Thermal Performance and Economic Analysis of 210 …

This paper presents the thermal and economic performance of a 210 MWe coal-fired power plant situated in North India. Analysis is used to predict coal consumption rate, overall thermal efficiency, mass flow rate of steam through boiler, and Net present value (NPV) of plant for given load. Thermodynamic analysis was carried out using mass and energy equations followed by empirical correlations.

Operation of Boiler and Conductivity in Drum Water …

Water chemistry sensors for both feed water and boiler need monitoring as any impurities in this gets concentrated and gets carried over in the steam. Conductivity controls for water blowdown in the drum type boiler are a method to remove such concentrate. Conductivity is just one of many factors to monitor. Changes in conductivity readings in various area gives a good clue to operators to
