A steam generation system at a biomassfueled power plant uses an electrostatic precipitator (ESP) to clean its gaseous effluents

. The power plant has consistently made use of the same type of ESP over the past several years. The installed cost of a new ESP has been relatively constant at $80,000. Records of operation and maintenance expenses indicate the following average expenses per year as a function of the age of the ESP. The MVs of the ESP are also reasonably well known as a function of age. Determine the best time to replace the ESP if the MARR
is 15% per year

A steam generation system at a biomass-fueled power plant uses an electrostatic precipitator (ESP) to clean its gaseous effluents. the best time to replace the ESP is mathematically given as

EUAC3= 46377.48

<h3>What is the best time to replace the ESP if the MARR is 15% per year?</h3>

Generally, the equation for the EUAC for the yrs of operation is mathematically given as

For Year 1

EUAC1 = 85000 * (A/P,9%,1) + 25000 - 63000 * (A/F,9%,1)

EUAC1 = 54650

Solving till year 5

EUAC2= 46525.60

EUAC3= 46377.48

EUAC4= 48730.91

EUAC5= 50730.79

In conclusion, the best time to replace the ESP if the MARR is 15% per year will be at the EUAC3= 46377.48 since EUAC is the lowest at that year.
