    Fuels - Higher and Lower Calorific Values

    52 rows · Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:. A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter. If the initial and final temperatures of the water

    H. Liu, in Small and Micro Combined Heat and Power (CHP) Systems, 2011. 5.2.3 Calorific value. The calorific value of a fuel is the number of heat units evolved when unit mass (or unit volume in the case of a gas) of a fuel is completely burned and the combustion products are cooled to 298 K. This definition of calorific value includes the provision that the products of combustion are cooled

    Net calorific value. This is the calorific value of the fuel, excluding the energy in the steam discharged to the stack,and is the figure generally used to calculate boiler efficiencies. In broad terms: Accurate control of the amount of air is essential to boiler efficiency: Too much air will cool the furnace, and carry away useful heat.

    The energy provided by a fuel may be expressed in two ways - 'Gross' or 'Net' Calorific Value. Gross Calorific Value. This is the theoretical total of the energy in the fuel. The gross calorific value of the fuel includes the energy used for evaporating the water in the combustion process. The flue gases from boilers are in general not condensed.

    Fuel Consumption Calculation of Oil Fired Boiler-Zozen Boiler

    Taking a 10 ton oil fired boiler as an example, its thermal power is 7MW. Assuming that the combustion heat value of an oil-fired fuel is 42Mj/kg and the boiler fuel efficiency is 95%, it can be concluded that a 10-ton boiler needs fuel consumption per hour = 3600*7/42/0.95, which is about 630 kg.

    The oil boiler also supplies our domestic hot water. However, another factor that needs to be considered when determining which furnace (fuel oil vs propane) is the best value is Propane furnaces have a life expectancy of 15 to 20 years and a Fuel Oil furnace has a life expecctancy of 25 to 30 years. Another overall cost to consider.
