Cost Optimization of a Ring Frame Unit

Abstract

India focuses on many sectors out of which much of its growth in energy consumption is expected to occur in the countries outside the Organisation for Co-operation Economic and Development (OCED) known as non-OCED where demand will be drawn by strong, long-term economic growth and India fits into this particular category. In this research, the spinning mill is considered for optimizing the parameters regarding the energy management with the real-time data taken from a ring frame unit of spinning mill, analysis is done to find the feasible operating conditions with the aim of minimizing the energy cost and increasing the profitability of the sector, thereby suggesting for the spinning mill sector in India.

Appendix 1

The additional energy cost (Rs.) at various speeds is calculated by subtracting the respective actual energy cost with the energy cost value of 16,000 rpm.

Example: Taking the energy cost of 18,000 rpm from Table 5, the additional energy cost is calculated as:

$${\text{Additional}}\;{\text{energy}}\;{\text{cost}} = 6720 - 4767 = {\text{Rs}}.\;2562$$

Similarly for the Additional energy consumed (units), Additional production (kg) and Additional profit (Rs.) are calculated for various speeds with the reference values of 16,000 rpm.

The profit per day is calculated as:

$${\text{Profit}}\;{\text{per}}\;{\text{day}} = (({\text{Profit}}/{\text{kg}}) \times {\text{Production}}\;{\text{per}}\;{\text{day}}) = {\text{Rs}} .\;5369.14$$
