- Thermocompressor model improvements:
- 1D Model - S&K Data - method has been improved by using excess energy to either superheat or condense steam. In most cases this will result in a reduced heatflow and may change the final product temperature.
- Full Steam 1D Model - method has been improved by using excess energy to either superheat or condense steam. In most cases this will result in a reduced heatflow and may change final product temperature and pressure.
- HeatFlow - sign reversed to correctly report Energy Out - Energy In.
- Precipitator3 - Bound Soda calculations correction for Hunter and Fixed% methods.
- Existing projects will retain old calculation methods (and results).
- User would need to tick the option "UseCorrectedBoundSoda" (local to each precipitator unit) to upgrade to the new calculation methods.
- User would need to retune the bound soda factors to re-align the bound soda precipitation values.
- Preciptitator3 - Agglomeration Cutoff fix in Steady State
- This applies to users using Precipitator3 in with PSD Method and Agglom.Cutoff option only.
- Existing projects will retain the original results if no action is taken.
- User would need to tick the "Agglom.UseCorrectedCutoff" option, (local to each precipitator unit) to upgrade to the new calculation methods.
- User would need to check the results and retune as required.
- This will give a correct size distribution curve and also ensures that the model gives the same results as Dynamic projects with the same parameters when run to steady state. See Preciptitator3 for sample results comparison.
- Project using species with missing S25 data may find the stream entropy value may have changed. Species with missing S25 data will be assumed to have value of 0 at 0°C.
