By reducing the temperature setting of water heater from 60 degrees to 50 degrees C, one could save over 18 percent of the energy used at the higher setting. The possibility of utilizing waste heat from power plants, especially the super thermal stations, by setting up appropriate industries in the vicinity should be seriously considered. Coherent and efficient retrofit scenarios are commonly built on the basis of the knowledge of the degradation state of the building and its obsolescence. Energy saving is a social responsibility of every individual. Dirty tube lights and bulbs reflect less light and can absorb 50 percent of the light; dust your tube lights and lamps regularly. Step 9 - Prepare a Report Summarizing Audit Findings The results of our findings and recommendations are summarized in a final report. Instrumentation and monitoring systems for monitoring energy flows,.
Balance the three-phase power supply. This interactive approach brings together expert intuition and rational systematic verification. Ring frame is the final product of the spinning mill. Identifying the equipment, operational aspects and characteristic of power supply causing inefficient functioning, wastage of energy, increase in hydraulic or power losses etc. In fact, investors often demand guaranteed savings. Use low-slip or flat belts.
Use energy-efficient motors where economical. The increasing energy demand has an adverse effect on the environment and also an increasing pressure for a government. With exponential rise in demands, energy deficit is also rising with each passing day. This paper set forth some energy saving methods in a methodological approach, experienced during an energy audit in an institution. Blower fan working at full speed irrespective of fumes generated or not at rolling mill.
Drive operation studied and software designed accordingly, optimise the power consumption during idling of mill. It involves minimal interviews with site operating personnel, a brief review of facility utility bills and other operating data, and a walk-through of the facility to become familiar with the building operation and identify glaring areas of energy waste or inefficiency. It shows where the power consumption is more in the given system. One of the important ways of to improve the energy conservation is energy audit. Please check the 'Copyright Information' section for details of this license and what re-use is permitted. Make sure that refrigerator's rubber door seals are clean and tight.
Smooth start resulting in increased life of motor and mechanical system. In such cases retrofitting of utilities provides a cost effective solution than going for altering the existing building structures. Hence the life of the equipment increased. By means of adopting these techniques, significant energy saving can be realised. A major obstacle that had to overcome was the need to make suitable assumptions for missing detailed primary data. These combined improvements led to annual reductions of 4. Step 3 - Document Review During the initial visit and subsequent kick-off meeting, available facility documentation are reviewed with facility representatives.
Hence, start stop ratio of blowroom line has been tuned as 95:5 ratio. In small-scale industries, a mechanism of energy auditing, reporting and improvement in energy use should be instituted. Such an audit programme will help to keep focus on variations which occur in the energy costs, availability and reliability of supply of energy, decide on appropriate energy mix, identify energy conservation technologies, retrofit for energy conservation equipment etc. One of the best energy-saving devices is the light switch. Also, motor connection changed from delta to star.

This paper presents new data from 39 representative bank branches and results from a more in-depth analysis of information from energy audits in 11 typical bank branches throughout Greece. Recent studies in the field shows that, commercial building in India have an energy saving potential of 25% to 35%. The proposed retrofit measures consisted mainly of actions carried out on the air conditioning system, lighting or building envelope. Presence of a supervisor or monitoring of the level got avoided. The retrofit measures would have a payback period of 1.
For the developing country like India, the energy generated decides the economic growth of the country. High efficiency motors offer of 4 - 5% higher efficiency than standard motors 2. A comparison of energy use in some of the energy-intensive industries in India and their counterparts in developed countries is shown in Table 5. The following machines are arranged in an order lines 1, 2, 3 and material from one machine is conveyed to the next machine by means of air suction created by fans for removing the waste. Description Installed, kW Total load, % Blowroom 58. In fact, shutting computers down when you are finished using them actually reduces system wear - and saves energy.
By doing so, there is a considerable power saving in the machine. Use variable speed drives for large variable fan loads. For surface temperature, a leaf type probe is used with the same instrument. From the data, for producing 1 kg of yarn, on an average 8. Make sure that refrigerator is kept away from all sources of heat, including direct sunlight, radiators and appliances such as the oven, and cooking range.
