Compressed Air Technologies
All Wartsila Power Plant needs compressed air the process-compressed air technologies systems are divided into two different systems: Read about Diesel Air Compressor
- Starting Air System
- Used for starting of the engine
- Back up control air
- Pressure 30 bar
- Control Air System(also called Instrument Air)
- Used by pneumatically controlled components in the power plant
- Pressure 7 bar
- Used as working air for tools etc.
The specifications of Starting Air Compressor of JPP are following:
Rated Power…………………………..11 KW
Rated Voltage…………………………380/415 V
Rated Current………………………….22.2/20.5 A
Power Factor…………………………..90.1
No. of phase……………………………Three
compressed air technologies by 3-compressor then it is passed through a cooler. The compressed air from cooler is stored in air vessel. The Distributor supplies the starting air to cylinder as firing order.
The starting air unit has an outlet line with a pressure reducer, connected to the instrument air system. This enables the starting air unit compressor. The instrument air unit supplies air at lower pressure to pneumatically operated devices on the engine and in the auxiliary system.
The specifications of Instrument compressed air technologies of JPP are following:
Model…………………………………..UP52210 Rotary
Serial No………………………………..32054
Capacity…………………………………3.11 m3/min
Rated Pressure……………………………1.0 MPa
Rated power………………………………22 KW
Following specification is for Air dryer:
Model…………………………D3001N
Rated Air Flow………………5000 L/min
Rated Power………………….1.43 KW
Rated Pressure………………..14 Bar
Maximum Temperature……….60 C
Charge Air
- The main function of the charge air system is to provide the engine with clean and dry combustion air of sufficient quantity and quality.
- The combustion air (charge air) to the engine is drawn from outside the building (open air).
- The air is drawn through the air intake filtration unit via a pipe system provided with a charge air silencer into the turbochargers installed to the engine. The compressed charge air is cooled in the charge air coolers before it enters the engine’s charge air receiver.
Exhaust System The exhaust gas system leads the exhaust gases to turbocharger and after that out of the power house, thus ensuring that emissions and noise are kept on an acceptable level. The exhaust gas system consists of pipes, flexible bellows to compensate for thermal expansion, and an exhaust gas silencer. The exhaust gas system is equipped with a ventilation unit and explosion vents located at strategic places
Ignition System of compressed air technologies
- Ignition is initiated by a spark plug.
- The control system determines the timing of the spark.
The high voltage (20-25 KV) link between the ignition coil and the spark plug.
