- 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 AND 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.
