MODELING & SIMULATION HRSG
DS Power offers complete thermodynamic modeling services and operational simulations for horizontal and vertical flow HRSGs, identifying and quantifying thermal losses. These services support decision-making related to commissioning, turbine upgrades and turbines and planning cleaning maintenance, always based on hard data. data.
The Thermodynamic Modeling services offered by DS Power are carried out using Power Plant Simulator and Designer™ software (PPSD), developed by KED. O PPSD é PPSD is the main tool for this work, as it allows the complete model of the plant to be integrated plant model, incorporating the steam turbine and the steam cycle balance, allowing for a comprehensive and accurate comprehensive and accurate analysis of the entire plant operation.
DS Power’s frequent applications include:
- Simulation of the fouling factor to evaluate thermal energy losses and power (MW) in the combined cycle, helping to make strategic decisions regarding the HRSG cleaning.
- Technical audit to assess the quality and results, before and after the processes processes.
- Drawing up QT diagrams to evaluate the temperature performance curve of the exhaust gases and the working fluid, identifying opportunities to improve operational efficiency. operational efficiency.
- Analysis of the gas flowpressure drop performance curve along the HRSG heat exchangers, identifying opportunities to improve operational efficiency. efficiency.
- Simulations for turbine commissioning and upgrades, optimizing performance and integration with HRSG.
Benefits
IDENTIFIES THERMAL ENERGY LOSSES
The modeling identifies the amount of thermal energy wasted due to fouling, allowing measures to be taken to recover this energy and increase steam generation.
IDENTIFIES MW OUTPUT POWER LOSSES IN THE COMBINED CYCLE
Guarantees the quality of the cleaning process by validating the results obtained. Minimizes uncertainties, reduces maintenance costs and improves operational reliability.
PLAN THE BEST TIME TO CLEAN HRSG
It helps to identify the ideal times for cleaning, optimizing costs and maximizing plant availability.
PERFORMANCE CURVE ANALYSIS (QT DIAGRAM AND FLUE GAS DROP PRESSURE)
HRSG's thermal and flow analysis in heat exchangers makes it possible to identify temperature deviations and gas flow restrictions that affect operating efficiency and increase fuel consumption.
