Energy Conservation by the Application of Engineering Principles in a Large Industrial Plant

Abstract

This article presents the energy conservation of the wood furniture factory in Samutprakarn province by using engineering management technique. The electrical energy of 7,408,000 kWh per year or 25,988,055 Bath per year is mainly used in the processes including a heating energy system that is derived from wood scrap. After detailed audit, it was found that 8 measures have a potential to improve energy efficiency. 7 measures for electrical energy can reduce the energy of 479,837.60 kWh per year and the rest decreases heating energy of 120,297.15 MJ/Year or saving the scrap of 9.4 tons per year. In order to assess economic possibility, all measure also were considered. The result showed that it was worth to investment. In addition, specific energy consumption (SEC) can be improved from 0.57 kWh/ft3 to 0.54 kWh/ft3 or diminishing of 5.26 %
