natural gas boiler supply calculation formula

Proper sizing of Boiler Feedwater System

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. For example, if you have a 500 HP boiler the calculation will be as

Is it cheaper to heat my home with gas or electricity

Jun 07, 2018 · If you take the heating bill part of this (approx. £950) with an 80% efficient gas boiler and a unit of gas is 4p / kWh it would suggest using 23650kWh of gas. If you used an electric heating system operating at efficiency it would require 18920 kWh of electricity which indeed is less in pure numbers terms, but at 11p/kWh it would

CH104: Chapter 7 Solutions Chemistry

7.1 Introduction: Recall from Chapter 1 that solutions are defined as homogeneous mixtures that are mixed so thoroughly that neither component can be observed independently of the other. Solutions are all around us. Air, for example, is a solution. If you live near a lake, a river, or an ocean, that body of water is not pure H 2 O but most probably a solution.

Implied heat rate: A calculation of the day-ahead electric price divided by the day-ahead natural gas price. Implied heat rate is also known as the break-even natural gas market heat rate, because only a natural gas generator with an operating heat rate (measure of unit efficiency) below the implied heat rate value can make money by

Why is important the oxygen dissolved in water

However, high DO levels speed up corrosion in water pipes. For this reason, industries use water with the least possible amount of dissolved oxygen. Water used in very low pressure boilers have no more than 2.0 ppm of DO, but most boiler plant operators try to keep oxygen levels to 0.007 ppm or less.
