What is STEAM MASTER
WHAT IS STEAM MASTER?

• While STEAM PRO is the design program for
  conventional steamcycle plants, STEAM MASTER is
  the associated simulation program foroff-design
  calculations.
• Use STEAM MASTER to evaluate designs at various
  ambient conditions and loads.
• All STEAM MASTER hardware inputs has
  automatically been initialized based on the
  design,which makes it possible to perform
  calculations by just changing a few parameters.
• Since STEAM MASTER hardware inputs are editable,
  the model may be fine tuned to matchan existing
  plant or vendor data.
• In combination with PEACE (Plant Engineering and
  Construction Estimator), STEAM MASTER provides
  engineering details and cost estimation.

Open Files
Load existing STEAM MASTERfile or import STEAM
PRO file.
Activating the STEAM MASTER programwill display
this input screen for selectingthe desired
file. All STEAM MASTER models are based on
aSTEAM PRO design. STEAM MASTER will allow the
user to dooff-design calculations, such as part
loadand varying ambient conditions.
3
Input Topics
At any time during the session the user canpress
compute to activate the calculation.
All the main topics arearranged horizontally
tounderline the fact that,contrary to design
inSTEAM PRO, off-design inSTEAM MASTER has
nonatural order of editingthe topics.
Green topicsare available forPEACE
licensesonly, and theirinputs primarilyimpacts
the costcalculations.
The user may goback to STEAM PROto redesign
theplant if necessary.
The input screens apply graphicaldisplays to
ease the use of the program.
4
Editing Inputs
Confirm actualambient conditions.
Select the appropriateplant control parameter.
Adjust fuel input forpart load calculations.
Specific help is always available for the
highlightedinput through the Guidance window.
5
Detailed Inputs
Each main topic holds a set of input tabs for sub
topics related to themain topic. E.g.
highlighted main topic is Steam Turbine.
Sub-topics ofthe Steam Turbine are ST Controls,
Stage Groups Controls, etc.
Set desired pressureand temperature forthe
controls.
Each sub-topic tab letsthe user set inputs
forthat specific sub topic.
Select the appropriate steam turbine control
method.
Again notice the guidancefor the highlighted
input.

Hardware Models
STEAM MASTER is based on hardware models with
editable sizeand dimensions. This allows
theuser to adjust values to match anexisting
plant or a vendors data. Since STEAM MASTER
applieshardware models the heat
balancecalculations will reflect any changein
the hardware. Cost of the plant will also
berecalculated taking the changesinto account.
Main boiler dimensionsare editable for theuser
to input data.
7
Hardware Details
Different fin-tube typesare available Bare,
Solidfins and Serrated fins.
Selection of different materialsis available as
well.
A pulldown listallows forselectionof the
desiredelementof theboiler.
Even details of tubebundle design suchas tube
length,bundle width,number of rowsand tube
diametermay be edited. This flexibilityallows
the user tomatch known plantdata.
Graphical displays help theuser visualising the
tubeand tube bundle geometry.
Economiser (ECO) has beenselected as example.
8
Program Options
Common unit systemsfrom around the worldare
supported by STEAM MASTER.
Compute will activatethe calculation engineand
(after convergence)display the outputsfrom the
calculation.
Also the steam property formulation may be
selected. Available formulations Thermoflow
Proprietary (STQUIK) IFC-67 (previous ASME
standard from 1967) IAPWS-IF97 (current ASME
standard from 1997)

Output Topics
Output is displayed in three groups Graphics
(graphicaldisplay of thermodynamic results),
Text (text and tables ofsame), and PEACE (size,
weights and cost). Each topic holds a large
number of tabs each describing partof the plant
results.
Plant Summarydisplays themain output.Details
can befound on thesubsequenttabs.
10
Graphics Output
Detailed results for the steam turbine displaying
steam conditionsat the steam turbine inlets and
conditions of all extractions.
Desired values are met through the STcontrol
(MVL) and boiler control (sprays).
11
Text Output
At any time the user maygo back to edit the
inputs.
Text display of the outputsis organized in a way
togive the user both a goodoverview and
detailedinformation about theplant performance.
Plant Summary willgive the main plantdata,
whereas thesubsequent tabs willdisplay more
detailedinformation.
12
Tables Output
Multiple runs may be performed applying the
ThermoflowMacro for studies of parameter
variations.
The Tables tab holds data for allthe components
in the plant asseen on the left. By highlighting
the desired plantcomponent, data for
thatcomponent will be displayed. Note that some
of thecomponents are characterized
byabbreviations, e.g. FWH is feedwater heater,
ECO is economiser,CS is convective superheater
andWCC is water cooled condenser. Furthermore a
table describingthe fuel and a table with
steamcycle streams are available. Each table can
be saved as a.CSV file, which can be loadedinto
Excel.
13
PEACE Output - Schematics
Schematics showing the main components in the
plantare selected through a Schematics List.
Examples areSite Plan, Boiler, Steam turbine
(as shown), Condensers,Cooling towers,
Feed-water heaters and pumps.

PEACE Output Equipment Data
If the selected equipment (in this case Steam
Turbine) holds sub-elements,each of those
elements will have equipment data tables of their
own.
Each tab represents amajor part of the
powerplant. Selected for displayis the steam
turbine. The tables will displaydetailed
information aboutsizes and weight of
theselected element or groupof elements of the
plant.
15
PEACE Output Cost Report
Cash Flow will tell the user howthe economy
throughout thelifetime of the plant will be.
Project Cost Summary is displaying the total
cost ofthe power plant.
Each tab represents a part of the total cost
ofthe power plant.Selected for display isthe
SpecializedEquipment. The tables will
displaydetailed informationabout equipment
andlabor cost.
Reference cost is thecost at a referenceUS
Site, whereasEstimated cost is thecost at the
actualsite.
16
Multiple Runs Edit Input
Thermoflow Macro enables the user to
performseries of calculations in an easy and
fast way.
Part load calculations with constant ambient
conditions.
Inputs to vary in themacro may be selectedfrom
an extensive listof inputs availablefrom STEAM
MASTER.
Full load calculations with varyingsite cooling
water temperature.
17
Multiple Runs - Output
Summary displays a fixedlist of main output data.
Any of the general tabs allows theuser to define
which data (outputsas well as inputs) to display
in thatspecific table. All tables can be
exported to Exceldirectly or saved as a .CSV
file forlater load into Excel.
Plots can be created.As an example Plantnet
efficiency vs. Fuelinput.
For each case STEAM MASTERoutput can be
displayed.
