Heat energy required to heat 700 gal can be calculated as follows: Heat Required = 5810 lbs x 1 BTU/lb ºF x (120 ºF – 55 ºF)

Get a Quote2012-5-31 · The annual energy savings (MM Btu/year) is due to added heat within the deaerator, reducing steam consumption due to increased feed water temperatures. Boiler blowdown contains a significant amount of energy which, without a heat recovery system, is wasted. There are several methods available to recover heat from boiler blow down.

Get a QuoteSo if the water in the pan on the stove is put in at 32°F, it will then require 180 BTU's to bring the water to boiling temperature, or 212°F. Now, no matter how hot the stove burner is, the water will get no hotter than 2120F. As this pound of water boils at 212°F, heat energy is being added to change it to steam.
