2. Combined Heat and Power (CHP)
What is CHP?
Efficient way to generate heat and power together
What does CHP provide to the rest of the project?
Electricity
Cooling water
Why is CHP needed?
Improve fuel efficiency, power quality, and energy cost predictability
Reduce grid investment, ratepayer investment, and system vulnerability
Support competitive electric power industry structure
Our Goal
“To optimize energy production and consumption of the whole plant .“ - Prof. Perl

4. Power Block

5. Power block- Gas Turbines
Microturobines - Power output ranges kW, with the electrical efficiency 25-30%( in recuperated and 15% in unrecuperated), basically very small combustion turbines( turbocharchers)
Aeroderivative - they are usually more expensive than products designed and handle load changes more quickly no heavy construction.
Industrial - are exclusively for stationary power generation and are available in flexible capacity range. They are generally less expensive

6. Power block- Steam Turbine
Types
Backpressure/ Condensing
Power Output
from MW
Inlet Steam Temperature °C
Inlet Steam Pressure
bar( psi)
Exhaust Pressure
Backpressure bar( 145psi-232psi)
Condensing bar( psi)
Backpressure Steam Turbine (non-condensing steam turbines) – produces less useful work than the condensing turbine but the steam exhaust at above atmospheric pressure used for other steam applications
(Power generation efficiency 15-35%)
Condensing Steam Turbine - generally used in CHP systems, produces maximum useful work per lb of steam input (Power generation efficiency 30-40%)

7. Cooling Water

8. Boiler Feed Prep What is boiler feed prep?
Provide pure water for boiler
Why do we need boiler feed prep?
Maximize life of boiler, steam turbine, and condenser
Maximize process performance and productivity
Reduce operation costs and maintenance expenses
Design Basis
Production: Ensure provide enough water for boiler
Feedstock: Reclaimed water from cooling water system
Outcomes: removal or control of Ca, Mg, Si, Al, high alkalinity, bicarbonate alkalinity
