Heat loss is a process which causes useless heat in operation. Heat loss not only occurs in boiler (steam boiler heat loss) but also occur in steam turbine generator. The following below are types of heat loss in steam turbine generator.
- Internal heat loss, include:
b. Heat loss in nozzle
c. Heat loss in rotation blades turbine
d. Heat loss because of output velocity
e. Heat loss in blade steering
f. Heat loss due to friction disc and ventilation
g. Heat loss due to free space
h. Heat loss due wetness steam
- External heat loss
The external heat losses generally due to mechanical friction such as between shaft and bearing, regulatory mechanism, lubricating oil pump, and leak in the gasket.
