first embodiment
[0024]In the example shown in FIG. 1, the pumps 36 and 44 are operated at substantially the same flow rate so that the fluid is basically pumped in a cycle out of the SCV towards the heating tower, and then back from the heating tower back into the SCV. This is a However, one aspect of this system is that in most conditions the atmospheric heating tower will actually generate additional fluid in the form of water due to condensation that occurs in the tower. Therefore, some provision can be provided, such as an overflow discharge port 50 provided at a maximum desired fluid level of the basin 42. An overflow discharge port 52 can similarly be provided in the SCV 10.
[0025]The system described in FIG. 1 does have some possible disadvantages. For example, if the pump 44 fails, or if the conduits associated with pump 44 fail, it is possible that the re-supply of fluid back into the SCV 10 could be reduced or blocked entirely. In such a case, if the pump 36 continues to run, it is possib...
second embodiment
[0029]Turning now to FIG. 2, an improved fluid handling system is shown in which reference numerals in FIG. 2 depict like components as in FIG. 1. Continuing with FIG. 2, the SCV 10 is shown having a fluid 20 at an operating level L1. As discussed above, it is typically desirable to have L1 to be maintained in a range so that it is not too high such that it would swamp the burner, and not too low such that it would fail to add heat to the coils, which could lead to coil freezing or other undesirable situations.
[0030]Somewhat similar to the embodiment of FIG. 1, the heating tower 30 can be connected to the SCV 10 such that the heating tower 30 can supply warmed water to the SCV. In the case of such a supply, L1 will raise to a level and fluid will exit the SCV via a main outlet port 60, which may have a valve associated therewith. The exiting fluid flows from the main outlet port 60 into a holding weir 62. Should the valve associated with the port 60 be closed, or should the increase...
