In-Situ NOx/O2 Monitor: INM-700

HORIBA's INM-700 in-situ gas analyzer is designed to meet the requirements of coal-fired power generation plants for cost-effective, low maintenance NOX monitoring. The analyzer uses a ceramic diffusion filter and Zirconium Oxide sensor directly in the gas stream, which eliminates the need for an extraction process for sample collection, and results in lower maintenance. The INM_700 is ideal for inlet SCR control, NOX measurements, and burner balancing/combustion tuning in boiler plant operations.

The INM-700 has the advantage of lower installation, maintenance and capital costs, and a faster response time. In addition, for compliance stratetgies, the ceramic filter allows measurements to be taken near the combustion point of the furnace. This technique utilizes combustion modification techniques such as:

• Low NOX burners (LNB)
• Over-fire air injection (OFA)
• Gas re-burn systems
• Boiler tuning
• Combustion optimization programs

Instrument Features:

• A NOX sensor using a new technology for coal fired applications which can improve control of the ammonia injection rate in SCR systems.
• A practical NOX sensor with a fast response time that can be directly installed in the combustion gas stream.
• Extremely robust sensors that are long lived and capable of withstanding elevated temperatures.
