Flue Gas Desulfurizer mass and energy balance in 300 MW class subcritical Coal-Fired Power Plant for retrofit application

Based on the recent implementation of the Ministry of Life and Environment (MOLE) Regulation No. P.15/MENLHK/SETJEN/KUM.1/4/2019 regarding Power Plant Flue Gas Emission, which supersedes MOLE Regulation No. 21 year 2008, there is a reduction of maximum Sulfur Dioxide (SO2) concentration in flue gas emission of Coal-Fired Power Plant (CFPP), from 750 mg/Nm3 @7% O2 content (dry basis), to 550 mg/Nm3 in existing CFPP, and 200 mg/Nm3 in CFPP constructed after the implementation of the regulation. Thus, arises the necessity for the consumption of Coal with lower Sulfur (S) content and/or retrofitting of Flue Gas Desulfurizer System (FGD) system in CFPP, not yet equipped with the FGD system. One of the applicable systems for retrofit is Sea Water FGD (SWFGD). This paper explores the energy and mass balance aspect of the SWFGD system for application in 300 MW subcritical reheated steam CFPP. Operational aspect is the increase of allowable sulfur content in consumed coal up to 1,162%, when the plant is retrofitted with SWFGD, and an increase in condenser cooling water of 0.6 °C due to SWFGD Absorber interface.

Statistical process control for coal fired power plant system

<title/>In this study, the coal feeding process from Garp Lignite Enterprise (GLE) in Kutahya, Turkey to the nearby Tuncbilek Power Plant (TPP) was evaluated from statistical process control point of view. During the examination of GLE-TPP coal feeding system, process stability and capability of the supplied coal were measured and analysed on the basis of calorific value (quality characteristic) of coal for the years of 2002 and 2003. Process stability was examined by taking the mean and range control charts into account for the two units of TPP. Process capability, on the other hand, was analysed by considering the capability indexes for the two units of TPP. As a result of the analyses, it was found that the operation of the system was unstable and incapable in 2002 and 2003, although some improvements were observed in 2003. This result indicates that the process was not controlled effectively. After the analysis, the reasons of the problem were also discussed and several suggestions were made.
