Horizontal cylinders

The large, heavy-duty, integral engine-compressor has long been the workhorse of the gas compression industry. The in-line or V-shaped power cylinder, horizontal compressor cylinder configuration is lamitiar. 

Figure 14-4A. Oscillogram shows variation of current to a synchronous motor driving a reciprocating compressor, The compressor is two-cylinder, horizontal, double-acting, and operates at 257 rpm. Line A is the envelope of the current wave. Difference B-C is current variation. Value B-C divided by the rated full load current is the percentage of current variation.

New situations arise with the cylinder horizontal in the interface. Two alternatives present themselves. 

Deep hand-dug pits are used to collect clean samples down to a depth of 10-15 m. Using appropriate clean-room clothing and ultra-clean shovels and tools (28), operators may dig pits and collect various sized blocks (28, 29) or several samples by pushing ultra-clean plastic cylinders horizontally into the walls, from the surface to the bottom of the pit (27, 30). 

Apart from the rotary engines described above, piston engines can all be classified as radial or in-line. In-line engines may have either one bank of cylinders, horizontal or vertical, or they may have two or more banks in various arrangements, Fig. 11.2. 

So far, for computation of heat transfer from vertical flat plates and cylinders, horizontal cylinders and spheres, we have used Table 6.4 correlations in the form of... 

No. Section 1926.350(a)(9) provides Compressed gas cylinders shall be secured in an upright position at all times except, if necessary, for short periods of time while cylinders are actually being hoisted or carried. Section 1926.350(a)(9) clearly provides that compressed gas cylinders must be stored in an upright position when they are not being hoisted or carried. Therefore, storing cylinders horizontally is not permissible under the standard. 

Now place 35 ml. of the mixed solvent (C) in the clean cylinder E, and suspend the strip, as described above, to the horizontal arm of G (Fig. 25(A)) adjust the position of the strip so that, when the bung is firmly in position, the bottom of the paper-strip is about 5 mm. above the solvent. Place the cylinder for 5-8 hours in a draught-free place, such as a cupboard, where the temperature is reasonably constant. 

The Bucher-Guyer horizontal rotary press is a highly automated batch process machine that requires no press aid. The press consists of a horizontal hydrauhc ram inside a rotating cylinder containing many flexible rods covered with a knitted synthetic fabric. The rods have serrated surfaces to allow juice which passes through the fabric to flow to the discharge ends. Hydrauhc pressure is apphed for a preset time, the ram is retracted, and the cylinder is rotated to break up the press cake. This cycle is repeated several times before the press cake is removed from the cylinder and the press is cleaned (16). Juice yield for this horizontal rotary press is 84% with secondary water addition it is increased to 92% (15). 

For distributing larger quantities of gaseous helium, argon, and occasionally neon, a number of large, horizontal, compressed gas cylinders are manifolded on tmck semitrailers (called tube trailers) or railroad cars. Like individual cylinders, these serve both as transport containers and rental storage containers. Capacities of tube trailers range from about 300 to 5,000 m (10,000—175,000 fT) of gas. 

The first of these reactions takes place at temperatures of about 150°C, the second reaction proceeds at about 550—660°C. Typical furnaces used to carry out the reaction include cast-iron retorts the Mannheim mechanical furnace, which consists of an enclosed stationary circular muffle having a concave bottom pan and a domed cover and the Laury furnace, which employs a horizontal two-chambered rotating cylinder for the reaction vessel. The most recent design is the Cannon fluid-bed reactor in which the sulfuric acid vapor is injected with the combustion gases into a fluidized bed of salts. The Mannaheim furnace has also been used with potassium chloride as the feed. 

The entire QSL process takes place in a single reactor as shown in Figure 6 (15). The reactor consists of an almost horizontal, refractory-lined cylinder, which can be tilted by 90° when operation is intermpted. Concentrates, fluxes, recirculated flue dust, and normally a small amount of coal, depending on the type of concentrate, are pelletized. The pelletizer ensures that the raw materials are mixed to the required degree of uniformity. 

In nonmetaUic vessels, the second plate of the capacitor is missing and must be suppHed. A stiUweU probe, one with a concentric metal tube, is utilized. The concentric tube suppHes the second plate. StiUweU probes have numerous other uses. In appHcations of nonconductive media, a stiUweU probe is more sensitive and suppHes a greater amount of capacitance because the ground reference is so close to the probe. Further, if a tank waU offers a ground reference that is a varyiag distance to the probe, eg, a horizontal cylinder, the stiUweU offers a much more consistent (linear) ground reference. 

The three most common diffuser configurations are a vertical cylinder in which the semifluidized cossettes ate scrolled upward (tower), a pair of upward-moving inclined twin-screw scrolls with cascading juices (slope), and a horizontal rotating dmm equipped with offset compartments which allow the cossettes to fall forward as the dmm turns (Raffinetie Tirlemontoise (RT) horizontal). Residence time within all of these diffusers is typically 45 to 60 minutes. 

A calcining kiln is a horizontal steel cylinder, slightly sloped to help the coke move forward and lined with refractory brick. The raw coke is fed at the upper end, natural gas or oil is burned at the lower end, and the combustion gas flows through the kiln above and against the coke stream.
