How to Improve Energy Effciciency in Boilers

Energy Efficiency is one of the major pillars towards achieving g Net-Zero by reducing Green House Gas (GHG) emission and thereby Global Warming. Hence it is of utmost importance that Boilers must be periodically tested for their performance assessment and compared with the design performance. Corrective actions to be taken by implementing cleaner technologies, Fuel […]

Practical Guide For Managing Major Overhauling of Power Plants

Preface The primary purpose of the periodic Major/ Medium overhauls in any power station is to ensure continuous generation of electricity reliably by reducing the ‘Mean Time between Failure (MTBF)” of all major equipment significantly. Major shutdowns in any power company/ production company contributes for a significant part to total planned outage. This procedure is […]
