Client Background
Youngheung Power Plant is a coal fired power station located on Youngheung Island, 40 kilometres from the South Korean capital of Seoul. Youngheung Power Station had previously relied on retractable steam soot blowers to prevent build up and blockages within their SCR’s, however, due to the deteriorating condition, reliability and performance of the steam soot blowers the operating efficiency of this equipment soon declined. After analysing the high costs of replacing and maintaining the steam soot blowers, plant personnel chose to look for a more cost effective and reliable solution to the problems they were experiencing. Their search led them to the Primasonics website and our Korean agents, Artronix System Co Ltd.
The Approach/Solution
Artronix System Co Ltd arranged a site visit with personnel at Youngheung Power Station to discuss in more depth the benefits and capabilities of Sonic Soot Blowers and obtain the relevant application information and drawings to allow Primasonics to establish the most suitable model of Sonic Soot Blower and installation locations. Following the submission of recommendations and quotation from Primasonics, Artronix won the order for 16 Q3 (120 Hz) model Sonic Soot Blowers. Installation and commissioning of equipment took place in June 2010 and was supervised by Primasonics Technical Director, Alex Bergus, who attended site to ensure the smooth transition between cleaning methods.
The Result
The installation of the 16 Sonic Soot Blowers at Youngheung Power Station saw an increase in the scale removed and a decrease in the differential pressure in comparison to the 3 months prior to installation. Plant personnel were so impressed with the results and low operating and maintenance costs that the following year they installed another 8 Q3 model Sonic Soot Blowers on their #3 SCR and are now planning the installation of a further 8 units towards the end of 2013.
