Effect of Clearance Leakage Loss on Economics of Steam Turbine

2009 International Conference on Energy and Environment Technology, 2009
The leakage loss is very important to the economics of steam turbine. But in the practical operation process, the radial clearance often is enlarged in steam turbine flow passage. Aimed at this phenomenon, the influences of clearance leakage on the relative internal efficiency and the power of steam turbine are studied in this paper.

Leakage Targets and Socio‐Economic Efficiency

Water and Environment Journal, 2001
AbstractDuring the last few years, the introduction of mandatory leakage targets for UK water companies has had the positive effect of reducing levels of leakage, while requiring the companies to operate at an economic level of leakage. Unfortunately, the determination of company‐specific economic levels of leakage have been a source of disagreement ...

Economic Optimization of Distribution Leakage Control

Water and Environment Journal, 1988
ABSTRACTEvry WATER DISTRIBUTION system has an economic optimum level of leakage. To maintain that optimum level of leakage there is a corresponding optimum level of leakage control activity.Despite much work on this subject, particularly in recent years with publication of DoE Report No. 261, many undertakers remain unclear about their economic optimum

Efficiency of Carbon storage with leakage: Physical and economical approaches

Energy, 2007
In this paper, two methods are proposed to assess the efficiency of carbon capture and storage (CCS) involving back-leakage of CO2 from geological storage reservoirs to the atmosphere. The first method is a physical approach based on radiative forcing.
