Transform the saturated hot water tower problem?
Thread Content
Was it said at the Guiyang conference some time ago that canceling saturated hot water towers was a mistake? But now, saturated hot water towers have all been eliminated; some say it’s not a big deal, while others claim it’s mainly due to corrosion issues How is the transformation of the saturated hot water tower in your plant taken into account?
Which one was canceled and what was used as a replacement?
These days, full low-variation systems at 2.1 MPa basically don’t have saturated hot water towers at all
A non-saturated hot water tower process can be used, and there is no problem with that; however, the heat recovery efficiency is lower compared to that of a saturated hot water tower, and steam consumption is higher.
There are now many processes that do not use saturated hot water towers, but they are indeed less effective in terms of heat recovery compared to those with saturated hot water towers. Moreover, corrosion in saturated hot water systems is truly a troublesome issue
While we emphasize the use of a hot water saturation tower, this actually reduces the load associated with water addition. So how should we understand the deoxygenation process in the deaerator? That process also requires steam, so we can’t make generalizations. How can this loss be compensated for? The actual savings turn into savings from the recovery of heat losses in the pipes; this amount is not significant. How should this be understood? Actually, this is quite complex to consider, I think
There are now conversion processes for both saturated and unsaturated hot water towers, each with its own advantages and disadvantages; the main issue related to corrosion is the pH level.
