why return condensate to the boiler operation

Condensate pump DIYnot Forums

Feb 04, 2011The pump is to get the condensate from the boiler into a drain. Liquids run downwards all by themselves. If the route for the condensate pipe needs to go uphill at any stage then you need a pump. Using a pump allows a pipe routing that is easier and causes less building work than finding a constantly downhill route for the pipe to get to a drain.

Effectively what this means is that the lower the return water temperatures, the greater the boiler efficiency. Figure 3 This image shows high-efficiency condensing boilers with condensate neutralisers installed in the pipes that connect the boiler drains to the point of discharge.

Why You Need to Insulate Steam Condensate Return Line

The condensate and hot water return lines also need to be insulated. Why you ask? Reasons to Insulate Condensate Return Lines 1. Increase Efficiency Insulating the condensate or hot water return lines reduces heat loss from the water returning to the boiler. The hotter the water returning to the boiler is, the quicker it is to convert back to

Prevention of corrosion in steam boiler systems

This acidic condensate will attack the return lines causing a characteristic trough at the bottom of the return line. The corrosion products will in turn be returned to the feedwater and can result in iron deposits in the feedwater tank as well as the boiler.

Getting the Most Out of Your Commercial Condensing Boiler

Commercial Condensing Boiler Operation. By allowing the temperature of the return water to go below roughly 130 F this causes moisture to condense out of the flue gas. That moisture is vapor before it condenses and by turning a vapor into a liquid, useful energy (heat) is given up in the process.
