Process Engineering

We deliver comprehensive solutions for the optimization of technological processes.

Services (supplies) provided in the fields

Optimization of thermal cycle

Delivery and implementation of the PowerOPTI monitoring and optimization system. Key functions are based on statistical processing of measured data and mathematical and physical modelling:

• Data validation – detection, identification and elimination of gross measurement errors; increased accuracy, correctness and reliability of measurement of operating quantities; recalculation of values of not measured quantities, including their accuracy
• Statistical evaluation of large sets of measured data, extraction of maximum useful information about the behaviour and performance of equipment and technological process (Data Mining)
• Simulation and optimization of processes – determination of achievable or expected values of quantities and performance parameters for the given boundary conditions, which then represent the standard for evaluation, diagnostics and optimization of the performance of equipment and technological process

• Consultancy, advisory service, analyses
• Methodological and software support for creating energy balances

Combustion optimization
A set of methods, procedures, instrumentation and (software) tools designed to optimize the combustion process of solid fuel boilers

• Measurement
  • Measurement of temperature fields in the combustion chamber of the boiler (high-temperature cameras)
  • Delivery of pyrometry system for measuring temperature and absorption coefficient
  • Delivery of spectrometry system for measuring temperatures, emissivity, NOx emissions and temperature dispersion for the purposes of combustion optimization
  • Other special measurements (flue gas analysis, velocity and volume flow rate in powder lines, ON-LINE analysis of grinding roughness of powder mills, …)
• Modelling – modelling and calculations in the ANSYS Fluent program (CFD - Computational Fluid Dynamics program enabling comprehensive solutions to problems in the field of flow, heat transfer and combustion)
• Optimization of economic and environmental parameters of boiler operation; achieving maximum efficiency of energy conversion, reduction of NOx and CO emissions
• Implementation – designing, delivery and assembly within comprehensive optimization projects

Engineering simulators

• Development of engineering simulators (Dukovany nuclear power plant, Temelín nuclear power plant, Mochovce nuclear power plant, Počerady combined cycle power plant; own platform for simulation of dynamic systems and creation of engineering simulators)
• Analyses of operating conditions (dynamic behaviour / transient processes) of power plant units by means of engineering
  simulators (under nominal and fault conditions; in changing technology parameters, regulators and protections; ...)

Asset maintenance process management

• Delivery of comprehensive services (process and data analyses, localization, customization, implementation, support, upgrade, data migration, integration with other applications)
• Partnership with Hitachi ABB Power Grids in the field of Asset Suite – standard software solution among EAM systems, including the following functionalities: Work and Asset Management, Supply Chain Management, Operations Management, Safety and Compliance Management

Boron Concentration Measurement System (AMKB)

Production, delivery and installation of AMKB (boron meters) to increase the safety of nuclear power plants (NPP), in particular during outages and during changes in operating conditions

• The measurement system, which consists of instruments and devices designed for measuring the concentration of isotope ¹⁰B and the concentration of boric acid Н₃ВО₃ in NPP technology, supplemented by methods to ensure metrology continuity
• Types of devices:
  • Calibration boron meter – it is designed for determining the concentration of isotope ¹⁰B or boric acid Н₃ВО₃ in g/kg and the atomic representation of isotope ¹⁰B in % (adjustment and calibration of service boron meters, input control of Н₃ВО₃ at NPP, unknown solutions taken from the technology) with high accuracy
  • Service boron meters – they are designed for continuous measurement of the content (concentration) of the isotope ¹⁰B of boron or boric acid Н₃ВО₃ in g/kg.
    Depending on the location in the technology, they are manufactured in the following versions: Flow, Suspension and Submersible
