Name: ABB EL3020 | Continuous Emission Monitoring System (CEMS) Gas Analyzer - Runsheng Automation
SKU: ABB EL3020

Description

The ABB EL3020 is a state-of-the-art modular online process gas analyzer, specifically engineered for Continuous Emission Monitoring Systems (CEMS) and complex industrial process control applications. Designed to meet stringent environmental regulations like the HJ 75-2017 ultra-low emission standards, this unit provides real-time, high-precision measurement of key pollutants including sulfur dioxide (SO₂), nitrogen oxides (NO/NOx), carbon monoxide (CO), and carbon dioxide (CO₂). By integrating advanced sensor technologies into a single robust platform, the EL3020 ensures that power plants, cement kilns, and steel mills can maintain compliance while optimizing combustion efficiency.At the heart of the ABB EL3020 lies a sophisticated dual-measurement technology fusion. It utilizes Non-Dispersive Infrared (NDIR) absorption principles to detect polar molecules like CO, CO₂, and SO₂ with exceptional selectivity, while simultaneously employing electrochemical sensors for precise oxygen (O₂) and NOx measurement. This hybrid approach allows the analyzer to handle a wide dynamic range of gas concentrations, from ppm-level trace detection in clean processes to percentage-level measurements in heavy industrial flue gases. The system features automatic range switching, ensuring data continuity even when emission levels fluctuate rapidly.Beyond its sensing capabilities, the ABB EL3020 is built for durability in harsh environments. The sampling probe is constructed from corrosion-resistant titanium alloy with ceramic filtration, capable of withstanding high temperatures and abrasive dust loads. Internally, the analysis unit employs a two-stage Peltier cooling system to precisely control sample gas dew point, effectively removing moisture interference without losing soluble gas components. With support for ABB Ability™ digital services and AI-driven drift compensation, the EL3020 represents a significant leap forward in automated environmental monitoring, reducing maintenance overhead and ensuring data integrity.

Main Features and Advantages

Dual-Technology Precision:
The primary advantage of the ABB EL3020 is its ability to combine NDIR and electrochemical technologies within a single chassis. The NDIR module uses a specialized optical bench with a long path length to detect minute gas concentrations with high signal-to-noise ratios. Simultaneously, the electrochemical cells provide reliable oxygen background monitoring. This combination eliminates the need for multiple separate analyzers, significantly reducing the footprint and complexity of your CEMS shelter or cabinet.Robust Sample Pre-treatment:
Industrial flue gas is often hot, wet, and dirty. The EL3020 addresses this with a rugged sample conditioning system. It features a heated sampling line option to prevent acid condensation during transport and a high-efficiency Peltier cooler to dry the gas before it enters the analysis cell. This “cool-dry” method protects the sensitive optics from corrosion and fouling, extending the service life of the instrument in aggressive environments like waste incineration or coal-fired boilers.Intelligent Diagnostics and AI:
Modern automation requires smart devices. The ABB EL3020 includes comprehensive self-diagnostic protocols that monitor light source intensity, detector health, and filter status. The 2023+ firmware iterations introduce AI algorithms based on LSTM neural networks to automatically correct for cross-interference between gases (e.g., CO₂ interference on CO readings). Furthermore, the unit supports remote configuration and data aggregation via ABB Ability™, allowing central control rooms to manage fleets of analyzers without dispatching technicians to the field.Flexible Modularity:
Whether you need a single-component monitor or a full multi-gas solution, the EL3020 adapts to your needs. Its modular architecture allows for the hot-swapping of optical benches and sensor modules. If your regulatory requirements change—for instance, adding ammonia (NH₃) slip monitoring for an SCR DeNOx system—you can upgrade the hardware and software configuration without replacing the entire analyzer chassis.

Application Field

Thermal Power Generation:
In coal and gas-fired power plants, the ABB EL3020 is critical for Flue Gas Desulfurization (FGD) and Selective Catalytic Reduction (SCR) monitoring. Located at the stack inlet or outlet, it measures SO₂ and NOx concentrations to ensure the plant operates within its permitted emission limits. The fast response time (<3s) allows the DCS to adjust limestone slurry dosing or ammonia injection rates in real-time, preventing over-consumption of reagents and avoiding costly environmental fines.Cement and Lime Production:
Cement kilns present a challenging environment with high dust loads and variable process conditions. The EL3020, equipped with its heavy-duty titanium probe and ceramic filters, withstands these abrasive conditions. It monitors CO levels to optimize the combustion of alternative fuels (like tires or biomass) and tracks NOx to manage the thermal stress on the kiln refractory, ensuring both operational safety and product quality consistency.Steel and Iron Manufacturing:
In the metallurgical sector, process gas analysis is vital for energy recovery. The ABB EL3020 analyzes the calorific value of blast furnace gas and converter gas by measuring CO and CO₂ content. This data helps operators balance the gas distribution network, routing valuable fuel gas to boilers or turbines rather than flaring it. Additionally, continuous monitoring of toxic gases like CO in the ambient air of the facility ensures worker safety.Waste Incineration:
Incinerators must strictly control emissions of acidic gases and incomplete combustion products. The EL3020 provides the necessary accuracy to monitor HCl, HF, SO₂, and CO. Its ability to handle corrosive acid gases makes it a preferred choice for wet scrubber control loops, where maintaining the pH of the scrubbing liquid depends directly on the real-time acid gas load measured by the analyzer.

Installation and Maintenance

Pre-installation preparation:
Installing the ABB EL3020 requires careful planning of the sampling location. Ensure the probe insertion point is representative of the average gas flow and accessible for maintenance. Verify that the mounting surface can support the weight of the analysis cabinet (approx. 15-21kg per module) and that the ambient temperature does not exceed 45°C without additional air conditioning. Connect the power supply (100-240V AC) using shielded cables to prevent electromagnetic interference, and ensure the grounding resistance is less than 4 Ohms to protect the sensitive electronic components.Maintenance recommendations:
To ensure the longevity of the ABB EL3020, regular maintenance of the sample conditioning system is mandatory. Replace the ceramic probe filters and PTFE tubing filters according to the pressure drop alarms or every 3-6 months in high-dust environments. Check the蠕动 pump (peristaltic pump) tubing for wear and replace it annually to ensure effective condensate drainage. Perform a zero and span calibration monthly using certified standard gases to verify the linearity of the NDIR optical bench. Additionally, inspect the Peltier cooler’s heat sink for dust buildup, which can reduce cooling efficiency and lead to water vapor entering the gas cell.
