Steam boiler is an integral and important component of steam turbine used for electricity generation. Its design is however complex, time consuming and prone to errors if done manually. In this study, we report the application of computer based approach to design palm kernel shell combusting furnace for generating a desired amount of electricity. Using backward calculation approach, standard design equations were used to size furnace and its components. The equations were coded and solved using C-Sharp programming language. The results showed that to generate 5 kW of electricity from palm kernel shell; 5.5 kW turbines, 3.6 m super heater, 3.2 m riser, furnace of 1.432 m height and 0.45 m3 volume were required having considered power loss due to friction and others. While these results are in good agreement with those calculated manually, human errors are virtually eliminated. In addition, calculations and drafting time were reduced from 5 hrs 47 mins when done manually to about 4 mins when the developed code was used. This code can be used to size boiler for any desired power output.
