Continuous Emission Monitoring System (CEMS) for Chemical Boilers
The continuous emission monitoring system cems chemical boiler is engineered to deliver real‑time, high‑precision data on NOx, SO₂, CO, CO₂ and O₂ concentrations directly from the flue gas stream of industrial boilers. Designed for chemical‑process facilities, power plants and large‑scale heating installations, the system enables seamless compliance with EPA, EU ETS and local environmental regulations while providing actionable insights for process optimisation.
How It Works – From Sampling to Cloud‑Based Reporting
The solution integrates a rugged probe, heated sample line, and a suite of electrochemical, infrared and parametric sensors. Once installed on the boiler stack, the probe extracts a representative gas sample, which is conditioned (temperature, humidity) before reaching the analyser. Proprietary signal‑processing firmware continuously calibrates each sensor, compensates for cross‑sensitivity, and transmits data via Modbus TCP/IP or OPC-UA to the plant’s DCS/SCADA system. A built‑in data‑logger stores 30‑day historical records, and an optional secure cloud gateway provides 24/7 remote access, alarm management and automated regulatory reporting.

Industry Certifications & Safety
Our CEMS platform is CE‑marked and ATEX‑II 3G certified for use in hazardous zones common to chemical‑boiler environments. The design complies with IEC 61010‑1 (safety of measurement equipment) and is fully compatible with the EPA 40 CFR Part 60 and EU Directive 2010/75/EU emissions standards. All electronic modules undergo ISO 9001:2015‑controlled production, and the enclosure meets IP66 protection against dust and water ingress.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom CEMS solution?
We accommodate both single‑unit pilots and full‑plant rollouts. The standard MOQ is one complete system, which includes the analyser, probe, and communication gateway. Larger projects benefit from volume pricing and dedicated engineering support.
Can the system be tailored for specific boiler capacities?
Absolutely. Sensor selection, sample‑line heating capacity, and data‑logging intervals are configurable to match boiler output from 5 MW up to 200 MW. Our OEM team works with you to define a solution that aligns with the plant’s duty cycle and emission limits.
What are the typical lead times?
Standard configurations ship within 15‑30 days after order confirmation. Custom‑engineered options, especially those requiring additional hazardous‑area approvals, are delivered in 30‑45 days depending on the complexity of the request.
Is there a warranty or after‑sales support?
All units carry a 24‑month comprehensive warranty covering parts, calibration drift, and firmware updates. Our technical support centre operates 24 × 7 with on‑site service contracts available for critical installations.
