Heat Flex®
Heat Flex® is a program that calculates
steam turbine regenerative cycle heat balances. The Heat Flex®
program will model steam systems with only one feedwater heater and up to a
maximum of five feedwater heaters. Both open direct contact heaters and
close type heaters are available. The steam turbine performance is
estimated based on a user input overall efficiency.
Program features:
-
The design point and off design points can be calculated.
-
The turbine inlet steam flow or generator power may be input.
-
The turbine can be direct drive or geared.
-
The user can select which type of heater to use. The terminal difference
and pressure drops are user selectable.
-
The user can enter the system losses, plus the inlet steam pressure and
temperature losses.
-
Process steam can be extracted from the cycle and reinjected either into the
condenser or the deaerator.
-
The feedwater heater operating pressures (temperatures) can be adjusted to meet
the users requirements.
-
The turbine first extraction point can be either variable (bleed steam) or
automatically controlled fixed extraction pressure.
