Emission Monitoring for Cement, Lime and Steel Plants
Overview
Cement, lime and steel plants face a distinctive combination of challenge: extreme flue gas temperatures, high dust loading, sticky or oxidising species that damage sampling lines, and process emissions that vary significantly with production state. The instruments have to survive the duct and produce a result that survives the regulator.
The compliance picture
Emissions are assessed against a named method, not against a concentration in isolation. The table below lists the parameters this sector is regulated on, the methods that apply, and what each method actually determines.
| Parameter | Method / standard | What it determines |
|---|---|---|
| Stack particulate matter | GB/T 16157-1996 · HJ/T 48-1999 |
Isokinetic gravimetric; kilns and sinter plants run continuously |
| Process gas composition | HJ 1131-2020 · HJ 1132-2020 |
SO₂ and NOₓ by constant-potential electrolysis |
| Flow and velocity determination | HJ/T 47-1999 |
Pitot and thermal methods; velocity under 45 m/s typical |
| Dioxins | GB 16445-2014 |
Co-incident with particulate sampling at cement kilns |
| Heavy metals | HJ 25.3-2019 class |
Particulate and gas phase sampling for metal content |
| Mercury | HJ 57-2017 |
At waste-heat kilns and sinter plants |
Recommended instrument set
The following combination covers routine compliance testing, screening ahead of a full test, and the reference data a defensible submission needs. Every model is configurable at order — state your range, gas and output protocol and the configuration will be confirmed in the quotation.

Common challenges in this sector
The problems below come up repeatedly in enquiries from this sector. They are engineering constraints, not sales objections, and the right answer is to specify around them rather than discover them on site.
Sinter plant flue gas is hot enough to destroy a standard sampling line
Heat tracing and an extended-temperature probe are not optional here. The 1089A provides configurable heat tracing from 100 to 160 °C with PTFE gas paths rated to 200 °C; specify the heated option explicitly when quoting.
A kiln test that takes 2–4 hours will not stay isokinetic through a production change
Test during a steady production state and record the production rate for the period. If the process cannot be held steady, the correct approach is repeated short tests with the data averaged, not one long test — and this decision belongs to your accredited tester, not to the instrument.
Sticky or oxidising particulate blocks filters and pumps faster than in other sectors
The visible dust-filter core on the 3012 series is designed for tool-free replacement in the field specifically so a blocked filter does not end a test. Plan filter changes into the test schedule rather than treating them as failures.
Documents to have ready
Having the applicable documents in hand before the enquiry shortens the quotation cycle and avoids specifying an instrument against the wrong method. These are the references most frequently requested in this sector.
