Thermal Oil Heater Efficiency Calculation

Taking a 10 ton oil fired boiler as an example its thermal power is 7mw.

Thermal oil heater efficiency calculation. It may be worth considering a more efficient furnace as less energy will be used to achieve the same heat output. Cop the change in the heat level of an area the energy consumed. System efficiency measure of the percentage of potential energy contained in a fuel source that actually gets delivered as heat within a home heating system i e an 85 efficient system wastes 15 of its heating potential. Smart thermostats can also improve the efficiency of your heating and cooling system.

Cop is expressed as. Boiler efficiency is in general indicated by either thermal efficiency or fuel to fluid efficiency depending the context. Boiler efficiency calculation formula boiler efficiency q h h q gcv 100 heat exported by the fluid enthalpy of steam kcal kg enthalpy of water kcal kg gross calorific value of the fuel x 100 steam boiler efficiency boiler performance. Air is assumed to be dry at atmospheric pressure and at zero elevation.

Acfm is assumed to be at the average air temperature. However if a furnace is rated at 100 000 btus and is 92 efficient then the heat output will be 92 000 btus 100 000 x 92. Fluid properties are used at the average temperatures. Boiler efficiency 100 heat exported by the fluid water steam heat provided by the fuel 1.

Calculation assumes true counter flow. Cop thermal output btu hr power input kw 3413 btu kwh or. In thermodynamics the thermal efficiency is a dimensionless performance measure of a device that uses thermal energy such as an internal combustion engine a steam turbine or a steam engine a boiler furnace or a refrigerator for example. The comparison thus far has focused purely on the amount of heat equivalent amounts each fuel produces.

Use a smart thermostat. Nitrogen 1 61 carbon dioxide 0 15 methane 98 17 ethane 0 008 fuel gas lhv 20 814 btu lb fuel gas hhv 23 115 btu lb fuel gas temperature 100 f fuel gas pressure 50 psig excess oxygen. 140 000 x 90 percent 126 000 btu gallon for heating oil. For a heat engine thermal efficiency is the fraction of the energy added by heat primary energy that is converted to net work output secondary energy.

50 fuel gas composition vol. 3600 thermal power fuel calorific value boiler thermal efficiency. This is the measure of the energy efficiency of a system s ability to change the thermal conditions of an area based on the ratio of energy input relative to energy output. Fluid temperature ranges from 40 f to 200 f.

Liquids are considered incompressible. Only sensible heat transfer occurs. Even adjusting for efficiency heating oil still produces more heat per gallon than propane.
