Energy Conservation Techniques For Industries - SlideShare

Energy Saving Tips. Energy prices have increased at an alarming rate, and interest in environmental responsibility is at an all time high. Many organizations are looking for ways to conserve energy, reduce carbon emissions, and save on overall utility costs.

Industrial Energy Saving Tips

Energy Conservation is the solar heat energy which is trapped by rocks deep within the earth. Scientists today have devised a way of utilising this energy for producing electricity and the other forms of energy. Can you now list the sources of energy? 14.2 SOURCES OF ENERGY Following are the various souces of energy: 1. Sun 2, Wind (wind mill) 3.

Cement Process & Energy Saving - ECCJ

Cement accounts for 83% of total energy use in the production of non-metallic minerals and 94% of CO 2 emissions. Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process.

The Cement Sustainability Initiative (CSI)

The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.


The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

The production of cement is an energy-intensive process. Annually the cement industry spends over $1 billion energy purchases. The production of cement results in the emission of carbon dioxide from both the consumption of fuels and from the calcination of limestone. This report briefly describes the various stages in the cement production process.

Bureau of Energy Efficiency First method is to restrict the air flow by partially closing a damper in the system. This action causes a new system performance curve (SC2) where the required pressure is greater for any given air flow. The fan will now operate at "B" to provide the reduced air flow Q2 against higher pressure P2.
