Which Option Is Best? a. The conventional economizer
Based on a number of general assessments b. The indirect-contact condensing heat ex-
considering all facts involved in economic bene- changer
fits, engineering criteria, installing and operating c. Direct contact flue gas condensation heat re-
waste heat recovery systems; three primary sys- covery
tems have evolved as being very good prospects
for waste heat recovery. The waste heat recovery Table 12.5, summarizes the merits and lim-
systems which showed the most promise and ap- itations of various heat recovery alternatives.
