Which gasifier has better tar converting capacity?(a) Counter current

1.	Which gasifier has better tar converting capacity?(a) Counter current gasifier(b) Cross draught gasifier(c) Co-current gasifier(d) Fluidized bed gasifierI have been asked this question in final exam.The above asked question is from Applications of Biogas & Gasifier topic in division Biomass Energy of Energy Engineering
Answer» The correct answer is (c) Co-current gasifier To elaborate: A SOLUTION to the problem of tar entrainment in the gas STREAM has been found by designing co-current or down DRAUGHT gasifiers, in which primary gasification air is introduced at or above the oxidation zone in the gasifier.
