Combustion volume

Based on the total combustion volume which includes space between the bed and the convective tubes. 

The flue gas is diluted with air at a ratio that is known as F, i.e. VIVo, where V = actual flue gas volume and Vo = the stoichiometric combustion volume. 

The heat of combustion of solids or liquids is usually measured in a device known as an oxygen bomb calorimeter. Such a device operates at a constant volume between states 1 and 2, and its heat loss is measured by means of the temperature rise to a surrounding water-bath. This is schematically shown in Figure 2.2. The combustion volume is charged with oxygen and a special fuel is added to ensure complete combustion of the fuel to be measured. Since the process is at constant volume (V), we have...

In a confined volume (eg, in a ballistic closed vessel or bomb) the pressure increases to the maximum value pmax in a weapon, it decreases beyond the maximum point because the combustion volume increases due to the movement of the projectile...

This design permits far greater utilization of the combustion volume and overall reformer envelope than is possible using conventional radiant box systems, leading directly to real economies in investment and operating cost.

Although the onset of end gas autoignition is influenced primarily by the autoignition chemistry in the end gas, it is also affected by the speed with which the flame propagates across the combustion volume. This is because the pressure and temperature of the end gas depend, not only...

For the gas-fired burners, a pre-purge of fhe test combustion volume in the case of oil-fired and dual-fuel burners testing plays a very important role in the operating procedure. The purging time has to be sufficient to provide four air volume changes in fhe combusfion...

In fuel-fired furnaces, heat release rate is usually expressed in heat units liberated per unit of furnace volume in unit time, commonly in Btu/ft hr or MJ/m hr. Closely related to rate of furnace heat release is the combustion volume or flame volume. Generally, the furnace volume should be at least equal to the sum of the maximum flame volume and the maximum load volume. The volume of the flame is a function of the combustion intensity condition discussed with table 3.1 subsequently, and where Fc is a configuration factor to assure that all of any one flame s volume is contiguous.

In Figure 4.3 [5] we can see some details of a diesel engine illustrating the heavy design and the lack of a spark plug. It is common for diesel engines to use compression ratio of 22 1 or more and some of the technical design is in the inverted hemispherical combustion chamber shape in the top of the piston. The compression ratio (CR) is the total volume swept out by the movement of the piston from the lowest position to the top position plus the volume of the small combustion volume (in the top of the piston here) divided by the volume of the combustion chamber,...
