![]() ![]() Where both the GT and boiler are being fired, or the GT alone, the GT ELV applies at 15% O2. Two different ELVs apply where a GT has a supplementary fired waste heat recovery boiler ( WHRB) – one for the GT and one for the boiler. You normally need to apply for a bespoke MCPD permit for this type of MCP. For example, where liquid fuel is used as a backup fuel if the natural gas supply is interrupted. Two different ELVs apply where different fuels are fired on the same MCP separately. For example, there will be negligible SO2 and particulate emissions from natural gas, therefore the ELV contribution from that fuel is zero. If one of the fuels is a gas or liquid there may not be an ELV for some pollutants. Then add together each fuel’s contribution to get the MCP’s aggregated ELV. divide the sum by the MCP’s total rated thermal inputĭo this calculation for each fuel.multiply the relevant Annex 2 ELV, corrected to the same common oxygen concentration where necessary, by the fuel’s thermal input (find the oxygen correction formula in Part 7 of the Industrial Emissions Directive).You then need to determine the fuel weighted ELV based on the: fuel consumption for the monitoring period. ![]()
