American Society of Mechanical Engineers Performance Test Code 34 – ASME PTC 34, Waste Combustors With Energy Recovery: What Is PTC 34 and How Can It Help You?
20th Annual North American Waste-to-Energy Conference, 2012Co-Authors: Stephen G. Deduck, Lambert XiaoAbstract:ASME PTC 34 is a Test procedure for determining the thermal capacity and thermal efficiency of systems (typically boilers) combusting waste fuels (typically Municipal Solid Waste - MSW) and for determining the higher heating value (HHV) of those waste fuels. The basis of the procedure is more commonly known as the “boiler-as-a-calorimeter” method. The need for PTC 34 arose from the difficulties in obtaining representative samples and accurate fuel analyses using traditional laboratory methods such as a “bomb calorimeter”. Unsuccessful attempts were made to come up with a larger “bomb calorimeter”, so a committee was formed to create PTC 34 which was published in 2007.ASME PTC 34 is firmly based on the widely accepted boiler Test Code, ASME PTC 4 – “Fired Steam Generators”, but has several different challenges in having to measure the relatively difficult parameters of flue gas flow and moisture and fuel and ash quantities. As a result, the uncertainty of PTC 34 is higher. However, the philosophy of correcting results to standard, contract or reference fuel analysis is the same in PTC 4 and PTC 34. So, an industry approved Code for acceptance Testing is available to the Energy-from-Waste industry.ASME PTC 34 can be used in several ways depending on the analysis time period. It can be used for typical short-term, i.e. 8-hour, Performance or acceptance Tests, again with the ability to correct to reference fuel analyses. Alternatively, multiple “samples” of fuel HHV can be obtained using PTC 34. With the Test data and HHV results, accurate correlations can then be generated to be able to make adjustments for varying fuel conditions in longer term, i.e. 7-day, throughput capacity Testing. The 8-hour HHV determinations can also be used to validate or even calibrate correlations used over the life of a waste combustor as operating parameters stray from their normal ranges. Taken to the extreme, PTC 34 can be used as a basis for near-real-time monitoring of fuel quality or possibly combustion control. Recent developments of laser-based flue gas moisture instruments and the economizer heat balance method for determining flue gas flow make this leap possible.The goals of this paper are to make the industry more aware of ASME PTC 34 and the guidance it contains on making the difficult measurements, to promote its use as a standard in the industry and to instill confidence in the time-Tested and accepted process of making corrections to Test results for off-design fuel characteristics.Copyright © 2012 by ASME

Thermal Performance Test on Nuclear Power Station: A Case Study in Taiwan
Nuclear Technology, 2017Co-Authors: Yea-kuang ChanAbstract:AbstractThe baseline and verification Performance Tests based on American Society of Mechanical Engineers (ASME) Performance Test Code 6 (PTC 6) for Maanshan Nuclear Power Station (MNPS) Unit 1 were successfully conducted prior to and after the replacement of a high-pressure turbine rotor. In order to verify that the actual improvement in electrical output resulting from this replacement meets the vendor’s guarantee, measurement uncertainty analysis of the thermal Performance Test was calculated. Two verification Performance Tests show that the deviation for the corrected heat rates of the two Tests differs by only 0.11%, which therefore meets the ASME PTC 6 requirements where the deviation between two Tests should be within 0.25%. Thus, the quality of the Test results is acceptable. After accounting for the Test uncertainty, the Test results demonstrated that the improvement in gross electrical output compared to the baseline Performance Test is between 12.57 and 22.63 MW(electric), which is higher than ...

The Performance Test was conducted in order to verify that the actual improvement in electrical output resulting from the replacement of the high-pressure turbine meets the vendor’s guarantee. A total of two Performance Test runs was conducted in accordance with the American Society of Mechanical Engineers Performance Test Code (PTC) 6. The measured electrical powers for the two Test runs were 977.4 and 975.0 MWe, respectively, and the average value was 976.2 MWe. After correcting the electrical power to the rated conditions specified in the Performance Test procedure, the gross electric output was 983.2 MWe. The corrected heat rate for the two Performance Tests were 10365 and 10353 kJ/kWh, respectively. The deviation between two corrected heat rates was 0.11%. Since the acceptable deviation between...

Measurements of hydrodynamic forces, surface pressure, and wake for obliquely towed tanker model and uncertainty analysis for CFD validation
Journal of Marine Science and Technology, 2006Co-Authors: Kenichi Kume, Jun Hasegawa, Yoshiaki Tsukada, Junichi Fujisawa, Ryohei Fukasawa, Munehiko HinatsuAbstract:This article presents hydrodynamic forces and moments, surface pressures, estimated side force distributions, and wakes under oblique towing conditions for a practical tanker model (model KVLCC2M), which was designed by the Korea Research Institute of Ships and Ocean Engineering (KRISO). Ship offset data is readily available and can be obtained from the Internet. The model ship has no appendages and no rudder. Trim and sinkage were adjusted to zero in the static condition and the model ship was constrained against any motion. Although the drift angle β was primarily set to 0°, 6°, and 12°, other settings were used in some experiments. All experimental results were processed using uncertainty analysis. The uncertainty analyzing method follows the ANSI/ASME Performance Test Code (PTC19.1-1985) and the AIAA Standard S-071-1995. Only a few error components were considered here and they were empirically chosen because they had a heavy weighting when used in the uncertainty calculation. The results of these towing tank experiments will contribute to the development of computational fluid dynamics (CFD) research in ship hydrodynamics.
