A top damper or cap damper is a metal spring door placed at the top of the chimney with a long metal chain that allows one to open and close the damper from the fire place.
The flow of flue gases in chimney due to difference in pressure i.e cold atmospheric air outside and hot gases in chmney is called as boiler draught.
Gland steam always send from bottom because if we send the gland steam from top then it has a tendency to pass directly to the bottom (condenser) .Due to this reason gland steam is send from bottom so that it occupies total turbine inside vacuum space and seal it.
it mean, things rising up from the bottom
It depends on what is meant by "bottom part" - does this refer to the entire machine, or the drill bit? See the related link below for a labelled diagram of a pillar drill.
The air pressure at the top of a chimney is lower than at the bottom because the height of the chimney creates a column of air inside that is lighter and less dense. As a result, the pressure at the top is lower due to the decrease in weight of the air column above it compared to the air at the bottom of the chimney.

It is best to start at the bottom and work up.

Smoke rises up the chimney partly because hot air rises and partly because it is pushed wind blowing across the top of a chimney lowers the air pressure there the higher pressure at the bottom pushes air and smoke up the chimney

so that the smoke is concentrated upwards
Hot air rises
It should be right below Mt chimney but not at the bottom more like in the middle.
Differences in air pressure create a pressure gradient that causes air to move from high pressure areas to low pressure areas. When the air inside the chimney is heated by the fire, it becomes less dense and rises. This creates a lower pressure inside the chimney relative to the outside air, which causes the smoke to be drawn up and out of the chimney.

A chimney chase is the structure through which chimney pipe is run.
