Boiler is defined as a closed vessel in which water or other fluid is heated under pressure. The steam or hot fluid is then circulated out of the boiler for use in various process or heating applications.  In this site, we’d like to go beyond this definition and consider a boiler more than just a closed vessel, rather a process plant in which energy is generated for a noble use benefiting customers in their lively necessities.  Boilers are widely used in several industrial, communities, military, scientific, and medical applications requiring close and clear attention for the safety and benefits of users.

Several concepts in boiler subjects such as boiler fundamentals, engineering, operations, optimization, and components will be illustrated in simple terms to allow better understanding and hence better handling of boilers and all their related aspects.
