Course Content

COGENERATION: DIFFERENT CYCLES - GAS TURBINES & WASTE HEAT RECOVERY

1.25 days

  • Operating principle and operating conditions of cogeneration and combined cycles - Typical schemes.
  • Main parts of the different cycles:
  • Boiler, steam turbine (back-pressure or condensation).
  • Gas turbine, waste heat recovery boiler.
  • Energy balance and energy performances of each elementary operation: compression, combustion and expansion.
  • Efficiency enhancement, heat recovery from exhaust gases (air preheater, waste heat recovery boiler).
  • Different operating modes (simple waste heat recovery, post-combustion, separate boiler) and performances.
  • Application: comparison of performance, mechanical and thermal energy split.

COGENERATION: PRODUCTION OF STEAM

1 day

  • Boiler Feed Water (BFW) quality, description of the physical and chemical required treatments.
  • Description of conventional boilers and waste heat boilers: water circuit, steam circuit, fuel circuits.
  • Operating conditions - Fuel consumption per ton of steam, depending on boiler type and operating conditions.
  • Main process control loops: boiler feed water, pressure and steam temperature, combustion, flue gas circulation draft.
  • Combustion monitoring, analyzers, aim and meaning of each measured parameter. Safety equipment & sequences.

COGENERATION: STEAM END-USES

0.75 day

  • Steam as a heating medium and mechanical driving fluid.
  • Steam pressure level requirements, depending on the end-use. Steam network balancing.
  • Steam as a heating medium: conditions for its distribution and efficient utilization.
  • Steam turbines: operating principle, expansion work and efficiency, and produced energy.
  • Static expansion: expanded steam characteristics, steam de-superheating.
Ways & Means
  • Several practical applications related to actual industrial cases.
