Experimental Investigation of Slag Deposits Removal on Boiler Tubes and Improving Its Heat Transfer

Acoustic grating technology for the purpose of removing slag and fouling deposits in coal-fired utility power plant boilers offers great potential. Conventional slag removal methods including soot blowers and water lance cleaning devices are being only partially successful in removing deposits especially from the downstream side of heat transfer tube bundles in the convective pass sections. They also require considerable maintenance and reduce boiler efficiency when in use. This paper work helps to experiment and the performance of boiler furnaces by understanding the effects of heat absorption, increased draft loss, over-heating of tubes and heat lost. This thereby, confirmed the effect of the lost performance of the overall boiler, and hence helps to develop means of eliminating the growth of either slagging or fouling or both (opacity). This is often found when a furnace starves of air or combustion of such materials as thin paper where fly ash partially fills the combustion chamber. It is necessary to remove this accumulation daily in order to increase efficiency of Boiler and life of tubes/coils. Effective cleaning by using acoustic methods is suggested solutions for cleaning Boiler Tubes/Coils, which improves Boiler efficiency by increasing heat transfer rate.
