DEVELOPMENT OF GOOD COMBUSTION PRACTICE FOR MUNICIPAL WASTE COMBUSTORSt
نویسنده
چکیده
The U.S. Environmental Protection Agency is devel oping new air pollution rules for all new and existing municipal waste combustors (MWCs). These rules re quire all MWCs to use good combustion practice (GCP). The goals of GCP are to maximize furnace destruction of organic pollutants, limit the relative amount of particulate matter (PM) carried out of the combustor with flue gases (PM carryover), and ensure that the PM control device is operated at temperatures which do not result in formation of excessive amounts of chlorinated dibenzo-p-dioxins and chlorinated di benzofurans (CDD/CDF). This paper summarizes the rationale for EPA's GCP strategy. This strategy incor porates the use of three continuous compliance parame ters: carbon monoxide (CO) emissions, furnace steam load, and PM control device inlet temperature. Experi mental data are provided to show that furnace emission of organics is correlated with CO concentration, the amount of PM carryover (which is related to load), and temperature at the PM control device inlet. The relationships between the GCP compliance parameters and other combustion parameters which are necessary ingredients of good combustion (uniformity of waste feed, the amount and distribution of excess air, combus-

Gaseous emissions during concurrent combustion of biomass and non-recyclable municipal solid waste
BACKGROUND Biomass and municipal solid waste offer sustainable sources of energy; for example to meet heat and electricity demand in the form of combined cooling, heat and power. Combustion of biomass has a lesser impact than solid fossil fuels (e.g. coal) upon gas pollutant emissions, whilst energy recovery from municipal solid waste is a beneficial component of an integrated, sustainable wast...
متن کاملNumerical analysis of size reduction of municipal solid waste particles on the traveling grate of a waste-to-energy combustion chamber
The size reduction of municipal solid waste (MSW) particles on the reverse acting traveling grate of a waste-to-energy (WTE) combustion chamber was estimated by means of a numerical model combining the particle size distributions (PSD) of MSW and combustion residues and the Shrinking Core Model (SCM). This new integrated model was used to simulate the particle behavior on the grate. During thei...
متن کاملLife-Cycle Assessment of Waste Management Greenhouse Gas Emissions Using Municipal Waste Combustor Data
This paper compares life-cycle greenhouse gas GHG emissions from two municipal solid waste MSW management options, municipal waste combustion, and landfilling, using a U.S. EPA life-cycle assessment LCA model, the MSW Decision Support Tool. Unlike previously reported LCAs, key combustion model inputs—total MSW carbon content and its biogenic/fossil split—are determined not from MSW composition ...
متن کاملEffects of Burning Municipal Waste on Environment and Health
Source separation, recycling, combustion, and bene ficial use of ash residues are important components of plans for management of household and commercial wastes in order to minimize the cost and risks of landfilling. Municipal incinerators, originally built to avoid unsanitary landfills, are now becoming efficiently operated power plants. However, in order to obtain permits to build and opera...
