| Kyma Steam Analyzer (KSA) is an analyzing tool for optimum steam turbine plant operation. It consists of an advanced software package for calculation of heat balance and component efficiencies, engineering support for instrumentation upgrading and commissioning of the system. The commissioning involves calibration of instruments, engine performance trials and pinpointing of non optimum operation or deficient components.
The software run on a personal computer under Windows™ XP. The KSA and KSP system can be integrated for operation on the same computer. This means that input data required for the KSA system can collected from IAS systemÂ
No previous computer experience is necessary for operation.
Each system is tailormade for the specific plant. The units in the input and the output forms are normally the same as on the local instrumentation.
The system can be used for all normal at sea conditions with stable operation of the steam plant. As this is mainly a diagnostic tool, it is sufficient to do an engine trial once a week or when the vessel schedule permits.
The input data are recorded from the ship's instrumentation and from sensors installed during the delivery of the system. Normally from the IAS system. If not all variables are on-line, manual inputs can be applied.
The inputs are fuel (gas) consumption, distillate production, power output, propeller revolution and physical properties of steam and water for all major components. Data for combustion air and flue gas are also measured. |

Based on the input data to the computer a performance report is printed. The printout shows the condition of the plant and the components compared to design or trial data. The calculations will specify component losses and what they represent in excess fuel consumption. Any non optimum operation will be specified in the printout. A plant operation check list indicates operating status of normally adjustable parameters. An error check list is printed for a component or parameter out of range.
For the major components graphical presentation is used to express component efficiency relative to a design or trial curve. The deviation from reference is seen both graphically and numerically including deviation in fuel consumption.
The output information from the system will specify where to find the faults.
The program also calculates torque distribution between HP-turbine and LP-turbine with warning for gear overload.
The calculated heat balance and flow diagram shows the physical conditions of steam and water and the mass flows in the plant. Together with the component efficiency calculation and a plant operation check list, this gives the operating engineers the information required to run the plant at an optimum condition. |
