When a project is originally designed, the designer must decide whether a natural draft or mechanical draft tower offers the best economic result. Mechanical draft towers are substantially less costly to purchase, but have the disadvantage of having a continuous auxiliary power draw. They are also physically smaller and shorter. Natural draft towers consume no auxiliary power, but are very expensive to purchase and erect. They are very large and tall. Often times, plants do not have enough "real estate" to fit such a large structure. One must do an economic analysis to establish which option is the best choice, economically. They are also simpler, not having any moving parts

Draft tube is used to increase the pressure from the low turbine exit pressure to the pressure of the surrounding to which the fluid is rejected.Only reaction turbines require a draft tube as there is low pressure at the exit of the turbine,where as in an impulse turbine the pressure at the inlet and the exit is essentially the same, which is above the pressure to which the fluid is rejected and thus it require no draft tube.

There "might" be a difference (splitting hairs) if one man flees to Canada (evading) verses another man burning his draft card (resisting). However, most people will probably agree that resisting/evading are both in the same category of draft resisting/draft evading/or draft dodging.
