Flame Arresters which are devices which allows gas to pass

A flame arrester, the use of which in an open vent line or on the inlet to the Pressure/Vacuum Valve is an effective method to reduce the risk of flame transmission. The user is cautioned that the use of a flame arrester within the tank's relief path introduces the risk of tank damage from overpressure or vacuum due to plugging if the arrester

A typical cryogenic liquid cylinder is depicted below. This is an insulated, vacuum-jacketed, pressure vessel. They are equipped with pressure-relief valves and rupture disks to protect the cylinders from pressure build-up. Liquid containers operate at pressures up to 350 psig and have capacities between 80 and 450 liters of liquid.

HVAC Duct Construction Standards

Because total pressure is less downstream than upstream, a duct construction pressure classification equal to the fan outlet pressure (or to the fan total static pressure rating) cannot economically be imposed on the entire duct system. Pressure in ducts near room air terminals is nearly always below 1/2″ water gage (125 Pa).

Steam locomotive - Wikipedia

The intense heat causes water in the boiler to turn into steam, which is piped into the cylinders (24). Valves (25) cause the steam to oscillate the pistons (23) back and forth. The piston rod (22), connecting rod (21) and coupling rod (19) transmit the movement to bearings on the wheels, converting the oscillation to rotation, which moves the locomotive as shown in this animation

Safety valve - Wikipedia

A safety valve is a valve that acts as a fail-safe.An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would

Atomization - an overview | ScienceDirect Topics

P.R. Gogate, in Power Ultrasonics, 2015 30.1 Introduction. Liquid atomization is the process in which a liquid film coming out on a solid surface is subjected to a sufficient surface disturbance in the normal direction, such that the liquid gets separated from the surface or essentially splits into small droplets like a fog or mist in the gas phase. . Atomization of liquids is important in

Siphon - Wikipedia

A siphon (from Ancient Greek: σίφων, "pipe, tube", also spelled nonetymologically syphon) is any of a wide variety of devices that involve the flow of liquids through tubes.In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a reservoir, with no pump, but powered by the fall of the liquid as it
