pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

Is Copper a Problem in Boiler Feedwater? - Finishing

2001. A. Doug - Yes copper in boiler feedwater can cause problems. The boiler chemicals that are used are there to help form a magnetite coating on the boiler tubes and protect them from corrosion. Magnetite is black oxide and most black oxide chemistries have rectifiers in them to help control metals that otherwise would inhibit the black oxide conversion.

3/4" vs. 1/2" copper tubing for heat exhangers? | Hearth

3/4" vs. 1/2" copper tubing for heat exhangers? Posted By rfactor, Aug 2, 2009 at 11:53 PM. If you manage a 20* temp difference at those flow rates you can transfer 15,000 btu, 40,000 btu and 80,000btu respectively. ErgoMax and ThermoMax do this with 3 copper coils inside the "boiler water" tank. With enough surface area, and correct

Thermal Design of Heat Exchangers - Energiteknik | KTH

Heat power depends on the heat transfer area (A), temperature difference (t1-t2), thermal conductivity of material (λ) and the thickness of separating wall (s). The thermal conductivity is a property of the material; metals conduct well heat whereas gases not. An example of thermal conductivities in various materials is shown in table 1.

PEX vs Copper for Domestic Plumbing Systems. Why is PEX

Why most People prefex PEX Tubing over Copper - there is a less risk of leaks with PEX Tubing. PEX doesn't degrade like copper, higher PSI rating freezing pipes will still burst, but PEX will be able to handle more freezing water than copper. PEX Tubing is much more resistant to freeze-breakage than copper or rigid plastic pipe.
