Our continuous emission monitoring system for hydrogen boiler provides real‑time, high‑precision measurement of NOx, CO, CO₂, and residual hydrogen in flue gas streams. Designed for industrial‑scale hydrogen‑fired boilers, the solution integrates seamlessly with existing DCS/SCADA platforms, delivering the data needed to meet stringent environmental regulations while optimizing combustion efficiency.

Engineered for durability in high‑temperature, corrosive environments, the unit features IP66‑rated housing, explosion‑proof wiring, and modular sensor cartridges that can be swapped without shutdown. Whether you operate a power‑generation plant, a chemical processing facility, or a hydrogen refueling hub, this monitoring system safeguards compliance and supports continuous improvement initiatives.

How It Works

The system combines a heated sampling line, a dual‑laser absorption spectrometer, and a rugged PLC controller. Sample gas is drawn continuously through a temperature‑controlled probe, eliminating condensation and ensuring consistent optical path length. The spectrometer performs non‑dispersive infrared (NDIR) and tunable diode laser absorption spectroscopy (TDLAS) to quantify each constituent with sub‑ppm accuracy.

Data is processed on‑board, applying temperature and pressure compensation algorithms validated against ISO 17025 standards. Results are streamed to the plant’s control network via Modbus TCP, OPC UA, or proprietary protocols, with optional edge‑analytics for trend‑based alarm management. The modular architecture allows additional sensors (e.g., SO₂, VOC) to be added as future compliance needs evolve.

All values are typical for standard installations. Custom sensor suites, extended temperature ranges, or dedicated hazardous‑area certifications can be engineered on request.

Application Scenarios

• Power plants converting natural gas to hydrogen for low‑carbon electricity generation, where continuous NOx and CO monitoring is mandated by regional emission permits.
• Industrial furnaces using 100 % hydrogen fuel to melt steel, requiring real‑time hydrogen slip detection to protect downstream equipment.
• Hydrogen refueling stations equipped with on‑site boilers for water heating; the system verifies that residual hydrogen stays below safety thresholds.
• Research facilities testing new combustion strategies; the modular sensor platform supports rapid re‑configuration for experimental gases.

In each case, the continuous emission monitoring system for hydrogen boiler reduces compliance risk, enables automatic emissions reporting, and provides the data foundation for fuel‑optimisation algorithms that lower operating costs.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for a custom‑configured unit?

We accept single‑unit orders for prototype or pilot projects. For full‑scale production, the typical MOQ is 5 units, which allows us to optimize component sourcing and reduce lead‑time.

Can the system be integrated with existing DCS/SCADA software?

Yes. The unit supports Modbus TCP, OPC UA, and Ethernet/IP out of the box. Custom drivers for proprietary protocols are also available under a separate integration contract.

What is the typical lead time from order to shipment?

Standard configurations ship within 15‑30 days after receipt of a purchase order and payment. Complex, highly‑customized solutions may require 45‑60 days, depending on component availability.

What warranty and after‑sales support are provided?

All units carry a 24‑month limited warranty covering manufacturing defects and sensor calibration drift. On‑site calibration service, remote diagnostics, and spare‑part logistics are offered through our global support network.
