Energy conservation filles the gap between supply and demand. Several measures for conservation of energy are very important for consideration. The energy audit can unearth huge profits to the industry. Saving of usable energy, which is otherwise wasted, has direct impact on economy, environment and long term availability of non-renewable energy resources. Energy conservation implies reduction in energy consumption by reducing losses and wastage by employing energy efficient means of generation and utilisation of energy. Opportunities to improve industrial energy efficiency are found throughout the industrial sector. Improved energy system efficiency can also contribute to a company's bottom line by increased production through better utilisation of equipment assets, greater reliability and reduced maintenance costs. This book summarises various aspects of energy consumption and conservation, and is divided into 21 chapters. It discusses: energy conservation in various industries such as food industry, chemical industry (petroleum refinery, fertiliser, pulp and paper), textile industry, cement, ceramic and glass industry, iron and steel industry and various equipment like boilers, motors, fans, compressors, etc. This book is a complete treatise on energy conservation and also includes a chapter on energy conservation in thermal power plants. It will be invaluable for professionals, industrialists and consultants in the respective fields.
