Protecting the Investment in Heat Recovery with Boiler Economizers
Abstract
Many people consider energy to be a crisis in remission
-- even with continuing high fuel costs.
Some voice concern over the long term security of
an investment in flue gas heat recovery equipment.
The concern generally involves the ability of an
economizer or air heater to continue to perform
efficiently without corrosion.
The recognized economic advantages of an economizer
result from its ability to convert heat
losses into sources of energy. One of the most
productive means of obtaining reduced energy costs
lies in the improvements of the efficiency of steam
generating boilers. Industrial and institutional
boilers operating at pressures of 75 psig or greater
are excellent applications.
The maximum gain that can be safely achieved is
governed by a number of technical and physical limitations.
Among these are considerations of the
economics, temperatures of the flue gas and water,
and the potential for corrosion. This paper will
discuss the economic and practical considerations
of an economizer installation.
