Repairing Of Bottom Panel Of Boiler In Heating Plant
Abstract
The method for repairing (replacement) of a bottom panel of hot water boiler in Valjevo heating plant, with a power of 30 MW, manufactured by Remming is presented in this paper. Damage that occurred on the bottom panel were a consequence of conditions under which the boiler was working, which resulted in the thinning of pipe walls of the boiler bottom panel. Metal corrosion caused this thinning of pipe walls under the presence of sulfuric acid. The procedure used for repairing, i.e. the replacing of the bottom panel of the boiler is shown. Repair welding was performed using the MAG procedure, combined with gas welding. In addition, the requirements of the welding technology related to successful repairing of the equipment are also discussed.
