In typical pulverized fuel and grate boilers, there are both high- and medium-temperature deposits. High-temperature deposits are present on platen superheaters and other heat exchangers in the flue gas temperature range exceeding 800°C. These deposits are characterized by high Fe 2 O 3 shares at low contents of SiO 2, Al 2 O 3, and TiO 2.

leaves a large amount of pulverised fuel inside a hot mill. The large surface area of the pulverised coal, as well as the high temperature inside the mill, leads to rapid oxidation of the coal. This results in further heat buildup and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can
and explosions. In order to optimise pulverised fuel flow many aspects need to be taken into account. The major areas of a power plant where improvements can be made are the mills, air/fuel ratio, pipework and boiler. However, before any optimisation can be achieved, measurements which are not only reliable and repeatable, but
