Jan 04, 2022 · According to the manual that boiler should be using both tappings @ 2 1/2" piping with a 2 1/2" header. Even with that, being that oversized, it's only going to work "so good" on a 2 pipe system. Oversizing will cause pressure issues that will need to be controlled with a vaporstat unfortunately. 2014 Weil Mclain EG-40.

Proper treatment of boiler feedwater effectively protects against corrosion of feedwater heaters, economizers, and deaerators. The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper

Poor control of boiler water TDS, or contamination of boiler feedwater, will result in wet steam being discharged from the boiler. A number of problems are associated with this: Water droplets in steam pipes will tend to erode the inside of the pipe, and any other fittings,and valves, especially if velocities are high.

Figure 3.11.5(b) again shows the formation of steam at 10 bar g, but this time the boiler is fed with feedwater heated to 70°C by returning more condensate. The increased enthalpy contained in the feedwater means that the boiler now only has to add 489 kJ/kg of heat energy to bring it up to saturation temperature at 10 bar g.
