-disconnect device (QDD) which comprises a QDD male end and a QDD female end, and a gas hose. The QDD male end is connected to the gas pipeline inside the heating system and the QDD female end is connected to the gas hose outside the heating system. When the heating system is not used, it is easy to disconnect the QDD to prevent people from tripping over the long gas pipeline.

A system and method for recycling flare gas back to a processing facility that selectively employs different numbers of ejector legs depending on the flare gas flowrate. The ejector legs include ejectors piped in parallel, each ejector has a flare gas inlet and a motive fluid inlet. Valves are disposed in piping upstream of the flare gas and motive fluid inlets on the ejectors, and that are selectively opened or closed to allow flow through the ejectors. The flowrate of the flare gas is monitored and distributed to a controller, which is programmed to calculate the required number of ejector legs to accommodate the amount of flare gas. The controller is also programmed to direct signals to actuators attached to the valves, which open or close the valves to change the capacity of the ejector legs so they can handle changing flowrates of the flare gas.

Dampers and a fuel delivery systems including such dampers are disclosed. The damper includes a first component and a dampening component. The first component is coupled to a first tubular element and includes a first extended hollow section. The dampening component is coupled to a second tubular element. The dampening component includes a first end portion including a plurality of slits. The first end portion is disposed within the first extended hollow section to frictionally couple the first end portion to the first extended hollow section.

The invention relates to a burner assembly (100) comprising at least two gas supply lines (1, 2) for supplying at least two different gases, a gas mixture supply line assembly (11), in which the mixture of the at least two different gases is passed on and fed to at least one burner head (20) in which the mixture is combusted, wherein the gas mixture supply line assembly (11) and/or at least one of the gas supply lines has at least one flexible metal tube (1, 2, 13, 16, 19, 21).

A quick-disconnect gas pipeline comprises a quick-disconnect device (QDD) which comprises a QDD male end and a QDD female end, and a gas hose. The QDD male end is connected to the gas pipeline inside the heating system and the QDD female end is connected to the gas hose outside the heating system. When the heating system is not used, it is easy to disconnect the QDD to prevent people from tripping over the long gas pipeline.
