Experimental Study of the Origin of Transverse Cracks in Water Cooled Walls of Controlled Circulation Boilers |
| |
| Abstract: | Transverse cracks,resulting in leakages,frequently appeared in the water cooled walls of a 600 MW power set's HG 2008 type boiler installed in Anhui Ping Wei Power Plant.Investigation and tests were conducted to reveal the origin of cracking.The influence of various modes of operation and that of differing flow volumes of working medium on the temperature of the tube walls,facing the flame,were investigated.The paper describes investigation and test results,analyzes the origin of the transverse cracks and proposes some remedial measures for alleviating or preventing transverse cracking, |
