Refurbishment Of Yaomeng Boiler No. 1 - Once-Through Boiler With Vertical Tube Technology: Project Summary

Abstract:

<p>The objectives of this project were: <bl> <li>To evaluate the performance of the original boiler unit and conduct heat flux measurements for input to boiler modelling for a new design.</li> <li>To develop a non-intrusive device for flow measurement in individual furnace tubes for the assessment of the waterside performance and to prove the new design.</li> <li>To conduct steam oxidation trials on candidate furnace wall tube materials.</li> </bl></p> <p>The benefits to the operator, Yaomeng Power Generation Limited, (YPGL) from the project have included: <bl> <li>Increased power output capability.</li> <li>Improved load following capability.</li> <li>Improved turndown without fuel oil support.</li> <li>Improved plant availability and part load efficiency.</li> <li>Significant savings on fuel consumption.</li> <li>Reduced emissions.</li> <li>Reduced auxiliary power draw.</li> </bl> All leading to savings on power generation costs. </p> <p>This brochure describes the principles used for the Yaomeng upgrade to a Mitsui Babcock Posiflow boiler and illustrates the clear benefits to boilers designed or converted to utilise this low water mass flux, optimised internally ribbed vertical tube boiler technology. </p> This summary provides information on: <bl> <li>Objectives</li> <li>Summary</li> <li>Background</li> <li>Project Activities</li> <li>Conclusions</li> <li>Potential for Future Development</li> <li>Cost</li> <li>Duration</li> <li>Contractor</li> <li>Collaborators</li> </bl>
