Abstract (en)
The method involves detecting the capacity of flue gas generated in a combustion furnace, flue gas temperature and the flue gas composition using a sensor. The detected parameters are used for computing the theoretical value for a steam volume of a steam boiler in a predetermined thermal balance. The theoretical value of the steam volume is compared with a preset reference value, and the combustion power is regulated based on the comparison result.
