  An experimental study on pressure evolution during closed vessel explosions of propane-air mixtures was performed, for systems with various initial concentrations and pressures ([C(3)H(8)]= vol.%, p(0)= bar). The explosion pressures and explosion times were measured in a spherical vessel (Phi=10 cm), at various initial. THE CLASSIFICATION AND APPLICATIONS OF LIQUID LUBRICANTS Oils of both mineral and synthetic origin, mainly employed as lubricants but also used for other purposes, are termed liquid lubricants and are manufactured as such for commercial use.

of any substantial source of heat (including any boiler or furnace when alight) other than the burner. Approximately 12% of total acetylene production is used for welding and other high temperature combustion applications.

Acetylene production by partial oxidation of natural gas is undertaken mainly via the BASF process in a single stage premixed combustor, which operates with an oxygen:methane ratio ∼ (φ∼ ).

Medium Pressure TorchesThe medium pressure (usually called high pressure) torch (Figure 21) uses acetylene from a medium pressure generator or from tanks of compressed gas, but will not take the acetylene from low pressure generators.

The generation of acetylene for compression into dissolved acetylene cylinders is normally carried out in wet generators in which carbide is added to an excess of water.

Generator classification Operating Pressure Acetylene generators shall be designed, constructed and operated to standards and procedures, so as to ensure the maximum.

Buffers are installed in some types of medium pressure acetylene generators to balance the. generation rate to compression rate.

The buffer is a vessel with an integrated water seal - the function. of the water seal is as a safety device not a pressure relief. (If you’ve ever seen a blacksmith at work, you’ve seen hammer welding in action.) The next step was based on the discovery of acetylene in the middle of the 19th century.

05_chindd _chindd 11 Controlled use of acetylene gas (combined with oxygen) allowed people to cut and melt metals in a way that wasn’t possible. The explosions cause great heat, so some system of cooling the cylinders either by air or water must be used.

Only one cylinder has been explained here, but most engines have several, each working at a different stage, so that the power is exerted on the shaft continuously. Lubricating oil is supplied to a low- and a medium-pressure system. The low-pressure system supplies the main and other bearings.

The crosshead bearing, reversing servo motors and exhaust valve actuators are supplied by the medium-pressure system. Cylinder oil is supplied to lubricators from a high-level service tank.

Avoidance of Explosions through Inerting The introduction of inert gas in the area to be protected against explosions lowers the oxy- gen volume content below the limiting oxygen concentration (LOC) so that ignition of the mixture can no longer take place.
