Reduction of Carbon Dioxide Emissions from Coal-fired Generation of Electricity Regulations — 21
fuel type combusted in the unit during the calendar year, with “i” going from the number 1 to n, where n is the number of fossil fuels so combusted, F c,i is the fuel-specific carbon-based F-factor for each fossil fuel type “i” — being, as the case may be, the default value as set out in column 3 of the table to subsection (3) for that fuel type set out in column 2 or determined for that fuel type in accordance with Appendix A of the Reference Method — expressed in standard m 3 of CO 2 /GJ, HHV d,i — expressed in GJ/tonne, for a solid fuel, in GJ/kL, for a liquid fuel, and in GJ/standard m 3 , for a gaseous fuel — is, for each fossil fuel type “i”, (a) the default higher heating value set out in column 2 of Schedule 5 for that fuel type set out in column 1, and (b) in the absence of a default higher heating value for that fuel type referred to in paragraph (a), a default higher heating value for that fuel type established by a body that is internationally recognized as being competent to establish default higher heating values for fuels; (c) the volume of CO 2 emitted from the combustion of biomass in the unit during the calendar year, expressed in standard m 3 and referred to in this subsection as V bio , determined in accordance with the following formula: V T – V ff where V T is the sum of the volumes of CO 2 emitted from combustion of fuel in the unit during each hour of production of electricity during the calendar year, as determined under paragraph (a), and V ff is V ff determined in accordance with the formula set out in paragraph (b); and (d) the quantity of the CO 2 emissions from the combustion of biomass in the unit during the calendar year, namely E bio determined in accordance with the formula set out in subsection (1), based on the following two determinations: (i) the fraction of the volume of CO 2 emissions from all fuel combusted in the unit attributable to the combustion of biomass in the unit during the calendar year, referred to in this section as Bio fr , determined in accordance with the following formula: The formula for determining the fraction of the volume of CO2 emissions from all fuel combusted in the unit during the calendar year attributable to the combustion of biomass is the quotient of Vbio over VT. where V bio is the volume of CO 2 emitted from the combustion of biomass in the unit during the calendar year determined in accordance with the formula set out in paragraph (c), V T is the value of V T determined in accordance with the formula set out in paragraph (c), and (ii) the quantity of CO 2 emissions described by E bio determined in accordance with the following formula: (Bio fr × E u ) – E s where Bio fr is the fraction of the volume of CO 2 emissions from all fuel combusted in the unit attributable to the combustion of biomass in the unit during the calendar year determined in accordance with the formula set out in subparagraph (i), E u is the value of E u determined in the formula set out in subsection (1), and E s is the quantity of CO 2 emissions, expressed in tonnes, that is released from the use of sorbent to control the emission of sulphur dioxide from the unit during the calendar year, determined in accordance with the following formula: The formula for determining the value of CO2 emissions released from the use of sorbent during a calendar year is the product resulting from the multiplication of S, R and the quotient of the constant 44 over MMs. where S is the quantity of calcium carbonate (CaCO 3 ) or other sorbent material so used, expressed in tonnes, R is the stoichiometric ratio, on a mole fraction basis, of CO 2 released on usage of one mole of sorbent material, where R=1 if the sorbent material is CaCO 3 , and MM s is the molecular mass of the sorbent material, where MM s = 100 if the sorbent material is CaCO 3 . Default F-factor (3) The default value for the fuel-specific carbon-based F-factor for certain types of fossil fuel is set out in column 3 of the following table:
