Plant Boiler

The production activity of mankind using high-ash fossil fuels for electricity generation is steadily increasing ash waste and carbon dioxide emissions into the environment. The article proposes a variant of wasteless combustion of Ekibastuz coal in a melting reactor installed under the boiler; it is envisaged to obtain, in addition to steam of energy parameters, a melt suitable for the production of building materials, sublimates of zinc, gallium and germanium, to reduce emissions of "CO2" into the atmosphere and return to the process a part of carbon in "CO2". An energy-saving thermal diagram of a power plant boiler has been developed on the basis of the proposed technology for the reduction of "СО2, Н2О" of reactor waste gases with zinc vapor to "СО, Н2". The resulting excessive hydrogen will be used to displace elemental carbon from "CO". The spent reagent, zinc oxide, after recovering into zinc will be used again in the process. In case of implementation, CO2 emissions into the atmosphere will be cut up to 50%, the expected payback period of the proposed system will be 1.0 - 1.5 years.

Reduce Emissions

Abstract. This synthesis discusses the emissions of carbon dioxide from fossil-fuel combustion and cement production. While much is known about these emissions, there is still much that is unknown about the details surrounding these emissions. This synthesis explores our knowledge of these emissions in terms of why there is concern about them; how they are calculated; the major global efforts on inventorying them; their global, regional, and national totals at different spatial and temporal scales; how they are distributed on global grids (i.e. maps); how they are transported in models; and the uncertainties associated with these different aspects of the emissions. The magnitude of emissions from the combustion of fossil fuels has been almost continuously increasing with time since fossil fuels were first used by humans. Despite events in some nations specifically designed to reduce emissions, or which have had emissions reduction as a byproduct of other events, global total emissions continue their general increase with time. Global total fossil-fuel carbon dioxide emissions are known to within 10% uncertainty (95% confidence interval). Uncertainty on individual national total fossil-fuel carbon dioxide emissions range from a few percent to more than 50%. The information discussed in this manuscript synthesizes global, regional and national fossil-fuel carbon dioxide emissions, their distributions, their transport, and the associated uncertainties.

Uncertainty on individual national total fossil-fuel carbon dioxide emissions range from a few percent to more than 50 %. This manuscript concludes that carbon dioxide emissions from fossil-fuel combustion continue to increase with time and that while much is known about the overall characteristics of these emissions, much is still to be learned about the detailed characteristics of these emissions.

Reduce Carbon Dioxide

Carbon dioxide capture and geological storage is a technology that could be used to reduce carbon dioxide emissions to the atmosphere from large industrial installations such as fossil fuel-fired power stations by 80–90%. It involves the capture of carbon dioxide at a large industrial plant, its transport to a geological storage site and its long-term isolation in a geological storage reservoir. The technology has aroused considerable interest because it can help reduce emissions from fossil fuels which are likely to remain the dominant source of primary energy for decades to come. The main issues for the technology are cost and its implications for financing new or retrofitted plants, and the security of underground storage.
