3 days EMT/COGENE-E
- Graduate engineers and technicians whose activities are related to the design and/or operation of these installations: engineers and technicians from engineering companies, technical & HSE support, operation team, personnel from insurance companies.
- This course deals with cogeneration units in existing plants or new projects.
- Upon completion of the course, participants will be able to:
- describe the process conditions related to the combined production of thermal and mechanical energy,
- assess and follow up on the performance of the different equipment of a cogeneration unit,
- analyze the operating conditions of a cogeneration cycle.
- No prerequisites for this course.
Ways and means
- Several practical applications related to actual industrial cases.
COGENERATION: DIFFERENT CYCLES 0.5 day
- Operating principle 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.
- Mechanical and thermal energy split.
COGENERATION: PRODUCTION OF STEAM 0.75 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.
COGENERATION: GAS TURBINES & WASTE HEAT RECOVERY 1 day
- Operating principle - Operating conditions.
- Energy balance and energy performances of each elementary operation: compression, combustion and expansion. Energy performances and efficiency.
- 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.
