摘要： The composition of flue gas generated in a thermal process, especially in the combustion of bio fuel or refuse-derived fuel, is monitored by measuring the quantity of particles belonging to certain size categories in at least one point along the flow path of the flue gas. Such particle size categories are chosen as objects of the measurement, in which the particles are known to consist mainly of alkali chlorides.

摘要： A method and an arrangement for measuring concentrations of flue gas generated in a thermal process are disclosed. The method comprises the following steps: taking a flue gas sample from the flue gas flowing in a burning apparatus (1) and measuring with a measuring device (9) alkali halides of the flue gas sample. Flue gas is directed to the measuring device (9) through a sampling filter (17). The temperature of the sampling filter (17) is maintained at a temperature range that allows the alkali halides in the flue gas to penetrate the sampling filter (17) in a gaseous form.
