1. Only two thermocouples were used - one in the water tank from which the pumps got the water, one at the steam outlet outside the container.2. I talked a lot with the examiner Fioravanti. He seemed very experienced and he didnt believe a single thing in the discussion on the steam quality. He said that there are three stages in steam systems.
1. Water being heated.
2. Water boiling and steam being produced. Steam temperature is only defined by pressure here. At atmospheric pressure its 100 degrees centigrade.
3. Steam transported away from the water and heated further. This is basically dry steam.
The only case when you have low steam quality or droplets or liquid water in this steam is in long or poorly isolated tubes fro steam transport. Steam then condenses and there will be a flow of water together with the steam.
This is not the case with the Ecat he said, and he saw no doubt what so ever on the steam quality at atmospheric pressure and 105 degrees.
3. Two common water meters - one for each pump that was running.
4. The generator supplied power also to the pumps and the four fans on the dissipators (nominal 4x5 kW).
