Energy management in the Portuguese ceramic industry: analysis of real-world factories

Abstract

The Portuguese ceramic industry is characterized by SME industries with high thermal energy consumption. Thus, the implementation of energy efficiency measures should include no-cost solutions, which are generally not explored in literature. This paper analyses the energy profile of different ceramic sub-sectors to identify potential improvements to meet low-cost competition in the market. Preliminary results of the statistical analysis suggest inefficient energy management, with a particular focus on natural gas consumption. The studied factories could easily improve profits and reduce energy consumption through good kiln operating practices. Optimization of kiln ceramic load (2–18 %) and efficient combustion in the gas burners (1–11 %) are examples of no-cost strategies that promote significant energy savings and carbon emissions reduction
