Steam output: indicates how many kilograms or tons of steam are required per hour. Attention: When calculating the steam required, the internal steam consumption should be considered.
System output = boiler output – own use
The own use by the feed water treatment is usually between 5 and 20%. It can be greatly reduced by waste heat recovery.
Do peak loads occur only occasionally or is the system operated with full loads over long periods of time? If necessary, the boiler size can be reduced by a steam accumulator (cost saving).
Pressure: the most important criterion is the average operating pressure. The safety pressure of the boiler is always higher than the operating pressure.
