Heating Value - Clarke Energy

The energy input into a gas engine should be defined using the LHV of the fuel. Fuel suppliers will usually quote the HHV and it will be this measure that will be used when kWh unit charges are applied for the fuel. In the case of natural gas the ratio of HHV to LHV is approximately 1.108:1.

Oil (in medium efficiency central heating system) Heat Cost = $2.30 (price per gallon) ÷ [0.14 × 0.85 (efficiency)] = $19.33 per million Btu. Propane (in medium efficiency central heating system) Heat Cost = $3.14 (price per gallon) ÷ [0.0916 × 0.85 (efficiency)] = $40.33 per million Btu. Formula: Example

Assuming condition 1 is at standard conditions (15ºC, 288.15K), and condition 2 is at normal conditions (0ºC, 273.15K), the gas volume based flow rate can be converted as follows: 165.18 = V2 x (288.15 / 273.15) V2 = 156.58 nm3/hr (gives great nm3/h which is …

Appendix L. Combustion of Refinery Fuel Gas

Gas rate = 3600/122 x 0.088 x 10.76 = 27.94kW gross, or 27.94/1.11 = 25.17kW net. The manual gives 24.49kW net maximum – pretty close, but is the boiler slightly over-gassed (under is better than over)? If we stop at stage 2 above, we simply leave out the 10.76 figure: Gas flow rate = 3600/122 x 0.088 = 2.597m 3 /hour.

How to Calculate Gas Consumption in a Gas Boiler Burner?

Estimated Boiler Performance and Expected Plant Performance. Converting a boiler to natural gas typically decreases boiler efficiency because of the large quantity of hydrogen in natural gas. During combustion, the hydrogen is converted to water. Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency.
