Parameters/Specification are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc.

The boiler capacity can be expressed by the rated evaporation capacity or the maximum continuous evaporation capacity. The rated evaporation capacity is the amount of steam continuously produced per unit time under the specified outlet pressure, temperature and efficiency. The maximum continuous evaporation is the maximum continuous production of steam per unit time under the specified outlet pressure and temperature.
