Complementary Equipment

Boiler house auxiliary equipment covers supporting devices that affect boiler feedwater handling, condensate management, steam venting, blowdown cooling, and heat recovery. Selection is based on operating pressure, temperature, feedwater or condensate flow rate, piping configuration, compatibility with the feed tank, and drainage or venting requirements.

This category includes ADCA BFT boiler feed tanks, EH vent heads, FCD flash steam condensing heads, HCC cooling and mixing vessels, and LIPO condensate lifting units. BFT tanks provide intermediate storage for feedwater and returned condensate. They are manufactured in carbon steel or stainless steel, with EN or ASME flanged connections and ISO or NPT threaded connections. Maximum allowable pressure is 0.5 bar and maximum temperature is 120 °C.

EH vent heads are installed at vent or discharge points to separate entrained liquid from discharged steam. Available sizes range from DN 25 to DN 250, with carbon steel, zinc-plated steel, or stainless steel construction, and EN PN16 or ASME Class 150 flanged connections. FCD units are applied where flash steam or secondary steam must be condensed before drain disposal or return to the system. They are manufactured in stainless steel, with ISO 7 Rp threaded or EN/ASME flanged connections, and are rated for 0.5 bar and 120 °C.

HCC vessels are used for mixing and cooling high-temperature discharge streams, condensate, or boiler blowdown prior to safe discharge to drain. Reported connection options include EN PN16/PN40 and ASME Class 150/300 flanges, with maximum operating conditions up to 40 bar and 300 °C. LIPO units are used for condensate lifting where available differential pressure or plant layout does not permit gravity return. They are available from DN 15 to DN 100, with maximum operating pressure up to 18 bar and temperature up to 250 °C.
