Solid fuel fired boiler combustion control using Fuzzy Logic Algorithm

There will be waste of fuel causing economical loss and effects on environment due to improper combustion of fuel and air in boiler. Thus boiler combustion control need to be perfect and able to provide a continuous supply of steam at desired load demand. A single loop PID controllers are mostly used for combustion control of solid fuel fired boiler because of their simple structure and are easy to design. However PIDs are unable to control combustion control of solid fuel boiler with continuously varying demand. This results in improper combustion of fuel and air which in turn affecting performance of boiler. Therefore efficiency of boiler get reduced. This paper presents fuzzy logic based combustion control. We simulate this control scheme in Matlab and then on controller. At the end, output gives better boiler combustion control.
