Steam, produced in the boiler at 10 bar g, is to be used as the heating agent. If the 'From and At' rating of the boiler plant is 10 tonne/h, determine the flowrate of steam required to heat the deaerator. Before any calculations can be made to estimate the size of the deaerator, it is important to know the maximum likely feedwater requirement.Learn More
Mar 18, 2014 · A detailed heat loss should be provided before a new boiler is installed. * Heating multipliers (H.M.) BTU/Hr based on 60 degrees F Temperature Difference (T.D.) Procedure Measure the total length of all outside walls for the house. Calculate gross wall area by multiplying total length by height of the walls. Measure the window and door area.Learn More
Oil-fired steam. 82% AFUE. Oil-fired hot water boilers. 84% AFUE. The higher the AFUE rating, the more efficient the heating system, and the less energy needed to heat your home. For example, a new, high-efficiency furnace with a 94 percent efficiency rating provides 94 cents worth of heat from every energy dollar.Learn More
The AFUE rating for an all-electric furnace or boiler is between 95% and . The lower values are for units installed outdoors because they have greater jacket heat loss. However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric furnaces or boilers an uneconomic choice.Learn More

Slant Fin Corporation is the first baseboard and boiler company to come out with a heat loss calculator app for iPad, iPhone, and Android devices. We would love for you to download the free app and give it a try. This user friendly app can be used as a heat loss calculator as well as a product selection guide.Learn More
Moisture free fuel should be fed to the boiler so that no amount of heat is lost in removing the moisture from fuel and all the heat can be efficiently used to convert water to steam. Most heat losses are due to the high temperature of dry flue gases leaving the boiler. Boiler maintenance should be done regularly and be removing the scale deposited on the heat transfer tubes …Learn More
