Energy Required for Water Heating | EGEE 102: Energy

2020-3-5 · To calculate the heat required, determine the variables: m = mass of water heated = 700 gallons = 5810 lbs C p is the heat capacity of water = 1 BTU/lb ºF (given) ΔT = temperature difference = 120 ºF – 55 ºF. 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)

Recover Heat from Boiler Blowdown Water - Go Solar

2012-5-31 · 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.

How many BTUs does it take to boil one pound of

So 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.
