There are two methods of assessing boiler efficiency; 1. Input – output or direct method, and 2. Heat loss or indirect method. Direct Method for Calculating Boiler Efficiency. Direct method compares the energy gain of the working fluid (water and steam) to the energy content of the fuel.
Boiler Energy Saving Tips. To ensure that the boiler is operating efficiently, TLV recommends that you do the following: Set a standard maximum percentage of excess combustion air. Set suitable minimum levels of fuel quality and viscosity to improve the efficiency of fuel combustion.
Step 5. Calculate the combustion-air mass required to burn the 20 gallons of No. 6 fuel oil above. Since the air-fuel stoichiometric ratio is 14.4 pounds of air per pound of fuel, the boiler's burner would need 20 gallons x 7.95 lb/gal for No. 6 fuel oil, or 2,289 pounds of air to burn the oil.
New Energy Efficient Boiler Options. To improve boiler efficiency, it’s important to have the right model for your home - one that can cope with your needs and keep costs to a minimum: Combi(nation) boilers heat water on demand, making them incredibly cost-effective and energy efficient. However, as they don’t have a hot water storage cylinder, they are less effective for larger properties and families.
Energy Saving Tips. Don‘t leave the heating on low all day. According to the Energy Savings Trust, the idea it‘s somehow cheaper to leave the heating on low all day is a myth. You‘ll save energy, and therefore money, only by having the heating on when it‘s required.
Boiler Efficiency Calculators Boilers and steam systems consume large amounts of energy and may present an opportunity for significant cost savings. See the "About This Calculator" tab to get started on this savings.
Return Condensate to the Boiler. When steam transfers its heat in a manufacturing process, heat exchanger, or heating coil, it reverts to a liquid phase called condensate. An attractive method of improving your power plant’s energy efficiency is to increase the condensate return to the boiler.
