Steam generation


Higher temperature exhaust gases can be used to produce steam. Due to its high temperature, the steam can be used in many different ways for heating processes.

EXAMPLE: Steam generation: KWK plant at Euroglas in Osterweddingen
Exhaust gas: 100,000 Nm³/h, 550 °C
Steam: 16.2 t/h, 42 bar, 425 °C
Power generation: 3.1 MW

Why does steam contain so much energy?
To find out how much energy is in steam, you can conduct a short experiment: Take a saucepan filled with 2 litres of water and place it on a hotplate. Set the hotplate to the highest heating level. After a few minutes the water has warmed from 10°C to 100°C and starts to evaporate. Now wait until all the water has evaporated. It is highly likely that you will have to wait longer than half an hour.

The energy required for evaporation is much higher than the energy required for heating. This effect can also be used the other way around. If the steam is collected and led to different consumers, it can condense there. The thus set free energy is very high. The condensate will remain and will be carried back to the steam generator to be used again.
