What is STEAM MASTERS MASTERWHAT 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.g

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 MASTERprovides engineering details and cost estimation.
