Are these statements about the regenerative heat exchangerstrue?
Statement 1: Regenerators are commonly used in gas/gas heat recovery applications.
Statement 2: Regenerative heat exchangers are also known as capacitive heat exchangers.
a) True, False
b) True, True
c) False, True
d) False, False

Answer: b
Explanation: Regenerative heat exchangers are also known as capacitive heat exchangers. The flow path consists of the matrix where heat from the hot fluid is captured in the matrix and then it is released to the cold fluid. Regenerators are commonly used in gas/gas heat recovery applications mainly in power stations. Static and dynamic are the two types of regenerators.
