A combination boiler does two tasks, the first is to provide radiant heating to a building and the second is to provide hot water. The boiler can provide hot water to only one system at a time, but eliminates the need to have two boilers.
there are two types of boilers water tube and fire tube. fire tube boilers are divided in to two categories vertical and horizontal. this according to the construction of fire tubes. it is said that vertical boilers are inefficient than horizontal boilers. The vertical boiler is small capacity, and horizontal boiler is higher capacity, well, the horizontal boiler have many types according the drums, there are single drums boiler, and double drums boiler, while, the single drums boiler have fire tube boiler and water and fire tube boiler, double drums boiler is usually water tube boiler.
there are two water level indicators usually mounted in front of boiler to ascertain the level of water inside the boiler am explain construction and working on next page

It is the small space between two plates having water and at the other side of the plate hot gases are available to transfer heat to the boiler water. In fire tube boiler space between end plate and combustion chamber's end plate is called water leg.
A double boiler is usually used to melt choclate. You can make one yourself by using two pots and boiling water.
The zone of saturation and the water table share two zones of ground water.
The boiler itself consists of two principal parts: the furnace, which provides heat, usually by burning fuel, and the boiler proper, in which water is converted to steam by the heat piped in from the furnace.

A waterwall in a boiler is any furnace wall that is comprised of refractory and tubes in a water-tube boiler. The tubes are evenly spaced and generally connect to headers which in turn are connected back to the main generating bank of the boiler. They serve a two fold purpose here in that they capture heat that would otherwise escape to the atmosphere and help heat the water in the boiler. And they also help keep the refractory cool (relatively speaking) This prevents spalling of the refractory.
The two zones of groundwater are the saturated zone and unsaturated zone.The saturated zone is filled with water and is below the unsaturated zone. The unsaturated zone has water and air in its pores (tiny open spaces in the soil).
One is the fountain, which can only be placed on water, and the puddle are two water items in the Safari Zone
