Product Description
Working principle of a flue-gases cooler is the same as in the
above-described equipment, but the aim in this case is to cool a
primary fluid, not to get a thermal profit by heating a secondary
fluid.
These equipment are usually installed as the previous step to a
flue-gases cleaning, to avoid the gases from reaching the cleaning
systems at too high temperatures. This means an alternative to the
dilution with air, which would imply an over-sizing of the
mentioned systems
Details
Before designing this kind of equipment, it is necessary to know
the nature of the gases to be cooled and their dust content. The
purpose of all that is to design an equipment free of important
fouling which would force to make cleaning works more frequently
than wanted.
We must have in mind as well the availability to detach the dust
from the gaseous stream containing it in all those areas where
there is a bend or some enlarging in the pass section, which forces
to include in the design some systems for dust collection and
removal, to allow the correct heat exchange.
Functions
1. Absorb the heat of low-temperature flue gas, reduce the smoke
discharge temperature, reduce smoke loss, and save fuel.
2. Since the feed water is heated in the economizer before entering
the steam drum, the heat absorption of the feed water on the
heating surface is reduced, and the economizer can be used to
replace part of the evaporation heating surface with higher cost.
3. feed water temperature increased, into the drum will reduce the
wall temperature difference, thermal stress corresponding to
reduce, extend the service life of the drum.
Design principle
When the designer's choice is the multi-cyclone collector,or the
electrostatic precipitator,or a different type constructed of
metals or ther low temperature materials,it becomes necessary to
add a gas-cooling device.This is done to assure that he entering
flue gases are with in the temperature range of 600 to 700F,with no
possibility of even flashes of higher temperatures.
The exit temperature depends upon the materials used downstream
from the cooling chamber.Since , however , experience and
economical evaluations justifying the use of the high temperature
alloys are not generally available this paper is based upon the
exit temperatures stated above.
The two agents commonly used as cooling materials are air and
water.Both have advantages and disadvantages.Generally,a
combination of the two is found most acceptable.However,they must
first be considered separately,so that the characteristics of each
may be properly evaluated.
