Unburned fuel ( usually and ) discharged from the system represents a heating value loss ( as well as a safety hazard ).
32.
When the lower heating value ( LHV ) is determined, cooling is stopped at 150 �C and the reaction heat is only partially recovered.
33.
The solid portion consists mainly of lignin which possesses a high heating value, thus making it an ideal fuel for burning in a boiler.
34.
Biomass cofiring with coal, by contrast, typically occurs at efficiencies near those of the coal combustor ( 30 40 %, higher heating value basis ).
35.
The lower heating value ( LHV ) is used for internal combustion engine efficiency calculations because the heat at temperatures below cannot be put to use.
36.
A high COP of a heat pump may not entirely overcome a relatively high cost for electricity compared with the same heating value from natural gas.
37.
Examples : diesel the higher heating value exceeds the lower heating value by about 10 % and 7 % respectively, and for natural gas about 11 %.
38.
Examples : diesel the higher heating value exceeds the lower heating value by about 10 % and 7 % respectively, and for natural gas about 11 %.
39.
Philippine coal is generally of low rank quality, with an average heating value of 8, 810 British thermal units per pound, 1 % sulfur, and 15 % ash.
40.
Generally, if you change fuel gases, the orifice is changed to provide roughly the same heating value with the new gas as you had with the old gas.
