The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
to prevent loss of heat
The average lifespan of a boiler tube is 20 to 40 years. Boiler tubes are made out of heat-resistant carbon and low-alloy steel.
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
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.

Purpose of the boiler drum is to collect steam from all the various tubes in a boiler, and send it to the turbine to spin the generator
In a fire tube boiler, the water surrounds a set of tubes through which the fire and the products of combustion travel (as opposed to a water tube boiler, in which the water travels through the tubes, and the fire surrounds the tubes).The HVAC Veteran
The stay tubes basically hold the boiler together, they are thicker than the ordinary tubes and generally dont need to be replaced as often.
The answer is in the name. Boilers are made with a "tube - in - shell" construction, and the name implies what is in the tube. In a water tube boiler, the water circulates through the tubes, and the burner is usually under them. Most of the time, the "shell" of this style of boiler would not be watertight. A fire tube boiler has a watertight outer jacket with tubes through the center of it. The flame is shot through the tubes.

Pent house is a desirable living room for headers, raiser tubes & hangers at the top of the boiler
In water a lot of impurities are present when we use such water it will produce slice formation inside the tube of boiler due to which there is slice formation takes place and heat will not transfer properly . temperature of the boiler tubes are about 1400 degree centigrade.if heat is not flow properly through tubes then tubes will melt.

Effect of low water level in the boiler is rapid increase the temperature of the metal tubes, causing a collapse or rupture.
The average lifespan of a boiler tube is 20 to 40 years. Boiler tubes are made out of heat-resistant carbon and low-alloy steel.
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
