Title: Concept and preliminary design of double tubesheet connector region for design and steady-state conditions. [LMFBR]

Abstract

In this analysis the structural integrity of the double tubesheet connector for the LMFBR demonstration plant steam generator is investigated for design and steady state conditions. Although the evaporator and superheater are to be interchangeable, only the steam outlet end of the evaporator is investigated. This was selected because the mean temperature differences between the tubesheets, tubes and connector are largest here at steady state, thus yielding the highest thermal loads. Combined with the thermal loads are superheater pressures in order to also use the highest mechanical loads. Although this is a conservative approach for the evaporator, the superheater must be analyzed separately at a later date in order to assure interchangeability. Evaluation of the results is based upon ASME Code Case 1331-8.

    A sophisticated, computer-based, steady-state simulation model has been developed and used to investigate the off-design and phased-construction performance of integrated coal-gasification combined cycle (IGCC) power plants. The ASPEN process simulator was used as the basic framework for the complete systems model; enhanced FORTRAN models were developed for critical components in the plant where the standard ASPEN models were felt to be inadequate. The effects of ambient temperature and part-load operation on a commercial-scale IGCC plant were investigated and strategies to mitigate the off-design performance penalties were examined. Increased ambient temperatures were found to considerably reduce the plant output; this effectmore » could be mitigated through the use of supplemental firing at the expense of increasing the heat rate. Part-load performance could be considerably improved by shutting down one or more gas turbines to enable the other gas turbine trains to operate nearer to full load. The performance of various initial and final plant configurations for the phased-construction operation of IGCC power plants was examined in detail. It was found that if the plant were optimized for operation as a natural-gas-fired combined cycle plant, several critical components would be undersized when the plant was converted to IGCC operation. Similarly, some components would be oversized if the plant were designed for IGCC operation but operated as a combined cycle plant. Operating strategies and reconstruction techniques to mitigate these performance penalties were also investigated. 19 refs., 31 figs., 19 tabs.« less

  • The purpose of this guidance is to describe and compare two methods that can be used to calculate stream design flows for any pollutant or effluent for which a two-number water quality criterion (WQC) for the protection of aquatic life is available. The two methods described are: the hydrologically-based design flow method recommended for interim use in the Technical Support Document for Water Quality-based Toxics Control; and a biologically-based design flow method that was developed by the Office of Research and Development of the U.S. EPA.

    Water Quality Standards for many pollutants are written as a function of ambient environmental conditions, such as temperature, pH or hardness. The document provides guidance on selecting values for these parameters when allocating wasteload dischargers among several dischargers using steady-state water quality models.
