A: The specific heat of glycol solutions is lower than that of water. In order to transfer the same amount of heat, the lower heat capacity can be compensated for by increasing the flow rate of the heating plant. To calculate this, divide flow rate by the specific heat of the glycol solution at a given mix percentage and working tempera-ture.
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.

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.
Shell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated …
How to Calculate the Water Capacity of a Boiler System Measure each room of your house in cubic feet. Calculate the estimated BTU by noting down each room type, the amount of windows and type of windows in each room. Add the individual room calculations together. Divide the BTU by …
Oct 23, 2021 · However, if you have a boiler with a hot water storage cylinder/tank you will need to add an additional 3kW to power the tank. Therefore, if you had 10 radiators of average size and a tank, you would require an 18kW boiler. Why? 1.5kW x 10 radiators = 15kW. Plus 3kw for the tank. 15kW + 3kW = 18 kW. Boiler Size Calculator
Nov 24, 2016 · Boiler Efficiency:-Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilized to generate steam. There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.
A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW) hg = enthalpy steam (Btu/lb, kJ/kg) hf = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s)
Nov 02, 2017 · Many customers contact us online with the question of calculation of boiler capacity. they don't know how to calculate the boiler capacity they need. For example: It is common to express the output of fire tube and water tube steam boilers in Boiler Horsepower, MBTU or in Pounds of Steam delivered per hour.
May 20, 2015 · For a boiler rated 100 BHP: Use the formula above to convert boiler horsepower: BHP X 139 = sq ft EDR. 100×139=13900. When you calculate the amount of steam put out, you get 6.9 gpm of water as steam. Let's round that up to 7 gpm. Sizing the pump for …
