Weba heat value of about 120,000 BTU per gallon, regular gasoline has a heat value of about 125,000 BTU per gallon, and diesel has a heat value of about 139,900 BTU per gallon. Health concerns Smoke from a wood fire often triggers good memo-ries of sitting around a campfire or keeping warm near a fireplace on a cold winter day. However, wood smoke WebMoisture reduces the heating value; air-dry wood has about 15 percent less heating value than oven-dry wood. Wood must be raised to a temperature of about 250 °C (about 480 °F) for a spark or flame to ignite it, but at a temperature of about 500 °C (about 930 °F) ignition is spontaneous.

Heating value is mostly a function of a fuel’s chemical composition and can be expressed in two ways: the higher heating value (HHV) or the lower heating value (LHV). HHV is the total amount of heat energy that is available in the fuel, including the energy contained in the water vapor in the exhaust gases. LHV is the same as HHV first christian church slidell laZwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2O(l), Br 2(l), I 2(s) and H 2SO 4(l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2O(g), Br 2(g), I 2(g) and SO 2(g). In both definitions the products for C, F, Cl and N are CO 2(g), HF(g), Cl 2(g) and N 2(g), respectively. evans fruit company mattawa wa
