Cleaning systems for convective sections of a waste incineration boiler
High fly ash load in the flue gas of waste and biomass incineration boilers causes deposits on the tube bundle heat exhange surfaces. To meet the boiler efficiency and to maintain the required temperatures of the downstream located plant components, the tube bundles must be cleaned periodically. In order to achieve the most constant possible conditions and for safety reasons, the cleaning should be carried out online during the boiler operation and without any personal intervention in the boiler. The cleaning procedures practiced in the plants are described below.
