Turbomachinery for Nitric Acid Plants - MAN Diesel & Turbo

Steam turbine for a 1,230-t/day two pressure plant P = 9,410 kW n = 7,973 rpm
Steam turbine
The steam turbine is normally fed with
steam generated in the process. In a
few cases this process steam is utilized
for other purposes and the steam turbine
is replaced by an electric motor.
In nitric acid plants the steam turbine
not only has to provide the normal driving
power but also the startup power of
the HNO3 turboset as initially the tail gas
expander does not deliver any power.

The start-up power may be more than
twice the normal power.
There is also an increasing demand for
turbine designs which allow extraction
of a certain steam quantity for process
purposes or for an additional generator
drive.
For these applications MAN Turbo provides
condensing steam turbines of
the reaction type with and without extraction
or steam admission.
