Abstract

Method for controlling of combustion in real time for example in a fluidizised bed furnace. The invention is suitable especially for controlling combustion of fuels that have variable composition and are difficult to combust. Such are for example waste fuels and biomasses. In the method flue gas is taken from the furnace, the flue gas is led to a washer to interact with the washing media of the washer and at least one property of the washing media of the washer is measured for evaluating properties of the gas phase indirectly.
