NDIR MULTI GAS ANALYZER

Component Flue Gas Analysis System Technology Transfer Program

Patent Equipment

The infrared multi - component flue gas analysis system is a multi - gas natural gas analyzer based on NDIR - nondispersive infrared sensor. The technology can continuously monitor a variety of parameters in the same instrument, such as CO, CO2, NOX, SO2, CH4, C6H6, NH3, VOCs, HCL, etc. The device probe is specially designed, durable, and can be used for high concentration flue gas monitoring. It has a high accuracy of measurement results, there is no sample conditioning, it's easy to use and has significant cost savings and low operating costs.

Market Demand & Application

The main application areas for the industrial plant and, industrial pipe dust pollution monitoring, industry covers electricity, cement, oil refining, chemical, pulp and paper and other facilities.

Future Monitoring Parameters That May Be Raised

R & D experts can also use NDIR (such as the Sick MCE model) to further develop SO3 monitoring in the future, but may require heating of the probe / heated multi-vias as an extraction analyzer, using the same design (90%). But the current SO3 part has not yet been completed. Any future medium IR gas monitoring such as hydrocarbons (800 to 5000 cm -1 wavenumber), N2O, NH3, HCl, HF, SO3, etc. can be achieved on the machine.

Technology Transfer Schedule

Technology Transfer Schedule: When the buyer is ready to sign the contract, the transfer of technology can begin. Within six months, it can be produced at the buyer's facility.

How the Equipment Works

The infrared multi-component flue gas analysis system can be used for on-line analysis of up to five gas phase components.

The instrument is based on the dual wavelength infrared principle, where the specific wavelength of the infrared radiation beam is transmitted through the optical head unit. Part of the beam is then measured by the gas composition, through the principle of quantitative real-time monitoring of the original measured gas components and content.

By using a pair of collimated optics to achieve a "straight path" design, the infrared beam can be extended to a longer distance while detecting a low level of gas concentration with minimal energy loss. It also has the flexibility to change the insertion length of the optical probe. The insertion length is critical for simultaneous sampling of representative in situ measurements of a series of emissions. Therefore, you can use the same hardware, without any design changes, significant savings in capital and operating expenses.

Features

  • Multi-component flue gas analysis: Only a single measuring tube can measure up to five parameters
  • Direct in situ measurement: No high cost, high maintenance sample handling system is required
  • Built-in filter: dust can not enter the optical element - to avoid the frequent cleaning of the inconvenience
  • Automatic zeroing, automatic cleaning: Reduces the calibration frequency and eliminates the risk of condensation when the heater lens is faulty.
  • Heat the sample probe: Effectively prevent optical condensation (only when the flue gas continues to be below the dew point)
  • Incandescent filament Infrared light source: low cost, easy to replace
  • Ballet single moving components: Maximize data reliability and reduce errors
  • Anti-vibration optimized design: Improves optical accuracy and reduces noise effectively
  • Signal Processor Unit Trends: Factory performance and emissions monitoring at a glance.
  • Flue gas trend data One-click printing: Easy to archive
