Cost-Effective Energy Conservation Techniques for Textile Spinning Mills

Abstract

The growing Indian economy calls for the urgent need to review the ways and means to conserve energy consumed by the industrial sector. As a part of fulfilling the objective, the Government of India has made it mandatory to conduct periodic energy audits in the bulk industrial sector to be followed up with a practical implementation of energy conservation (ECON) measures as suggested by the energy audit team. This paper presents the energy audit conducted in a medium-size textile mill in western Tamil Nadu of India. The energy audit has been conducted, and an exhaustive study of the energy consumption pattern of the mill has been carried out using tools like power quality analyzer, thermal leak detectors, air leakage detectors, and luminance meter. The qualitative data measured has been studied, and suitable site-specific and problem-specific methods, suggestions, and recommendations have been examined to yield substantial energy savings. The implementation of energy efficiency technologies and energy saving (ES) methods like effective use of the existing machinery, installing application-specific machinery, reduction/ avoiding energy wastage was also carried out. The conducted energy audit on the chosen textile leads to the reduction of energy consumption by almost 21 % per day. It saved company utility energy by nearly 13.59 %. This paper examines the recommendations and the subsequent energy efficiency implementations about specifically (i) energy demand management, (ii) equipment healthiness, and (iii) identification of energy wasted. The energy-saving outcome is elaborated with cost-effective planning and execution.
