GLOBAL ENERGY SCENARIO
Energy has become an important prerequisite for the economic development. Energy is a most problematic issue in the world. As a rule of thumb modern day manufacturing industries utilize at least 33% production cost in terms of energy prices. An increase of energy cost will affect their production cost and will force the manufacturers that either to reduce the labor cost or to remain competitive in market by improving the quality standards.
What to do in Energy Audit:
- Calculate energy losses in any industrial process.
- Calculate energy efficiency of equipment.
- Identification of energy saving and fast-payback energy retrofit opportunities.
- Provides essential information on how much, where and how energy is used within the factory.
- Comparison of performance against past future levels.
- Energy saving proposal with technical and economic analysis of projects.
- Development of energy saving projects with action plan in order of priority.
- Study of Power Factor Improvement and capacitor performance.
- Study of combustion & heating system in furnaces, Boilers, Kilns, etc.
- Study of waste heat recovery system.
Feasibility study: We identify, scope and justify the automation projects. Identify customer requirements and complete high-level analysis of the best way to meet the requirements.
System Design: Prepare the complete conceptual design of the control and information systems including specifications of the hardware and software.
- Boilers and Heater
- Compressed Air System
- Refrigeration System.
- Illumination System.
- Maintain efficient combustion.
- Maintain good water treatment.
- Repair water and steam leaks.
- Recover heat from flue gas and boiler blowdown whenever possible (see Steam guidebook).
- Ensure good operational control and consider sequence control for multi-plant installations).
- Attempt to match boilers to heat demand. Valve off idle boilers to reduce radiation losses.
- Use flue dampers where appropriate to minimize flue losses when the plant is not firing.
- Ensure that boilers and heat distribution systems are adequately insulated.
- Blowdown steam boilers only when necessary (see Steam guidebook).
- Ensure as much condensate as practicable is recovered from steam systems.
Insulate oil tanks and keep steam or electric heating to the minimum required
