Through calculating thematerial flow, itw as obtained that the open ra tio of sieve plates in the stripping tow erw ere aboutpositive proportional to the steam flow. Based on the calculation results, the capacity of the turbogrid stripping tower w ith ms all pore size sieve platesw as in creased through enlarging the pore diam eter of sieve plates.
