Sentence examples for minimum fluidization gas from inspiring English sources
This minimum fluidization gas velocity predicted from the numerical simulation is approximately equal to the superficial gas velocity of the bubbling fluidized bed combustor.
Minimum fluidization velocity and gas holdup are two of these key characteristics.
Experimental studies addressing the effects of bed height and material density on the minimum fluidization velocity and gas holdup were carried out in this study using a 10.2 cm diameter cylindrical fluidized bed.
The minimum fluidization velocity, bed voidage, gas holdup and gas-liquid volumetric mass transfer coefficient were measured in a 0.068 m i.d.
Beyond the minimum fluidization conditions the excess gas passes through the bed as bubbles.
The 'Flow Pattern Parameter (FPP)' consists of particle kinetic energy, bed aspect ratio (H/D), pore size of air distributor, minimum fluidization velocity, and superficial gas velocity.
To achieve and maintain a stable fluidization, knowledge about the pressure drop across the bed and minimum fluidization velocity of the gas flow introduced from the bottom of the bed are required.
Furthermore, gas flow balance calculations show that the ratio of dense phase superficial gas velocity to minimum fluidization velocity increases with both increasing pressure and excess gas velocity.
Based on the set of measurements obtained here we postulate that the jet height is independent of the bed dimensions at flow rates of Q<0.7Qmf and bed dimensions of L/dp>55, where Q is the volumetric flow rate of the gas, Qmf is the volumetric flow rate of the gas at minimum fluidization and dp is the particle diameter.
The bubble behavior is influenced by minimum fluidization velocity, as defined by gas and particle properties, and the injection rate.
As the superficial gas velocity is increased further above the minimum fluidization velocity of 1.0 m/s to the gas velocities 1.25 and 1.5 m/s as shown in Figs. 8 and 9, the pressure drop results across the bed area has been decreased.
