Abstract
Waste heat boilers or Heat Recovery Steam Generators (HRSGs) as they are often called
are used to recover energy from waste gas
streams in chemical plants, refineries, kilns, incineration systems and
cogeneration and combined cycle plants, to
mention a few applications. Depending on
several factors such as quantity of gas or
steam flow, cleanliness of gas, gas and steam pressure and space availability, they
may take various configurations as seen in
Fig 1 to 5. Consultants and engineers who
specify and evaluate HRSGs should be aware
that several factors influence the final
configuration of HRSGs. Some of these
factors are discussed below.
