COMBINED HEAT & POWER INDUSTRIAL PLANTS WITH GAS TURBINES & HEAT RECOVERY STEAM GENERATORS - FEASIBILITY STUDY METHOD AND CASE ANALYSIS

摘要

The Combined Heat & Power Industrial Plants (CHPIP) using Backpressure Steam Turbines (BST CHPIP) have low ratios power vs. heat, Therefore is difficult for them reaching the norms for "high efficiency cogeneration" (HEC). That's why the paper analyzes the CHPIP with Gas Turbines & Heat Recovery Steam Generators (GT&HRSG CHPIP). The main paper's objectives are, from the theoretical point of view: establishing an accurate methodology, giving advices for choosing the main equipments and making the technical section of feasibility studies on GT&HRSG CHPIP From the practical sight: applying the methodology in a case study for a CHPIP, in order to establish if this one could reach the Romanian HEC norms.
