The document discusses energy management and conservation in industrial processes. It notes that industrial sectors consume 50% of India's commercial energy and there is an estimated 25-30% potential for energy conservation. Common approaches to energy conservation include conducting energy audits, adopting new efficient technologies, improving capacity utilization, maintenance practices, and housekeeping. Preliminary energy audits focus on major energy supplies and demands, while detailed audits involve formal data collection, analysis, and testing over 1-10 weeks. Specific energy conservation measures for tea factories include reducing air leaks in furnaces and maintaining optimal furnace oil temperatures.

1. Energy Management

2. Energy Conservation
• Efficient Utilization of energy resources
ensuring the same level of industrial
activity with lesser inputs of energy
• 50 % of total commercial energy in
India is consumed by industrial sector
• Estimated energy conservation
potential of 25-30% exists in industrial
sector

3. Energy Conservation Approach
• Energy Audit
• New Efficient Technologies
• High Capacity Utilization
• Better Maintenance Practices
• Good House-Keeping Measures

4. Energy Audit
• Serves to identify all of the energy
streams into a facility
• Quantify energy use of the energy
streams into a facility
• Eg: Type of energy used as Natural
Gas, Coal, LDO-Low density oil

5. Types of Energy Audit
• Preliminary energy audit
• Detailed energy audit

6. Preliminary Energy Audit
• Focuses on major energy supplies and
demands
• Preliminary data gathering and analysis
effort
• Identification of obvious sources of
energy wastage
• Duration- 2 to 10 days

7. Detailed Energy Audit
• Questionnaire
• Data collection –Conduct formal
interview
• Data analysis –Database Development
• Tests conducted
• Examination of electrical systems
• Duration- 1 to 10 weeks

8. Energy Management
• North India
• CTC method uses only 3 sets of rollers
• South India
• CTC method uses 5 sets of rollers

9. Energy conservation in Tea
factory
• Furnace –Air leak in the furnace should
be avoided
• Furnace oil – Temp is maintained in the
range of 95 -105 deg C for good
atomization

10. Types of Energy
• Thermal Energy – 90 % -removal of
moisture
• North India- Coal & Natural gas
• South India -Firewood
• Electrical Energy -10% - Cutting –
Electrical/diesel generator
