Tube Bundle Of Gas Cooler

Tube Bundle Of Gas Cooler

When the gas cooler finned tube bundle is in operation, the hot gas flows inside the tube and the cooling medium (e.g. air, water, etc.) flows outside the tube. Heat is transferred from the hot gas inside the tube through the tube wall to the fins, and then from the fins to the cooling medium outside the tube. Due to the presence of fins, the heat transfer area outside the tube is greatly increased, which enables the heat to be transferred more efficiently, thus realizing the cooling of the hot gas.

Advantages

Enhanced heat transfer: the presence of fins increases the heat transfer area significantly, and at the same time enhances the degree of turbulence of the fluid, reduces the thermal resistance, improves the heat transfer coefficient, and is able to more efficiently transfer the heat in the gas to the cooling medium, which significantly improves the cooling effect compared to the common shell and tube heat exchanger.

Save space: under the same heat transfer effect, finned tube bundle can adopt smaller tube diameter and more compact arrangement, thus reducing the overall volume and footprint of the equipment, especially suitable for places with limited space.

Adapt to a variety of working conditions: According to different gas properties, flow rates, temperatures and cooling media, suitable finned forms, pipe materials, tube arrangement, etc. can be selected to meet the requirements of a variety of complex working conditions.

Cost reduction: due to the improvement of heat transfer efficiency, in the case of achieving the same cooling effect, the required cooling medium flow rate may be reduced, thus reducing the cooling medium conveying power and operating costs; in addition, the compact structure also makes the equipment manufacturing materials and installation costs have been reduced.

Application areas

Petrochemical industry: It is used for the cooling of high temperature gases generated in various reaction processes, such as the cooling of cracking gas, synthesis gas, etc.; it is also used for the condensation of tower top vapors, the cooling of reflux oil and the cooling of oil at the bottom of the tower in the oil refinery.

Power industry: it can be used for condensation of power station turbine exhaust, and cooling of hot gases generated during the operation of generators, transformers and other equipment.

Refrigeration and air-conditioning industry: in large refrigeration systems, it is used to cool the high-temperature and high-pressure refrigerant gas discharged from the compressor, so that it can be condensed into a liquid for the subsequent throttling and evaporation process.

Metallurgical industry: It is used for cooling and purifying the high-temperature furnace gas generated in the process of metal smelting, recovering the heat energy therein, and at the same time reducing the thermal pollution to the environment.
