The performance of combustion equipment can be analysed by processing specific parameters such as combustion products (also known as exhaust, stack or flue gases), temperature (flue gas, air or fuel), mass flowrates (fuel or air) etc using the fundamental knowledge of combustion reaction as well as mass and energy calculations. It can be much easier and time saving by developing a simple combustion calculator or software.

This simple project requires you to develop a simple combustion analysis calculator using Microsoft Excel spreadsheet.

1. Before developing the software, a flow chart of the software development with appropriate assumptions should be constructed.

2. The programme should be designed such that the input parameters can be varied accordingly to produce the desired outputs.
