PowerPlantSimulator&Designer

 

Program PowerPlantSimulator&Designer is designed for engineering complex heat exchangers e.g. steam boilers, power stations…etc

The PowerPlantSimulator&Designer allows the user to build quickly a graphical schematic representation for a plant in a graphical user interface (GUI) by selecting from a library of predefined power plant elements to simulate their operation. Element connections for fluid-flow paths, mechanical couples, or signal/logic flow paths are based on connectivity rules, defined for each element. The connection of elements is intuitively implemented with mouse operations allowing only valid connections.

Some elements are hierarchical and can hold nested groups. Such an organization helps to make schemes of complicated objects with no limitations on element quantity.

 

Different boiler types:

 

  1. Natural circulation boiler
  2. Forced circulation
  3. Force flow boiler (once through boiler)
  4. Benson-boiler (supercritical)
  5. Municipal waste incinerator
  6. Fire tube boilers
  7. Hot water boiler
  8. Fluidized bed combustion
  9. Other heat exchangersHeat transfer medium
  10. gases with real properties (Joule- Thomson- effect) (more than 20 different gases)
  11. all fluids (user defined)
  12. water with two phase flow
  13. dust and slag with infrared radiation

Other remarkable features

 

  1. Gas- Turbine exhaust gas can also be introduced into the combustion chamber. The turbine exhaust can be considered as oxygen carriers for the combustion calculation.
  2. the temperature at the end of the combustion chamber and fire tube can be entered.
  3. radiation from the combustion chamber can be transmitted onto the superheater bundles.
  4. turbine exhaust gas can be entered into Nm³/s or kg/s and/or the gas composition in Vol% or kg/kg.
  5. the thermal conductivity of the tubes is computed in dependence of tube material and the temperature.
  6. feed water pressure and the drum level are controlled automatically
  7. spray coolers and cooler in the drum are controlled by the temperature after the next heating surface.
  8. the fuel flow can be controlled in dependence of the desired steam production, independent of the steam temperature.
  9. several fuels can be mixed and burned
  10. calculation of efficiency (heat balance) in dependence of the exhaust flue gas temperature and composition, boiler surface conduction & radiation, loss in combustion chamber (unburned fuel), losses through ash and chemical not fully burned fuel (CO).
  11. design calculation of heater surfaces
  12. in almost every place of the flue gas draft can be taken recirculation flue gas and injected again not only in the furnace.
  13. flue gas flows and steam/water flows an be divided up and be combined again.

  • Incomplete combustion and additional complete combustion
  • Heat transfer for fluidized bed boilers and fluid bed heat exchangers

 

Usually for such number of calculations are used several programs and the results of the one program must be inserted manually into another program as initial data. That is one reason why the usage of the PowerPlantSimulator & Designer program gives such advantages:

  1. Fast calculation of the different boiler designs and as the result – helps to choose the best choice for projecting or reconstruction;
  2. Calculation of the transient stages on the projecting stage;
  3. Combine calculation of the heat scheme of the power plant with exact boiler calculation;
  4. Analyze static modes with different working conditions (fuel contents, dust presence on heat surfaces, feed water temperature difference…) and possible construction changes;
  5. Calculate natural circulation in drum-type boiler in current working mode and find minimum possible load by circulation condition;
  6. Analyze transient stages of the boiler (warm-ups, load changes…) in order to improve operational instructions of the boiler and future perfection of the startup devices;
  7. Unified elements and Graphic User Interface (GUI) minimizes time spending for the creation of the adequate mathematical model of the equipment. Qualified specialist in boiler construction can easily work with program, make and improve calculation models without any knowledge in programming;
  8. Comfortable data representation in Integrated Development Environment in different cases (data tables, tree views and graphs);

Ability of bi-directional data transfer between calculation program and Microsoft Excel for future data analysis and data representation.Mathematical model is adequate to real equipment because of:

  1. Application of the widely used calculation methods;
  2. Improved calculation method of heat exchange calculation, with division of the surface into small zones;
  3. Improved equations of the heat exchange considering the radiation, which was derived from the differential heat exchange equation, formulated according to physical processes specialties;
  4. Usage of the big database of the physical medium properties, which can be easily extended by user;
  5. Usage of the all-modes dynamic boiler model allows to calculate different stages with any combination of the disturbing influences with high static and dynamic precision;
  6. Usage of the special parameters, which characterize real state of the each heating surface, allows adapting mathematical model to the real equipment.Operational experience of the program usage confirms it’s highest efficiency and accuracy
