Abstract
In this study, integration of
appropriate renewable methods are going to be applied on conventional coal
fired steam power plant which has 660 MW full load capacity and including 4
Turbines (1 HP,1 IP and 2 LP), one Benson type boiler and having multi pre
heater stages for each unit. Steam parameters are 177 Bar and 541 o C
super-heater section and 50 bar 539 o C for re-heater section. Primary fuel is
coal except for startup and shut down operations. It is aimed by retrofitting
some renewable energy methods on existing power plant, thus eliminating
conventional type power plants adverse effects on thermodynamically,
environmental and economic issues.
One
of the most important issue of conventional steam power plant operation is
waste heat recovery management. A widespread techniques has been developed on
this topic. It's possible to handle low grade heat by considering thermodynamic
and environmental facts and also dealing with restrictions and opportunities
after fulfilled feasibility study. In this study, it is being proposed waste
heat recovery by combining Organic-Rankine Cycle (ORC) with steam-Rankine cycle
at available section. Brief summary of operation is ORC takes place after
regenerative air preheater section and the target is to utilize waste heat of
flue gas either via district heating or power generation up to few MW values.
Depending upon the calculation and results additional modifications can further
be needed as well.
