heating value उदाहरण वाक्य

Since natural gas had twice the heating value of manufactured gas, the company took the bold step to convert its system to natural gas and build pipelines throughout the state.
A number comparable to the typical Monroney sticker's " pump-to-wheel " fuel efficiency can be calculated based on regulations from the Lower Heating Value ( LHV ) of gasoline ):
The vessel and its contents are then cooled to the original 25 �C and the higher heating value is determined as the heat released between identical initial and final temperatures.
While chemistry provides methods of calculating the heating value of a certain amount of a substance, there is a difference between this theoretical value and its application to real coal.
The calculation of cell voltage assuming no irreversibilities exist and all of the thermal energy is utilized by the reaction is referred to as the lower heating value ( LHV ).

The heating value of this coal is about 8, 400 BTU / lb ( 19.5 MJ / kg ) and at full load Jeffrey EC burns about of coal per hour.
For the purpose of comparison of different fuels the heating value may be expressed in terms of energy per volume which is known as the energy density expressed in MJ / liter.
Condensing boiler manufacturers claim that up to 98 % thermal efficiency can be achieved, compared to 70 %-80 % with conventional designs ( based on the higher heating value of fuels ).
It is also approximately equal to one thousand cubic feet ( Mcf ) of natural gas or exactly one Mcf of natural gas with a heating value of 1000 Btu / cf.
The adiabatic combustion temperature ( also known as the " adiabatic flame temperature " ) increases for higher heating values and inlet air and fuel temperatures and for stoichiometric air ratios approaching one.
