industrial gas turbines range from microturbines to much larger designs. often, microturbines are rated below 40 kw, and have an installed cost of nearly $1,000/kw and provide an efficiency around 15–20%. by comparison, large gas turbines (rated above 25 mw) typically cost around $300–400/kw and have an efficiency above 35%.
the water screw, popularly known as the archimedes' screw and also known as the screw pump, archimedean screw, or egyptian screw, is a machine used for transferring water from a low-lying body of water into irrigation ditch water is pumped by turning a screw-shaped surface inside a pipe. fundamentals of design
increasing fuel cost 50% from the base value fim 45/mwh (usd 2.3/gj) improves the competitiveness of new concepts, but the rankine is continuously more economic over the whole annual operation time.
special hazards are important because we need to protect extremely valuable assets. if one wind turbine goes up in flames, the average cost to build a new one is $4m! 4. even worse, some assets are irreplaceable in regards to monetary value. think expensive
installation of a separate vent line for the degasser unit to its own flare stack revealed that nearly all the vent gas produced at the battery was being recpvered in the degasser. this information made any vapor recovery project for the salt creek field more attractive because of the larger-than-expected recovera~le gas flow rates. this degasser design has proved to be a very efficient separator in terms of liquid and gas capacity for a very reasonable cost.
as an example, lead dust, which is relatively heavy, typically requires a minimum conveying velocity of 4,500 feet per minute, whereas weld fume, which is much lighter, may require 2,000 – 2,500 feet per minute. when conveying velocities are not sufficient to keep the material moving through the duct, the potential exists for the dust to dropout and settle in the duct.
for larger steam turbines (as per api 612) labyrinth seal is used as shaft seals. in the case of condensing steam turbine to prevent the air ingression at the shaft seal by gland condenser and ejector arrangements(as per api 612). blade seals. blade seals are used to prevent the steam leakage between the diaphragm and the shaft.
the turbo-jet engine is a modified form of gas turbine engine. a turbo-jet consists of a diffuser, rotary compressor combustion chamber, turbine and nozzle. working. air from the surrounding atmosphere is drawn by the compressor through the diffuser slows down the entering the speed of the air and compresses it. this is known as ram compression.
