The gas coolers are basically devices that are used for controlling environmental pollution when dirty hot emissions from the industrial processes need to be cooled for the purpose of entry into the pollution control equipment. These coolers generally deploy ambient air for their cooling medium even though the units that are water cooled are also furnished. One of the primary considerations that are made during the designing of the gas coolers is necessity for keeping the heat transfer surfaces very clean. The arrangements are selected largely for allowing continuing in-situ cleaning by using chain or shot cleaning systems and soot blowers. If you want to know more about the gas coolers, you need to bear some important details in mind.
Vital Details about Gas Coolers
Features of the Gas Coolers
One of the most important things about the gas coolers which you should know is that these coolers are designed with hot waste gas that flows down in a vertical manner over the outer parts of the horizontal tubes while at the same time cooling the air which passes inside these tubes. A very large volume of the cooling air is then provided by a number of panel fans or vane axial fans that are mounted at one side of the gas cooler. The entire cooling system is usually supplied including outer shells, ducts, tube bundles, cooling fans, structural supports, hoppers, walkaways etc. Some of the other cooling orientations and arrangements may also be available including designs which have the passing of hot waste gas inside the tubes.
Applications that Use Gas Coolers
There are several important applications that use the gas coolers.
Popular examples are the electric arc furnaces, the annealing furnaces, the smelting furnaces, the roasting furnaces, the glass melting furnaces and the cement kilns. They are also deployed by steel furnaces, aluminum furnaces, ferroalloy furnaces, refractory kilns and ceramic kilns.
Expensive to Buy and Maintain Gas Coolers
The gas coolers are extremely expensive devices. They are used for industrial purposes and therefore they cost a lot of money. The prices of the gas coolers often run into hundreds of thousands of dollars. The gas coolers are also very expensive to maintain. If these devices from any kind of damage then a substantial amount of money will have to be spent on their repair. The maintenance of the gas coolers may turn out to be more expensive than their cost price as maintenance is something that might be required frequently for efficient functioning of the coolers.
Environment Friendly in Nature
The gas coolers are not likely to risk the environment in any way. Their purpose is to prevent the spread of toxic gaseous air into the atmosphere and consequently they help in the maintenance of a clean and healthy atmosphere. They are very effective tools for the control of environmental pollution.
Thus, the gas coolers are characterized by several important benefits. However, they are expensive to buy and are a very heavy investment made by the Steel plants, manufacturers of buildings etc.
