Design of […]

Innovative approach of collecting and disposing coarse fly ash:

By H Ramakrishna Conventionally in most of the thermal power plants, ash from the Economiser (ECO) and Air Preheater (APH) hoppers will be evacuated in slurry form and mixed with the Bottom Ash (BA) which is also extracted in slurry form for further disposal. The ECO and APH ash will not be mixed with Fly […]

Steam Audit: A case study

By Bharat Yadav Energy cost is one of the significant contributors of production cost for most of the Industries. Hence, reduction in energy consumption electrical, thermal or in any other form always helps in business sustenance and growth. Moreover, as most of the energy is derived from fossil fuels, any reduction in energy consumption would also […]

Industrial process plants handling hydrocarbons and other fuels have experienced accidental explosions. Care is taken to minimize explosions in the plant design, however when such incidents occur; the consequences can be very severe involving loss of life, financial losses and effecting public safety. When a building in the plant is not located far enough from […]

Integration of renewable sources of electrical power with grid

By  S Jagadish, Priyanka P. Swain & S V S Prasad   The huge, ever growing demand for electrical energy has hitherto been primarily met through the combustion of fossil fuels, and conversion of heat liberated therefrom. The relentless exploitation of these non-renewable resources has raised questions regarding emission of greenhouse gases, particulate pollution, and […]
