Types of motors and generators, gas CHP and CCHP and its difference with the diesel generator

Reciprocating engines, some sort of technology for distributed generation of electricity is considered to be the same سیستم of gasoline engines and گازوییلی vehicle design and are made . Builders of such engines دارای high volume production, and therefore the base price-per-kilowatt production of electricity by this technology, in the پایین the most competitive level, is located. This generating has the efficiency relative high of about 35 % to 45 % have been to for various applications, including courier, shaving, etc. working mode backup and permanent, and also the cogeneration of electricity and heat in small-scale, etc. are suitable. Reciprocating engines now have the installed capacity from a few kilowatts to about 5 MW, with the user providing electricity for permanent or backup system are. In these engines the ability to access close to a third of the fuel energy from the exhaust بادمای 370 degrees Celsius up to 540 degrees San تیگراد امکان feasible. But the other heat losses are so insignificant that can't be in often the process of recycling heat from the correct them benefit.

عملکرد همانطور that, as mentioned earlier., the reciprocating engines in the 4-stage act: (Intake) -1 log or مکشو :the friendliest of the air or air-fuel mixture into the cylinder. 2 - compression( Compression) in the engine compression, etc. of fuel near the end of the piston to cylinder injection can be. In engines, spark etc. the mixture of fuel and air, near the end of the piston محترق can be. : (Power Ignition) -3حرکت momentum the piston resulting from the pressure and the heat of the gases combustion combustion تخلیه cylinder and the exit of the product of combustion through exhaust (Exhaust) -4 drain :first, the incoming air and pressed them. then in the Chamber of the cylinder with the fuel composition can be, and with the movement of the piston., the combined fuel and compressed air can be . In diesel engines the air and fuel separate, enter the cylinder as a result. In these engines after compression, air in the cylinder by the piston, and. fuel into the cylinder, squirting can be. This compression by the piston takes place, causing the production of the Spark is this the spark causes the combustion to be. The pressure from the combustion causes the piston moves inside the cylinder can be applied, by the crankshaft connected to the piston., the released energy converts to mechanical energy can be. With the arrival of the piston to the end of the route, the drain valve open state, and operation, the drain cylinder is carried out. With the coupling of a generator to this motor can be the motor for the production of electrical energy benefit.

همانطور that in the pre-season or not. reciprocating engines as the cars can be divided into two categories اصلی division was: (Compression Ignition‐Diesel Cycle) • ignition systems compression (Spark Ignition‐Otto Cycle) • Ignition systems Spark

احتراق sanding This type of generating similar diesel engines was designed هاند and usually has توربوشارژر and coolants domestic بوده, with the efficiency of the electric 35% to 55 % in the range of 75 kW to 60 MW have been made. Fuel this type of generating, while the great heat of the compressed air resulting from the stage, hit the plunger, and the injection pressure of the fuel to a powder in the hot air, etc. Ignite can be and the mechanical energy to move the provides the formation . This type of combustion for a fuel such as natural gas are not suitable and to free up energy could be the system of ignition used. Engines, dual fuel, able to function combined with the two heavy fuel and natural gas You are. احتراق ...
