Steam generation testing objectives

For a 1 thermal MW considered for the steam generator, first process simulations lead to H2 and 02 mass flow rates respectively of the order of 90 kg/h and 730 kg/h. The water mass flow rate required is about 820 kg/h. It is worth mentioning that this 1 thermal MW objective will depend on the availability of corresponding stacks of electrolysers. If only a few hundreds of kW stacks could be tested by 2013, PROHYTEC is designed to function at this lower power. 

In parallel to these developments, the capability (modularity) of PROHYTEC to test HTSE at a higher thermal power has to be assessed in an objective of performance testing by 2015. Typically, calculations have shown that the electrical power which could be injected in the HTSE is about 2.5 MW when the exchange thermal power at the steam generator level is about 0.8 MW. When the available power will be about 7.8 MW the thermal power could be of 1.9 MW and the electrical power injected in the HTSE of about 5.9 MW. This increase in power could match the objective of 2015 but is still to be defined. 

The objectives of corrosion testing and associated monitoring of chemical, stress, and thermodynamic conditions in steam generating cycles are ...
