Boilers are an equipment that produces steam from various types of fuel. Of all the fossil fuels, coal is used widely as a core energy source, as it is exceptionally economical and offers an extremely stable supply.
The steam boilers may also be classified according to, to the source of heat supplied for producing steam. These sources may be the combustion of solid, liquid or gaseous fuel, electrical energy or nuclear energy, hot waste gases as by-products of other chemical processes etc. Types of Boilers. Some of the Different types of boilers are as follows:
Thermal stresses also occur as a result of thermal expansion, therefore a boiler must be designed to carry both thermal and pressure loads. In a Belpaire type firebox, the outer wrapper and crown sheet may be stiffened by beams or girder stayed to each other.
