CLEANING METHODS OF HEAT SURFACES IN BIOMASS-FIRED BOILERS: A REVIEW
Journal Title: World Journal of Engineering Research and Technology - Year 2018, Vol 4, Issue 5
Abstract
In biomass-fired boilers serious deposits are formed on heat-transfer surfaces which cause decrease in efficiency of energy production. Slags and fouling cause troubles in boiler operation even the blockade of the plant. In this paper various methods for elimination of slags and fouling from the heat surface are presented. An overview of the offline and online cleaning techniques of dirty surfaces is described. The main attention is directed toward soot blowing techniques, rapping devices, detonation-wave technique, sonic-wave cleaning and pneumoimpulsive method. Advantages and also disadvantages of methods are reported. It is concluded that is not a method which is universally suitable for cleaning surfaces for all types of biomass-fired boilers. Future investigation in problem is necessary.
