Performance Analysis, Savings and Modifications in Compressed Air System of Manufacturing Industry.

Abstract

In the present scenario importance of an energy conservation increased day by day. There are various utilities in industries in practice like Chillers, Cooling Towers, Blowers, Fans, Motors, Furnaces, Pumps and Air Compressors in manufacturing industries plays vial role in energy consumption. Energy savings is possible increasing either the efficiency or replacement by efficient utility. It has been found that among all the utilities, Air Compressors are the least efficient utilities. It has been observed that compressed air system installed in early stage and due to ageing effect as well as lack of maintenance an efficiency of compressor is dropped down. In proposed work, Performance analysis of four air compressors has been carried out using “pump up test” (PUT) and losses by “leakage test” at different locations has been calculated large scale gear manufacturing industry. Considerable solution in terms of savings has been provided by providing priority base run of air compressors. Additional solution with variable frequency drive has also been also proposed. It has been proved that alternation of both mentioned test able to provide 5-15% additional amount of energy savings.

Patterns and prevalence of benign breast disease in Western India

“…11 Sagar et al reported, 78.13% cases with a painless lump while rest were painful. 12 Distribution pattern of benign breast disease with comparison with other studies is shown in 2,6,11,12 In the present study, 78 patients of fibroadenoma presented with lump in the left breast (48%) followed by right breast 73 (45%) and bilateral fibroadenoma of breasts was seen in 12 cases (7%). Sangma et al1 noted 48% lesions in right breast and 40% in left breast, while Bagale et al noted 95% cases in left breast and rest were detected in both breasts.…”

“…Most of the cases (6) were seen in 4th (2). Right breast were involved in 5 patients and left breast were involved in 4 patients.…”

“…1,4,14 Microscopically in fibrocystic disease, Prajapati et al noted cystic change, apocrine metaplasia, fibrosis, calcification, chronic inflammation and epithelial hyperplasia. 2 Bagale et al noted fibrocystic changes ranging from focus of abscess, areas of sclerosing adenosis to florid proliferative lesions. 4 Gynaecomastia constitutes 4.3% of all benign neoplasms in present study, while Bagale et al reported 2.25% incidence of gynaecomastia with left breast involvement in 54.55% cases, right breast in 18% cases and bilateral involvement in 27.27% cases.…”

“…1 Benign breast lesions deserve attention because of their high prevalence, their impact on women's life and due to cancerous potential of some histological types. 2 Treatment of BBDS is preservation of breast tissue as far as possible in contrast to traumatizing mutilating surgeries in breast cancers. Hence awareness and terminologies of benign breast diseases should be there amongst general population and clinicians.…”
