The Siersza Power Plant in Trzebinia is a part of The Southern Power Concern S.A. Katowice since 2000. It is situated in the north-western part of the Malopolska Voivodeship in the Trzebinia administrative territory and was constructed between 1962-1970 as a system power plant.
The compressor system
When the attitude to waste management changed to reduce its harmful impact on the environment, the way it is transported also had to be changed. Waste hydrotransport was exchanged for pneumatic transport in 1994. It was connected with the neccessity to install highly efficient and reliable compressors which can meet the requirements. Currently in the Siersza power plant there is a main compressor system which satisfies all the basic needs concerning the plant's demand on the compressed air. Three turbocompressors produced by Atlas Copco (HL7-3 type) of the efficiency of 10,130 Nm3/h have been built over the compressor produced by CENTAC of the efficiency of 16,500 Nm3/h which produces compressed oil-free air of the pressure of 0.7 MPa to transport loose waste (pneumatic transport) and one turbocompressor HRM704-3 of the efficiency of 10,130 Nm3/h and the pressure of 0.4 MPa which produces compressed air to unload means of transport which provide sorbents for the needs of the sulfur removal system and the fluid boilers.
The pressure and the use of compressed air are constantly controlled via the sequencer which, according to the current needs, regulates the compressors. If the pneumatic transport system and the automation systems are to function correctly, the air has to conform to certain requirements demanded by the process. The main parameter which inflences the assessment of whether or not the air is suitable for the technological process is its degree of dryness. In the building where the compressor system is, there is also a chain of air dryers which adjust the air produced by the compressors for appropriate purposes.
There is a possibility to combine pipelines with the compressed air of identical parameters (although they can be used for different purposes), which increases the reliability of the air supply to all systems based on pneumatics.
