How Much Home Heating Oil Will I Use This Winter | 24/7

The most common question among people who use home heating oil is how much oil I will need this winter. It’s no wonder, as heating oil is delivered at exact amounts (like coal and wood, and unlike electricity of natural gas), so it’s best to estimate the

Optimal Combustion Process – Fuels and Excess Air

Power plant boilers normally run about 10 to 20 percent excess air. Natural gas-fired boilers may run as low as 5 percent excess air. Pulverized coal-fired boilers may run with 20 percent excess air. Gas turbines runs very lean with up to 300 percent exce

5 – 20% for fuel oil; 15 – 60% for coal; Carbon dioxide – CO 2 – is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide – CO 2 – after combustion is approxim

Boiler Combustion | CleanBoiler.org

When firing fuel oils, NOx formed by fuel-bound nitrogen can account for 20-50% of the total NOx level. One method to reduce NOx levels from boilers firing distillate oils is through the use of low nitrogen fuel oil. Low nitrogen oils can contain up to 15

Understanding Residential Boiler Efficiency Ratings | Weil-McLain

The minimum AFUE rating requirements for boilers varies based on the type of fuel and the heating medium used. As of September 1, 2012, all boilers manufactured have the following minimum AFUE ratings: 82% for a gas-fired hot water boiler, 80% for a gas-f

It’s a highly efficient heating fuel, so you get a good return for each unit of energy; As long as you keep an eye on the amount of oil in your tank and order a redelivery in good time, you’ll have a constant supply of fuel – in fact some systems will aut

Turndown ratio

Turndown ratio refers to the width of the operational range of a device, and is defined as the ratio of the maximum capacity to minimum capacity. For example, a device with a maximum output of 10 units and a minimum output of 2 units has a turndown ratio

Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high-efficiency versions of all types of furnaces and boilers are currently available. To learn more about furnaces, boilers and other types of ho

Annual fuel utilization efficiency

The annual fuel utilization efficiency (AFUE; pronounced ‘A’-‘Few’ or ‘A’-‘F’-‘U’-‘E’) is a thermal efficiency measure of space-heating furnaces and boilers. The AFUE differs from the true ‘thermal efficiency’ in that it is not a steady-state, peak measur
