Air Cooled Steel Finned Tube Bundle Heat Exchanger for boilers
Air heat exchangeris a kind of heat exchanger that is used to cool or heat forcibly flowing air with water, glycol solution, steam or heat conduction oil as the medium.Different models of heat exchanger should be selected according to the actual working conditions.
——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.
——Kind of fluid.
——Maintenance and cleaning works.
——Connection of the equipment with the rest of the plant.
——Depending on the above mentioned factors, different technical solutions may be applied which will go
through the adoption of an arrangement:
——Modular (with only one or many fans).
One or more steps.
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.
