Large storage tank for 95-degree hot water
Thread Content
The company is currently installing a hot water storage tank with a capacity of 10,000 liters. I would like to ask: the operating temperature for the hot water is 95 degrees, and the client has specified that it should operate at atmospheric pressure. I would like to ask the seniors: what is a suitable value for the design pressure of this storage tank? Is it more appropriate to install a vent at the top under normal pressure, or is it better to use a breather valve with a slight internal pressure? Since the project is located in the north, hot steam will continuously emerge if a vent is installed at the top. Are there any good solutions for this? Also, should the issue of the vent freezing be taken into consideration?
No one has replied. I also want to know what should be done; it seems that a breathing valve should be installed on the tank, so that it opens automatically when a slight negative pressure is detected； The vent pipe is connected to a subsequent system (such as a water tank, absorption tower, etc.)
