The Textile Engineering & Instrumentation Division offers the following services
1. Comprehensive Energy Audit
Conservation and management of energy have assumed tremendous significance in the last decade. SITRA has been conducting different types of energy audits like Comprehensive Energy Audit, BEE Mandatory Energy Audit and BEE Monitoring and Verification (M&V) Audit in the textile mills in India and abroad for more than four decades.
SITRA Energy Cell formed in 1980s, comprising of experienced engineers in the respective fields, is under taking Energy audits and energy consumption, conservation studies in the textile mills from powerhouse to production machines. So far, it has undertaken energy audits in about 650 mills in India and abroad. SITRA has also formulated procedures and systems for the introduction of Energy Conservation Program in mills for routine control and suggested methods to audit electrical energy consumption in mills. Many textile mills have saved crores of rupees in energy cost through SITRA Energy Audits. This audit is conducted in-depth in the following three areas:
2. BEE Mandatory Energy Audit
We are pleased to inform you that the Bureau of Energy Efficiency (BEE), Ministry of power, Government of India has approved SITRA to carry out BEE mandatory energy audit PAT Cycle. The details of the empanelment are available on BEE’s website www.bee-india.nic.in.
We are thankful to BEE for recognizing SITRA’s expertise in the area of energy audits and its Energy cell comprising of experienced engineers in various disciplines such as Electrical, Mechanical and Textile engineering which has been offering these services since the 1980s. We hope to carry on the good work of the past 4 decades in the area of energy management through services like energy audits (more than 650 in India and abroad), energy conservation studies and training programmes.
3. BEE Monitoring & Verification (M&V)
We are pleased to inform you that the Bureau of Energy Efficiency (BEE), Ministry of power, Government of India has approved SITRA as an empanelled energy auditing firm to carry out Monitoring & Verification (M&V) under PAT Cycle, SITRA is exclusively empanelled to carry out Monitoring & Verification (M&V) only for the Textile sector under PAT Cycle III. The details of the empanelment are available on BEE’s website www.bee-india.nic.in.
We are thankful to BEE for recognising SITRA’s expertise in the area of energy audits and its Energy cell comprising of experienced engineers in various disciplines such as Electrical, Mechanical and Textile engineering which has been offering these services since the 1980s. We hope to carry on the good work of the past 4 decades in the area of energy management through services like energy audits (more than 1000 in India and abroad), energy conservation studies and training programmes.
4. Other Studies
Power Quality Audit
Study of parameters namely THD, “K” factor, cosφ and TPF, Hz, V, I, UbV, UbA(total harmonic distortions, “K” factor, displacement and true power factor, frequency, voltage, and current, capturing wave shape distortions, unbalance voltage and current) at vital nodes – power and harmonic flow study –– evaluation of kVAh and kWh consumption – study of harmonic impacts on transformers, motors, capacitors and cables.
PQ analytics – Evaluation of electrical failures and faults – a typical layout showing the best locations of harmonic filters and capacitors to maximizing filtering efficiency – PQ study suggestssuitable measures for reducing faults and cost of electricity, the methods and type of filters successful in culminating harmonic penalty, improving quality of power and performance of electrical system.
Humidification is an important supportive activity for the production of yarns and fabrics. With reference to energy cost, it consumes nearly 15%-20% of the total power bill of the mill. SITRA has been conducting in-depth analysis on the humidification system of textile mills in the following aspects:
Detailed heat load analysis in different departments.
- Plant capacity requirement with respect to supply, exhaust and pumping system.
- Design of the humidification plants.
- Design of the supply air ducts and diffusers.
- Design of the exhaust air trenches and floor grills.
- Pattern of temperature and humidity inside the departments.
- Loading of the motors in the humidification plants.
- Air distribution pattern inside the departments.
- Recommended lay-out for the supply and exhaust system for uniform distribution of air.
Compressed Air Audit
SITRA conducts detailed study on different types of compressors existing in the textile mills with respect to the following aspects:
- Air leakage study in the existing condition.
- Existing compressed air pipe line lay-out.
- Modified pipe line lay-out for minimum air friction loss.
- Selection of energy efficient compressed air accessories like filters, dryers and moisture separators.
- Compressed air for cleaning.
- Power consumption pattern of compressors.
Compressor Air Flow Measurement
Compressor Free Air Delivery is measured using flow sensors to know the compressor output Air. This measurement is used to find out the Specific energy consumption of the compressor in kw/cfm. This study helps the mill to identify the inefficient compressors.
Noise level study
Noise is often a problem in the working environment, whether from production machinery in the factory or business machines in the office. Noise measurement permits precise scientific analysis of annoying sounds. Noise level measurements give a clear indication of when a sound may cause hearing damage and permit corrective measures to be taken. Hence, measurement and analysis of sound is a powerful diagnostic tool in noise reduction programme. SITRA conducts detailed sound level analysis at different sections of a textile mill with sophisticated state-of-the-art instruments.
Mill UKG Assessment Study
Assessment of existing Ukg level in the mill is vital for ascertaining energy saving potential in mills. SITRA has developed standard procedure for calculating a spinning mill’s 40s converted Ukg using conversion factors and 4.10 Ukg in the present standard for single yarn production. Best mills are able to achieve a 40s adjusted Ukg below 3.8. This study will help the mill to standardize their Ukg assessment procedure for comparison with industry and SITRA standards and monitor and analyse periodic variation in mill values.
SITRA 40s UKG conversion factors are approved and adopted by Bureau of Energy Efficiency (BEE) for their ‘PAT’ scheme which is designed / promoted to enhance energy efficiency in individual spinning mills in the textile sector
