Abstract Information :
It is established that there are around 143 000 Medium combustion plants in the EU. They are used for a wide variety of applications such as electricity generation, domestic or residential heating and cooling, providing heat or steam for industrial processes and many more. Those plants are an important source of emissions of sulphur dioxide (SO2), nitrogen oxides (NOX) and dust.
Directive (EU) 2015/2193 on the limitation of emissions of certain pollutants into the air from MCPs known as the Medium Combustion Plant Directive (MCPD) regulates pollutant emissions from the combustion of fuels in plants with a rated thermal input equal to or greater than 1 Megawatt thermal (MWth) and less than 50 MWth. This MCPD regulates emissions of SO2, NOX and dust to air. To comply, it will require to monitor also carbon monoxide (CO) emissions. The emission limit values set in the MCPD apply from 20 December 2018 for new plants and 2025 or 2030 for existing plants, depending on their size.
The MCPD addresses the potential need for Member States to apply stricter emission limit values in areas where this can improve local air quality in a cost-effective way.
In order to meet with the requirements of the MCPD, ENVEA Group has launched a wide program of R&D to develop a new generation of NDIR (non-dispersive infrared) Continuous Emission Monitoring Analyser using the most advanced technology to achieve the goal of having a high precision, fast response time and cost effective instrument. Eco-designed, the monitor utilizes the most recent optical and electronic technologies offering increased precision and robustness, while requiring only limited maintenance. The instrument allows simultaneous multi-gas measurement of NOx, SO2, CO, O2, residual H2O, and optionally CO2, CH4 and N2O (greenhouse gases). The optimized design of a converter offers a very flexible and competitive tool to provide reliable NOx measure, as per most of the CEMS regulation using a standard NO analyser (be it multi gas or single gas). The APNOx allows for a compliant global NOx measurement without the need of a direct NO2 measurement.
This paper presents from one side, the summary of the Directive and the impact of this new MCPD in the next 5 years with regards to the concerned plants (actual and future) and, from the other side, the technical solution provided with a smart compliant analyser including AMS (automatic measuring system) control functionalities: integrated sampling control, automatic zero and span gas injection, external pump control, system alarms display... Original approach of the metrology is also technically described for a specific case study in a European plant.
