Regulations Limiting Carbon Dioxide Emissions from Natural Gas-fired Generation of Electricity — 14
Unit combusting biomass 14 (1) Subject to section 15 , the quantity of CO 2 emissions resulting from the combustion of fossil fuels in a unit combusting biomass in a calendar year that is measured using a CEMS must be determined in accordance with the following formula: E u × (V ff / V T ) – E s where E u is the quantity of CO 2 emissions, expressed in tonnes, from the unit, “u”, during the calendar year from the combustion of fuel, as measured by the CEMS, and calculated in accordance with sections 7.1 to 7.7 of the Reference Method; V ff is the volume of CO 2 emissions released from combustion of fossil fuel in the unit during the calendar year, expressed in standard m 3 and determined in accordance with the following formula: The formula is the sum of the products resulting from the multiplication of Qi, Fc,i and HHVi for each fossil fuel type “i”. where Q i is the quantity of fossil fuel type “i” combusted in the unit during the calendar year, determined (a) for a gaseous fuel, in the same manner used in the determination of V f in the formula set out in paragraph 18 (1)(a) and expressed in standard m 3 , (b) for a liquid fuel, in the same manner used in the determination of V f in the formula set out in paragraph 18 (1)(b) and expressed in kL, and (c) for a solid fuel, in the same manner used in the determination of M f in the formula set out in paragraph 18(1)(c) and expressed in tonnes, i is the i th fossil fuel type combusted in the unit during the calendar year, where “i” goes from the number 1 to n and 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 the factor set out in Appendix A of the Reference Method, or for fuels not listed, the one determined in accordance with that Appendix — corrected to be expressed in standard m 3 of CO 2 /GJ, and HHV i is the higher heating value for each fossil fuel type “i” that is measured in accordance with subsection (2), or in the absence of a measured higher heating value, the default higher heating value, set out in column 2 of Schedule 2, for the fuel type, as set out in column 1; V T is the volume of CO 2 emissions released from combustion of fuel — fossil fuel and biomass — in the unit during the calendar year determined in accordance with the following formula: The summation of the products of 0.01, CO2w,t and Qw,t for each hour “t”. where t is the t th hour, where “t” goes from the number 1 to n and where n is the total number of hours during which the unit generated electricity in the calendar year, CO 2w,t is the average concentration of CO 2 in relation to all gases in the stack emitted from the combustion of fuel in the unit during each hour “t”, during which the unit generated electricity in the calendar year — or, if applicable, a calculation made in accordance with section 7.4 of the Reference Method of that average concentration of CO 2 based on a measurement of the concentration of oxygen (O 2 ) in those gases in the stack — expressed as a percentage on a wet basis, and Q w,t is the average volumetric flow during that hour, measured on a wet basis by the stack gas volumetric flow monitor, expressed in standard m 3 ; 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: S × R × (44/MM s ) where S is the quantity of sorbent material, such as calcium carbonate (CaCO 3 ), 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, which is equal to 1 if the sorbent material is CaCO 3 , and MM s is the molecular mass of the sorbent material, which is equal to 100 if the sorbent material is CaCO 3 . Higher heating value (2) The higher heating value of a fuel is to be measured (a) for a gaseous fuel, (i) in accordance with wh
