In many industrial objects there are emitted dusted gases of high temperature. Mostly it regards glass works, aluminum works, copper works as well as foundries and cement mills where gas temperatures may reach.The filtration process on filtrating bags must not take place under such conditions. In order to lower the temperature to a level acceptable for bags that is, we offer gas cooling systems. Temperature reduction is performed in two ways. The first one consists in distribution of cold atmospheric air and mixing both of the streams. Because of substantial increase in gas volumes, which must be filtrated at the next stage, it is not economic and it has been abandoned. The second gas cooling method takes place by means of a cooling system (pipe heat exchangers). It consists in cooling of hot gases without a need for stream of external air supplied into a stream of hot air. System operation is based on a convection process ( transfer of heat energy from hot gases into a cooling agent). A cooling agent may be a gas (the most frequently it is the atmospheric air ). Exchange of the heat energy takes place by means of exchange pipes’ walls. Since the cooling down air re-circulates it is possible to regulate its temperature before it reenters the exchanger.
