Steam System Balancing for Multifamily Existing Buildings

The larger the steam chest, the drier the steam, and the lower the waterline, the larger the steam chest, so lowering the waterline helps make dry steam. If a steel boiler doesn't have a tankless coil, the casting mark on the water feeder/primary low water cutoff (LWCO) should be about ½" above the top-of-tubes.

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived
