ALLOWING CONDENSATE RETURN TO THE BOILER FACT

Pressurised Deaerators | Spirax Sarco

The return of condensate from the plant will have a significant impact on boiler feedwater treatment - condensate is hot and already chemically treated, consequently as more condensate is returned, less feedwater treatment is required.

Condensing Boiler - Home

Condensing Boiler. This is a design of boiler which can have an increased efficiency over the more traditional boiler. The efficiency of a typical non-condensing boiler is around 75%, whereas with condensing boilers it can be over 87%. This increased efficiency is due to the extraction of heat from the otherwise wasted flue gases.

15/12/2010 · In addition, flue products contain large amounts of moisture. The flue gases must be hot enough to keep the vent system and boiler above the dew point, or moisture will condense on the vent system. This condensate is acid, and will cause corrosion. Flue gases for a gas-fired boiler should normally be in a range of 305 to 410 F above ambient.

Condensate pumps Boiler feed pumps Whats the difference?

Returning hot condensate to the boiler makes sense for several reasons. As more condensate is returned, less make-up water is required, saving fuel, makeup wa-ter, and chemicals and treatment costs. Less condensate discharged into a sewer system reduces disposal costs. Return of high purity condensate also reduces energy losses due to boiler blowdown. Significant fuel savings occur as most returned condensate …
