I want to design the distributor plate and calculate the bubbles size and velocities for the reactor. The purpose of calculation is just to have an estimate before going any further with building the actual lab scale reactor.
I am using following correlations to calculate the bed height but the values clearly tells me that these correlations are not accurate.
H/Hmf = 1 + [10.978 (U - Umf)^0.738 dp^1.006 Rho_s^0.376 Umf^-0.937 Rho_g^-0.126]
Hfb = [D - (2.51 D^0.2)] / (0.13 D^0.47)
Hmax = 60 D^0.175
There are a lot of thumb rules to consider while designing the fluidized bed. I am not sure if bed height is one of those parameters that requires to be fixed by some thumb rule.
I would appreciate any help in finding the accurate correlation to calculate the bed heights for different velocities.
In the 70s - 80s, the British coal board carried out extensive r & d on fluidised bed combustion. This included a fluidised bed. I would expect theoretical models were tested against real life experiments and test beds. You may find the resulting body of research work within the current UK governmental department of industry and technology
Lawrence Gertig Thank you, let me search about it then. I hope to find something relevant. Thank you again...
Lawrence Gertig Thank you. I will surely come back to you for help if I am unable to resolve it :)
This is what ive found so far. If you search under national coal board : fluidised bed combustion I expect you'll be able to get some results
