Abstract
Generating growth plans for power station dry ash dumps
having main and standby conveyor stacking systems is very
time consuming using manual analysis methods. This usually
prohibits investigating sufficient options or the routine
evaluation of operating variations. Not achieving or
changing any of the multitude ot geometric, physical or
production design. assumptions over the 50 year construction
life, can result in the dump growth deviating significantly
from the original plan. Out of phase or too rapid long term
growth situations can ensue, with costly modifications
sometimes needed to return to acceptable growth plans or
provide additional capacity.
It was postulated that a parametrically driven computer
model would facilitate rapid and cost effective dump growth
evaluation. This dissertation documents the development of
a prototype, spreadsheet-based, parametric modeling program
for automating the production of dry ash dump growth plans.
The system showed that sensitivity, optimisation and routine
evaluation exercises now become practicable.
