Modeling Of A Combined Cycle Mhd/Steam Power Plant, Edward H. Kiessling Iii Aug 1984

Modeling Of A Combined Cycle Mhd/Steam Power Plant, Edward H. Kiessling Iii

Masters Theses

The objective of this effort was to develop an improved process model of a prototype MHD/steam central station power plant. This model was designed to perform a first law thermodynamic analysis for steady state plant operation. An existing MHD topping cycle model was modified to provide predictions of mass flows and energy requirements associated with topping cycle equipment for coal processing and oxidant preparation. This topping cycle is characterized by full slag carryover to the heat and seed recovery system. PRESTO II, a program for analyzing the performance of regenerative, superheated steam-turbine cycles, was added to the existing model ...


Performance Of A Ground-Coupled Heat Pump During A Cooling Season, Steven D. Wix Jun 1984

Performance Of A Ground-Coupled Heat Pump During A Cooling Season, Steven D. Wix

Masters Theses

A ground-coupled heat pump system was installed in TECH House I at the Tennessee Energy Conservation in Housing site located on the University of Tennessee campus. The performance of the heat pump system was evaluated for the cooling season of 1983. Data on system energy flows, power consumption, house temperatures, soil temperatures and weather conditions were gathered on an hourly basis for the entire cooling season. Weekly coefficients of performance, soil thermal conductivitys, and a seasonal performance factor were calculated from experimental data.

The performance was found to be poor when compared to a conventional air-to-air heat pump system. The ...


A Wear Minimization Design Investigation Of Feedline Splitters, Turning Sections, And Feed Nozzles Of A Pneumatic Conveyed Solids System, Warren R. Gilbert Jr. Jun 1984

A Wear Minimization Design Investigation Of Feedline Splitters, Turning Sections, And Feed Nozzles Of A Pneumatic Conveyed Solids System, Warren R. Gilbert Jr.

Masters Theses

The adverse effects of wear has continually plagued the operation of the TVA 20 MW Atmospheric Fluidized Bed Combustion Pilot Plant. Wear has caused serious problems in all aspects of the pneumatically fed below-bed coal feed system. This has given rise to the development of high wear resistant designs of feedline splitters, turning sections, and feed nozzles.

Wear testing of PVC feedline system components was conducted at The University of Tennessee to determine the wear characteristics of different designs. PVC was chosen for the feedline system component material to accelerate the wear testing results. A series of similar tests were ...
