Waste-fired power plant

The problem becomes transparent using the example of wastewater from a flue gas scrubber system in a waste-fired power plant (Figure 16.6). A seemingly... 

Reductions in U.S. mercuiy emissions from medical and municipal waste incinerators and other industrial sectors have already occurred. Additional emission reductions from some coal-fired power plants have also already begun as co-benefits from technologies used to control SO2 and NO emissions. These mercury emissions from power plants are, however, expected to be reduced further over the next few decades. Meanwhile, changes in mercuiy emissions in other parts of the world may also affect some U.S. ecosystems. 

Bayer MaterialScience (Germany) in the Project "Dream Production" combines part of waste streams of coal-fired power plants, CO2, with the production of polymers. The target is the design and development of a technical process able to produce C02-based polyether polycarbonate polyols on a large scale. The first step was to convert the C02 in new polyols, and these polyols showed similar properties such as products already on the market and can be processed in conventional plans as well (Figure 22). 

Exposure of humans and wildlife to arsenic may occur through air (emissions from smelters, coal-fired power plants, herbicide sprays), water (mine tailings runoff, smelter wastes, natural mineralization), and food (especially seafoods). 

Thermal reactions leading to the PCDD/F emissions are connected with technological and domestic combustion. PCDD/Fs were found in the emissions of the various combustion processes independently from the fuel municipal and hazardous waste incinerators, power plants with fossil fuels, automobile exhaust, private heating and fire places, wood and forest fires,...

Co-burning is a commercially available, ex situ technology for the treatment of nonhazardous tar and tar-contaminated soils from former manufactured gas plant (MGP) sites. The process burns MGP waste with coal in existing utility boilers at coal-fired power plants. 

Ash waste from combustion of oil shale is used in the cement industry, but other applications analogous to those found for ash from coal-fired power plants should be investigated (Hanni 1996 Manz 1999 Hall Livingstone 2002 Swanepoel Strydom 2002 Woolard et al. 2002). 

CDDs are released into the air in emissions from municipal solid waste and industrial incinerators. Exhaust from vehicles powered with leaded and unleaded gasoline and diesel fuel also release CDDs to the air. Other sources of CDDs in air include emissions from oil- or coal-fired power plants, burning of chlorinated compounds such as PCBs, and cigarette smoke. CDDs formed during combustion processes are associated with small particles in the air, such as ash. The larger particles will be deposited close to the emission source, while very small particles may be...

The conversion of biomass and waste into electricity and heat is increasingly performed by the coal-fired power plants in the Netherlands. The main objective is the reduction of CO2 emissions from the combustion of fossil fuels, and subsequently the reduction of the contribution of coal-fired power plants to the potential hazard of global warming. 

This priority order ensures that co-combustion of waste is only possible in case the waste cannot be re-used or when formation cannot be avoided. Each plan for cocombustion of waste in coal-fired power plants is therefore tested on its order in priority. An Environmental Impact Study is often mandated or desired by the national administration and/or regional authorities, who discuss and compare the possibilities for reutilization and alternative processing routes (for exanqile by means of a Life Cycle Analysis) (KEMA, 1999). 

Experience with energy recovery from specific monostreams of biomass/waste, in the Netherlands concentrates on direct co-combustion in coal-fired power stations (Beekes et al., 1998). In the year 2000 the Dutch coal-fired power plants will be responsible for utilising electricity from 900 kton/annum biomass/waste. At present different routes for direct co-combustion in coal-fired power stations are in operation or in preparation (figure 1). 

The contribution of biomass and waste to electricity production in the Dutch coal-fired power plants is very rapidly increasing due to both political and economical incentives and is stimulated by fiscal measures. 

In the year 2000 the coal-fired power plants in the Netherlands are producing sustainable electricity by means of direct co-combustion of more than 900 kton of biomass and waste. Stand-alone installations (for example Cuyk, Amer) contribute...
