MODEL AND CONTROL OF PARABOLIC TROUGH COLLECTOR FOR STEAM SUPPLY IN INDUSTRY: - CASE STUDY OF BEDELE BREWERY FACTORY

Abstract

Currently, most industries in Ethiopia use steam for a variety of purposes, including sanitary and pasteurization processes. This thesis shows how to use renewable energy instead of gas fuel for steam generation in a factory and how to use an advanced controller to manage the temperature level of the steam generator in a case study of the Bedele brewing factory. Currently, gas fuel is used in this factory’s boiler plant, and steam temperature is controlled using a PID controller. Because gas is a non-renewable energy source with high costs and environment affect, it is preferable to replace it with a renewable energy source such as solar energy. Furthermore, in the case of solar energy systems, advanced MPC controllers are preferred over PID controllers for predict the next value. This paper presents Model parabolic trough collector based on collected data to produce steam for pasteurization plant in Bedele brewery factory. Here, apply PTC technology using solar system. Additionally model MPC controller to supply fixed temperature of steam for pasteurization plant. Here, MPC control the temperature of steam with respect to given set point (413K). In this thesis, Analysis the performance of MPC interims of both steady state response and transient response. According to the thesis steady state error almost approximates to zero and preferable transient response result then PID controller. Therefore, MPC controller is more advisable for this temperature controlling system in this Factory.
