THERMAL FATIGUE FAILURE IN BED EVAPORATOR TUBE

2019-7-29  THERMAL FATIGUE FAILURE IN BED EVAPORATOR TUBE OF AN AFBC BOILER By K.K.Parthiban, B. Tech(IIT-Madras), M.E Thermal Engineering- RECT Trichy This paper is about a repetitive evaporator tube failure experienced in an AFBC boiler. The mode of a bed evaporator tube is generally erosion or overheating or water side corrosion.

of In-Bed Tube Erosion Combustion (FBC) System

tube, in-bed tube erosion could be reduced more than threefold. According to these results, the finned/ball-studded tube is considered to be the most effective device in terms of tube erosion in FBC. A higher weight loss rate was observed on the bottoms of tubes in regions of upward moving bubbles relative to the tube surface.

Fluidized Bed Boiler - an overview ScienceDirect Topics

The air-distributor grate of CFBC is less critical than that of BFBC, since erosion of bed internals and heat exchanger tubes is a major concern for BFBC. In CFBC, air-distributor grates are narrow, deep, and operate at much higher velocity to distribute the fluidizing air uniformly over the cross-section of the bed.
