Performance Assessment of a Boiler Combustion Process

The constructed vertical fire tube boiler is a low pressure boiler. The boiler is constructed so as to generate steam for chemical engineering processes, heating drying, sterilizing, etc. Holes at triangular pitch were drilled at the bottom and top sheet plates of the boiler. Steam tubes were passed through these holes and then welded strongly.

Modeling of fire-tube boilers - ScienceDirect

In fire-tube boilers, the flue gas passes inside boiler tubes, and heat is transferred to water on the shell side. A dynamic model has been developed for the analysis of boiler performance, and Matlab has been applied for integrating it. The mathematical model developed is based on the first principles of mass, energy and momentum conservations.
