Abstract

The present invention relates to a method of measuring the amount of pulverized fuel in a pulverized fuel fired furnace (2) and a method of controlling a combustion process in a pulverized fuel fired furnace. According to the invention, the heat radiation emitted by the flame (32) of a pulverized fuel burner (11) is measured over a predefined area (31), the combustion air feed rate (5, alpha ) to the burner is determined simultaneously, and a burner-specific corrective computation (20) is performed to determine the amount of pulverized fuel.
