You Have Been Asked To Evaluate The Economic Implications Of Various Methods For Cooling Condenser Effluents From A 200 1 (132.68 KiB) Viewed 20 times

You have been asked to evaluate the economic implications of various methods for cooling condenser effluents from a 200-MW steamelectric plant. There are two basic types of cooling towers: wet and dry. Furthermore, heat may be removed from condenser water by (1) forcing (mechanically) air through the tower or (2) allowing heat transfer to occur by making use of natural draft. Consequently, there are four basic cooling tower designs that could be considered. Assuming that the cost of capital to the utility company is 12% per year, your job is to recommend the best alternative (i.e., the least expensive during the service life). Further, assume that each alternative is capable of satisfactorily removing waste heat from the condensers of a 200-MW power plant. What noneconomic factors can you identify that might also play a role in the decision-making process? Click the icon to view the alternatives description.

The AW of Wet Tower, Natural Draft is $ 1,706,130. (Round to the nearest dollar.)
