Reconstruction of compressor for technology air and deploying of a control system
”Bright Engineering Ltd” as a subcontractor of ”Honeywell Ltd. ” executed a reconstruction of compressor for technology air pos.402 and implementation of a control system and anti-surge protection system.
The purpose of the system is to perform the functions of automatic control, regulation and emergency protection guaranteeing long trouble-free operation of the aggregates.
- Starting mode;
- Normal operation mode;
- Stop mode (both normal and emergency);
- Functions for regulating the speed of the steam turbine;
- Functions for regulating the basic technological parameters;
- Functions for anti-surge controlling of the compressor;
- Functions for emergency protection;
Informational functions.
The implementation of the regulatory function in the system is performed by acting on the position of valve supplying steam into the turbine and on the anti-surge valve – both in automatic and manual modes.
The modernization of the turbine unit includes replacement of field instrumentation equipment:
- sensors for measuring temperature;
- sensors for measuring pressure;
- sensors for measuring differential pressure;
- level meters for measuring the level;
- sensors for flow measuring by anemometer probe in a set with differential pressure transmitters.
