To give an example, the emission factor for UK grid electricity in 2009 is 0.48322 kgCO. 2. per kWh generated (Defra 2011a), and so if a company uses 1,000 kWh of grid electricity the associated Scope 2 emissions are 483.22 kgCO. 2. . Country-specific emission factors for grid electricity are published for some countries, for example

Coal Mill Emission Factors. Emission rates were influenced markedly by the presence of abandoned oil and gas wells in the vicinity of the mine. Such wells appeared to increase the flow rate of methane into the mine by a factor of 2 to 30 in an active mine in the Pittsburgh coal seam.
The particulate emission factors vary with stove operating conditions as shown by previous work.1 The particulate emission factor is presented as a function of m/q (where m is the fuel load in kg and q is the fuel heat release rate in 104 watts) in Figure 2. This figure points out the increase in emission factor as the length of the burn increases.

1. Introduction. Emissions from domestic solid-fuel combustion in Ireland have been declining steadily since the introduction of the Air Pollution Act in 1987, with a rapid reduction in particulate matter and sulfur pollution in Dublin following the introduction of a ban on bituminous coal in 1990. 1,2 Subsequent amendments to the legislation to include limits on particulate matter emissions ...

Coal Mining and Production Industry Description and Practices Coal is one of the world's most plentiful energy resources, and its use is likely to quadruple by the year 2020. Coal occurs in a wide range of forms and qualities. There are two broad categories: (a) hard coal, which includes coking coal (used to produce steel) and other
2020 Grid Electricity Emissions Factors v1.3 – July 2020 2 Key terms • Dual reporting – Reporting both location-based and market-based emissions. • Generation – This is the emissions factor for the fuels burned to provide you with the energy that you have directly used. This will be part of your "Scope 2" emissions, although you have directly used the ...

Emission factors in this table are calculated from the feedstock consumption values in Table 3.13 based on the following feedstock carbon contents and heating values: Natural Gas: 56 kg CO2/GJ 48.0 GJ/tonne. Oil: 74 kg CO2/GJ 42.7 GJ/tonne. Coal: 93 kg CO2/GJ 27.3 GJ/tonne. Uncertainty values for this table are included in Table 3.27

1.1-2 EMISSION FACTORS 9/98 categorized as PC-fired systems even though the coal is crushed to a maximum size of about 4-mesh. The coal is fed tangentially, with primary air, into a horizonal cylindrical furnace. Smaller coal particles are burned in suspension while larger particles adhere to the molten layer of slag on the combustion chamber wall.
emission factors for coal combustion depend largely on the properties of the fuel and, to a lesser extent, on the combustion technology. Coal emission factors (Table A6.1–9) were developed for each province on the basis of the rank of the coal and the region of supply. Emission factors were based on data from chemical analysis of coal samples ...
Air Emission Factors for Metals Finishing Operations Glenn A. Zinkus, Zinkus Consulting Group and Kevin Klink, CH2M HILL It is widely known that limited air emission factor data related to electroplating and metals finishing operations are available. In recent years, EPA has published AP-42 emission factors related to certain
average sulfur content of coal and oil; emission test results or continuous emis-sion monitoring data if available; and se-lected process-related data required for application of emission factors. As with any survey activity, completed surveys were not received for every mill. In each survey, responses for about 300 mills were obtained.
