Boilers - How Steam Engines Work | HowStuffWorks

The boiler's job is to apply heat to water to create steam. There are two approaches: fire tube and water tube. A fire-tube boiler was more common in the 1800s. It consists of a tank of water perforated with pipes. The hot gases from a coal or wood fire run through the pipes to heat the water in the tank, as shown here:

What are the Different Components or Parts of a Boiler

In order to increase the insulation of boilers, we use the water wall tubes. In water wall tubes, water flows and takes away the heat surrounding it. Thus the heat inside the boiler does not get transmitted to the outside of the boiler. These are of three designs namely: water cooled with refractory covered studded tubes; Close pitched exposed
