Detailed Description
The present utility model will be further described in detail with reference to the following examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent.
Referring to fig. 1-3, the present utility model proposes a heat exchanger 100 for a gas turbine. The gas turbine typically comprises an inlet chamber C, via which gas enters the gas turbine. In the intake chamber, the flow direction of intake air is as indicated by an arrow A1 in fig. 1. The heat exchanger 100 is provided inside the intake chamber C for heating or preheating the intake air in the intake chamber C.
As best shown in fig. 1, the heat exchanger 100 may comprise a heat exchanger housing 1 and at least one heat exchange line 2. Each heat exchange line 2 may include an inlet 21, an outlet 22, and a heat exchange tube 23 located between the inlet 21 and the outlet 22. The heat exchange tube 23 may be provided inside the heat exchanger housing 1. Hot water from the hot water supply bus can enter the heat exchange tube 2 via inlet 21, flow through the heat exchange tube 23 and exit the heat exchange tube 2 via outlet 22. Accordingly, the heat of the hot water from the hot water supply bus can be dissipated through the heat exchange tube 23 to exchange heat with the intake air in the intake chamber C, thereby achieving heating or preheating of the intake air.
As best shown in fig. 2 and 3, the heat exchange tube 23 may include a tube body 231 and at least one fin 232. The tube body 231 may have a hollow cylindrical shape. The fins 232 may be circumferentially disposed on the exterior of the tube body 231. By such an arrangement, the heat transfer area can be significantly increased by the at least one fin 232 circumferentially disposed on the outside of the tube body 231, thereby enhancing the heat transfer effect.
As best shown in fig. 3, in an advantageous embodiment, the tab 232 may have a circular ring shape. Such an arrangement can promote more uniform heat transfer.
As best shown in fig. 2, the heat exchange tube 23 may include a plurality of fins 232, the plurality of fins 232 being equally spaced from each other in the extending direction of the tube body 231. Such an arrangement can also promote more uniform heat transfer. In the embodiment shown in fig. 2, four fins 232 are schematically shown, but the number of fins 232 is not limited thereto and may be selected according to actual needs.
The heat exchanging tube 23 may be made of stainless steel, in other words, the heat exchanging tube 23 may be a stainless steel tube.
In an advantageous embodiment, the heat exchange tube 23 may be made of aluminum, in other words, the heat exchange tube 23 may be an aluminum tube. The use of aluminum for the heat exchange tubes 23 can reduce the weight of the heat exchanger 23 by more than 40% compared to the case where the heat exchange tubes are manufactured from, for example, stainless steel as is common. Also hereby, the on-site retrofit time can be reduced by 10 to 15 days, since the heat exchanger tubes 23 of significantly reduced weight generally do not need to be retrofitted on site to the air intake house 3 and its foundation, and can thus be used in all existing gas turbines without the need to reinforce the air intake house.
As shown in fig. 1, each heat exchange line 2 may further include an inlet pump 24 located between the inlet 21 and the heat exchange tube 23, and a water circulation valve 25 located between the heat exchange tube 23 and the outlet 22. This allows independent control of the water intake to each heat exchange line 2, and improves the temperature uniformity of the intake air.
In the embodiment shown in fig. 1, the heat exchanger 100 may comprise a plurality of heat exchange lines 2 arranged in parallel. The inlets 21 of the plurality of heat exchange lines 2 branch from the hot water supply bus, and the outlets 22 of the plurality of heat exchange lines 2 converge back to the hot water supply bus, wherein an arrow B1 in fig. 1 schematically shows the inlet direction of hot water from the hot water supply bus, and an arrow B2 in fig. 1 schematically shows the outlet direction of cold water after heat exchange.
As exemplarily illustrated in fig. 1, the heat exchanger 100 may include four heat exchange lines 2 arranged in parallel, but the number of the heat exchange lines 2 is not limited thereto and may be selected according to actual needs.
Preferably, each heat exchange tube 23 may extend in a horizontal direction (i.e., parallel to the flow direction of the intake air), and the plurality of heat exchange tubes 23 may be arranged side by side in a vertical direction (i.e., perpendicular to the flow direction of the intake air). By such an arrangement, the temperature uniformity of the intake air can also be improved.
Furthermore, as shown in fig. 1, the inlet pump 24 and the water circulation valve 25 may be provided outside the heat exchanger housing 1.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the utility model.
