India is striving to conserve coal and slash its carbon emissions. The country which depended on coal for 56% of its total capacity of 356 GW as of May 2019, wants to reduce coal’s share to 45% of a planned capacity expansion to 480 GW by the end of 2022. During that period, it will […]

Water quality monitoring and control are two of the most critical operations that power plants employ to protect assets, such as boilers and steam turbines, from corrosion by assuring the correct addition of

It is fairly common for power plant engineers and maintenance managers to focus on fireside issues rather than waterside issues during routine maintenance outages. However, that could be a mistake. Waterside

Thermohydraulic simulations can provide detailed heat recovery steam generator (HRSG) data to help determine the root cause of failures, predict the degree of wear from various mechanisms, and assess the

What is the best way to construct a complete chemical-feed system for use in a power plant—piecing together equipment acquired from a hodgepodge of suppliers or creating a system with components sourced from

Tests of a boiler combustion tuning system employing artificial intelligence (AI) at a Taiwanese coal-fired power unit verify improvements to fuel economy that could ultimately reduce costs by up to $1 million annually, Mitsubishi Hitachi Power Systems (MHPS) announced on June 11.
