Abstract
Integrated complexes for energy generation and industrial processing are an important component of an efficient energy system. These complexes allow the joint optimization of energy generation and product fabrication, while reducing environmental impact. This paper gives a comparative analysis of energy consumption by six variants of these energy-technology complexes: each combines specific fuel and chemical processing activity with a steam-turbine, steam-gas combined cycle, or magnetohydrodynamic power plant. Technologies for the preliminary in-cycle processing of fuel are based on the gasification or pyrolysis of coal. Electricity, synthetic liquid fuel, refined solid fuel, elemental sulfur, nitric acid, ammonia, and concentrates of ash elements are the main final products. It is shown here that in such complexes consumption of fuel for power generation may be reduced by 1.5–2.0 times relative to a standard steam-turbine power plant, owing to the coordination of technologies each solving a major task, optimization of the structure and parameters of each technology, and more complete utilization of fuel components, while ecological problems are simultaneously solved.
