In the article some issues have been presented regarding a tube probe for collecting deposits from the vicinity of the boiler superheater, fuelled by solid fuels. The probe is cooled by the inside flow of compressed air which later goes into combustion chamber. An algorithm of heat-related calculations has been proposed taking into account the exchange of heat between the flue gas and the external surface of the probe as well as the reception of heat from steel by the flowing cooling agent. The quality requirements have been defined for steel to be used in construction of the deposit probe. The temperatures arrangement should correspond with the temperatures of tubes of the superheater. Preliminary tests of the device have been conducted in the pulverized-fuel boiler OP-430 fuelled by pulverized bituminous coal with addition of biomass. The probe of deposits has been placed above the combustion chamber in the vicinity of the superheater.
