Introduction to Emissions Monitoring
In the UK, large combustion, and waste incineration plants (EfW and biomass) must operate with a permit within the strict conditions of the Industrial Emissions Directive (IED 2010/75/EU).
The IED obligates plant operators to use Best Available Techniques (BAT) in emission monitoring. These techniques are outlined in Best Available Techniques reference documents (BREFs).
To monitor pollutants emitted to atmosphere and to ensure measurement parameters are within the permit, this is achieved using a Continuous Emissions Monitoring System (CEMS).
The Importance of MCERTS
MCERTS is the Environment Agency’s (EA) Monitoring Certification Scheme which covers monitoring activities.
Site operators using MCERTS approved monitoring equipment can take great confidence that it conforms to high performance International and European standards.
For sites that have permits issued by the EA, and fall under the Emissions Monitoring Directive (IED), Continuous Emissions Monitoring Systems (CEMS) should be installed.
Waste Incineration
In the UK, BREF (2019) requires WID plants to comply with the new emisison limits by 2023.
Waste incineration plants must meet emission limit values for selected pollutants:
- Sulphur Dioxide (SO2)
- Nitrogen Oxides (NOx)
- Hydrogen Chloride (HCl)
- Ammonia (NH3) – When plant uses SNCR to reduce NOx
- Carbon Monoxide (CO)
- Hydrogen Fluoride (HF)
- Hydrocarbons
- Particulates
- Mercury
- Dioxins
- Biogenic CO2
How to Select the Right CEMS
Legislation & Permit Knowhow
CEMS are a regulatory requirement to control emissions to atmosphere.
A sensible strategy for selecting the right CEMS to satisfy regulatory requirements is to start with your permit.
We help companies from the energy from waste and combustion sectors to:
- understand permit requirements now and what’s likely to happen in the near future – are there future proof opportunities?
- apply the relevant legislation to ensure the correct sampling techniques are applied
- implement the correct analytical methods based on the pollutants they need to monitor.
For example, if your permit requires ammonia to be monitored, we would recommend the MIR-FTIR because:
- It’s MCERTS approved
- Compliant with QAL1 & QAL3*
- Has the certified ELV ranges
- Accurate and stable technology in tough conditions
- Allows for upgrades to gas library
Project Management
Having the right CEMS is a complex process.
a1-cbiss has the experience of successfully delivering CEMS projects.
From initial contact, we like to meet your engineers, get a feel for your plant to understand the site conditions which will help to identify any issues that aren’t written into the permit.
The project is managed to keep you fully up to date with progress, communicate unexpected delays, ensures all equipment is installed to specification and meets timescale expectations.
Design
Following the site survey, our in-house design team discuss your project with the concept team to be able to design a system that meets the needs of your requirements using Best Available Techniques (BAT).
We consider everything from:
- gas analyser technology,
- certified ranges,
- product approvals,
- site conditions and available space,
- analyser housing and delivery
Installation & Commissioning
We undertake Factory Acceptance Tests (FATs) before equipment leaves our premises.
We take care of the delivery of the CEMS enclosure. Most enclosures are loaded by crane onto a flatbed truck and delivered to site before being manoeuvred into position.
Once onsite, we perform Site Acceptance Tests (SATs) to ensure total customer satisfaction and adherence to technical specification.

Raw Gas Measurement
Control Emissions Earlier in the Process
Control of stack emissions are no longer enough to ensure compliance with regulatory ELVs. Raw gas measurement provides the opportunity to optimise the process by recording the level of pollutants in the gas stream to enhance abatement control.
Lower the Cost of Reagents
Raw gas measurement analysers provide you with the level of pollutants there are in the gas stream prior to abatement. It can, therefore, help control how much reagents are needed without the risk of overdosing (and overpaying).
Dependable, Low Maintenance
TDL method is a non-contact optical, laser technology. The sensor stays protected from any contamination or corrosion and so the maintenance operation and the cost of operation are very low compared to other technologies.
Bulk Flow Measurement
There are many benefits to measuring and monitoring the flow of powders, granules, and dust in bulk handling processes.
Maintain Flow
Reliable limit level monitoring provides a consistent flow of fuel within the falling chute to guarantee a constant incineration process.
Control Cost of Reagent
Regulate accurate volumes of reagents in the scrubber to manage cost control.
Accurate Flow Speed
Measures the volume of solid materials to regulate speed control.
Identify Blockages to Maintain Efficiency
Flow detectors measure the continuous flow of materials and alert if a jam or blockage has occurred.
Prevent Overflowing
Continuous level measurement is necessary.
