Abstract
The article considers issues related to the modernization of coal-fired power technologies. To increase the efficiency of energy resources, operational reliability, loss reduction and environmental safety the possibilities of trigeneration are considered with application of fuel cells, hydrogen technologies and RE-components that are expedient to use for additional electric energy production. The possibilities of innovative energy components to integrate them into traditional power generation systems are shown, technological schemes are given.
Highlights
The article considers issues related to the modernization of coal-fired power technologies
Proposed for consideration of potential transfer the mentioned technologies of cogeneration and trigeneration allow in preliminary estimates to achieve the following results: reduction of energy costs up to 70%; the efficiency of transformation and use of energy may reach up to 93% at place of production of electricity using natural gas; net payback period of the project may usually be from 2 to 5 years; additional savings of 10% to 20% due to heat recovery from existing flows of exhaust gases
The commercial benefits of cogeneration by the most advanced technologies can provide up to 70% savings in electricity costs, and an additional 10% to 20% savings in natural gas energy in heat utilization up to 90% of the losses from the existing exhaust heat flows
