Boiler Efficiency - an overview | ScienceDirect Topics

The amount of energy used in the process to remove water is about half of what it would take to evaporate the same amount of water in a coal boiler during combustion. A 750 000 t/year K- Fuel processing plant has been built in Gillette (Wyoming, USA).

Characteristics of boiler feedwater - Lenntech

The purity requirements for any feed-water depend on how much feed water is used as well as what the particular boiler design (pressure, heat transfer rate, etc.) can tolerate. Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while

Boiler Feed Water Flow Rate Requirements Chart | Nalco PTS

Dec 29, 2006 · This chart relates boiler horse power to the flow rate in gallons per minute and pounds per hour. In this case, we need a demineralizer or softener rated for a maximum flow rate of 28 gpm. It will be less depending upon how much condensate is returned. The next part of this question is what water quality is needed for the application.

Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

How much water do you use? — Heating Help: The Wall

In most cases ten minutes of water should be readily available for your boiler. One boiler horsepower = 34.5 lbs/hr of steam (or water) from and at 212o F. We also know that one-gallon of water weighs 8.37 lbs. To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in gallons.

of water in one hour is rated at 10,000 pounds per hour. To further confuse the issue, we sometimes speak of Boiler Horse Power (BHP) when we refer to a boilers capacity. One BHP is equal to 34.5 pounds per hour of steam, so 10,000 pounds per hour of steam is the same as 289.9 BHP. Remember, we used only 180 BTUs of energy to bring a pound
