Higher Calorific Values for some common fuels a coke, oil, wood, hydrogen and many more The calorific value or heat of combustion or heating value of a sample of fuel is defined as the amount of heat evolved when a unit weight ( or volume in the case of a sample of gaseous fuels ) of the fuel is completely burnt and the products of combustion
Firewood BTU Chart. Okay, now that we've determined the difference between seasoned vs green or wet firewood and the difference between a full cord vs a face cord, let's look at the amount of BTUs generated from a specific firewood type. The following chart describes the BTUs generated from different species of popular firewood.
Fuel heating value is one of the most fundamental values in boiler calculations. Heating value is used as the basis for energy balances. Similarly in boiler dimensioning engineering, constants like the furnace heat load and heart heat release rate (HHRR) are specified using the fuel heating value.

Units for comparing energy. Some popular units for comparing energy include British thermal units (Btu), barrels of oil equivalent, metric tons of oil equivalent, metric tons of coal equivalent, and terajoules.. In the United States, Btu, a measure of heat energy, is the most common unit for comparing energy sources or fuels.
Energy Density — Calorific Value — of Boiler Fuels. Fuel density is the energy a gallon or liter or pound or ton of fuel puts out. It is generally measured in million Btu per gallon or ton of fuel. Energy — or "Fuel" — Density of Distillate Diesel and Residual Fuel Oil.
 For solid fuels, the heating values in units of Btu/lb are converted from the heating values in units of Btu/ton.  Coal characteristics assumed by GREET for electric power production.

The fuels consumed in boilers in large quantities are nat- ural gas, distillate oil, residual oil, and coal. Additional energy is derived from the burning of waste fuels such as bark, bagasse, liquid hydrocarbon waste materials, etc. These fuels contribute only a small percentage to energy needs.

Not all the energy from the fuel is released, and not all the heat is available to heat the place. For example, if a furnace’s efficiency is, say, 50 percent, then twice as much fuel would be needed to heat a home. Looking again at the table on the previous screen, we saw that the heating value of fuel oil is given as 140,000 BTUs.

The calorific value of LFG can be defined as the amount of heat produced on combusting a unit volume of gas and can be expressed in kcal/m3, kJ/m 3, or BTU/ft 3. Calorific value depends directly on the methane content of LFG, i.e., the higher the methane content, the greater the calorific value. As defined in previous sections, the composition ...
Boilers 146 Fuel: Heat Values By James McDonald, PE, CWT Originally Published: CSTN February 2005 T ypical gross heating values of some common fuels (based upon approximately 80% fuel to steam efficiency) are listed below: x Petroleum coke = 11,500 to 15,000 BTU/lb x Anthracite coal | 14,000 BTU/lb
The average gross heating value of natural gas is approximately 1,020 British thermal units per standard cubic foot (Btu/scf), usually varying from 950 to 1,050 Btu/scf. Emission factors are based on an average natural gas higher heating value of 1,020 Btu/scf.
Heating Value by Unit Chart. The following is a listing of heating value per unit for common heating fuels. The column of equivalent units is based around the heating value of 1 ton of wood chips. For example, to get the same heating value (BTU's) as a ton of wood chips, you would need to burn 54.9 gallons of #2 fuel oil.

The three fuels were burned in a small (3.5xl06 Btu/hr) firetube boiler designed for use in institutional, commercial, and light industrial applications. Emissions were measured for carbon monoxide (CO), carbon dioxide (CO2), oxides of nitrogen (NOX), and sulfur dioxide (SO2) using continuous emission monitors.
For comparison, the energy content of fuels is reported on a dry basis. For example, most agricultural residues have heating values that fall in the range of 14–19 MJ/kg (6,040–8,200 BTU/lb); coal ranges from 17–30 MJ/kg (7,300–1,3000 BTU/lb). Moisture
