Draft fan control using fuzzy logic in thermal power plant

Abstract

In a thermal power plant combustion process in the boilers plays a vital role and it has to be controlled effectively. At present, this is controlled using draft fans employed with DCS. This paper deals with the controlling process using Fuzzy logic. The goal of this task is to manage the Forced draft fan, Secondary air fan, Grid refining fan and induced draft fan in the boiler. Every one of these fans assumes a significant job in controlling the temperature of the boiler during the burning (combustion) procedure. Utilizing DCS to control the temperature is mind-boggling expense and furthermore it needs a different server, a processor and a workstation to complete the procedure. In the case of software based Fuzzy logic controller, the controlling process is the cheapest and the easiest method to maintain and control.
