Thermal power plants switching from traditional fuels to coal water slurries containing petrochemicals

Research output: Contribution to journalArticle

Abstract

The relevance of the research is caused by the effective utilization of numerous accumulated coal waste and oil refining in the compo sition of coal water slurry and coal water slurry containing petrochemicals, a significant reduction in consumption of minerals for ener gy, minimizing the impact of heat energy on public health and the state of nature. The main aim of the research is fuel supply systems transformation in switching thermal power plants from solid, liquid and gas fuel to coal water slurries containing petrochemicals; techno economic analysis of power generation facility switching to highpotential coal water slurries containing petrochemicals based on coal and oil processing waste. Object of the research is thermal power plant with electric and thermal capacity 300 MW and 800 Gcalhr respectively located in the Siberian region of the Russian Federation, type of primary fuel used – coal and nature gas, type of starting fuel and used – fuel oil. Methods: techno economic analysis of the efficiency of thermal power plant switching from traditional fuel to coal water slurry conta ining petrochemicals by calculating the fuel costs, operating costs, fuel storage costs, storing and disposal of bottom ash waste, pay ment of fines and environmental actions, fuel supply system costs. Results. Thermal power plant switching from traditional fuel to coal water slurry containing petrochemicals greatly simplifies the fuel supply systems as much less equipment is required to create such systems. During the production of total installed capacity of all coal fired power plants in the world due to the combustion of coal water slurry containing petrochemicals, the fuel costs saving can amount from hundreds of millions rubles up to tens of billions rubles in year.
