ENERGY AUDIT

Thermal Energy Audit
Thermal energy is generally obtained from firing of a fuel. The heat carrying mediums such as steam, Thermic fluid, hot air etc. forms the system that controls energy utilization. Thermal energy audit analyses the generation distribution and utilization system and highlights the gaps in energy performance. The report also provides firm actions to eliminate or minimize energy use for a given application or improve energy efficiency.

1. Fired equipment analysis
Boiler, Thermic fluid heater or hot air generator are fired equipment. The performance criteria of these equipment is measurable through its efficiency. There are standards, like BIS or DIN which provide guideline for performance evaluation of fired equipment and are used for efficiency evaluation. The report provides firm actions to improve efficiency. Possibility of fuel substitution for cost reduction is studied in detailed

2. Distribution System analysis
Heat losses through improper insulation and energy loss due to pressure drops in the pipeline are the two major causes of energy loss in distribution system. The TEA studies the entire system for its distribution effectiveness and suggests remedial action for improvement.

3. Analysis of Utilization of thermal energy
This is the most critical part of a TEA and requires process expertise ECPL provides a demand-supply analysis and energy level analysis to determine gaps in the performance specific design solutions like.
 Heat Wheels
 Heat Pipes
 Heat Pumps
 Thremocompressor etc. are studied against the present use. Process modification aiming at not only energy performance but also increase in throughputs is suggested for improvement in overall productivity.

4. Waste Heat Recovery
This is an integral part of the TEA and ECPL also offers exclusive services for Waste Heat Recovery. It is therefore listed under a separate heading.
The report contains energy conservation opportunities with their cost benefit impact.

Electrical Energy Audit
Electrical energy is the most extensively utilized form of energy due to its ease of utilization. The high energy level, electrical energy is used through mechanical devices like pumps, blowers, agitators etc. There are two distinct parts of electrical energy audit

Electrical System analysis
This part covers supply and distribution of electrical energy and losses associates with the electrical system inefficiencies. Common factors evaluated under this part are
 Tariff analysis
 Transformer loss analysis
 Power Factor improvement
 Lighting and auxiliary equipment
 Demand Management and reduction
 Cable size and rating analysis
 Motor efficiency analysis
 Power Quality study
(not included in normal energy audits)

Additionally the study may include
 Redundancy analysis and selection of appropriate backups mechanism (like DG sets sizing & selection)
 Disaster management planning for preventing electrical failures
 Electrical system adequacy and safety analysis

The report includes Gap analysis and (Design solutions) and exact remedial actions to be taken for system improvement.
