CI-XT100-A Coke Oven Gas Online Laser
CI-XT100-A coke oven gas online laser oxygen analysis system, after three years of market demonstration, finally has an upgraded version—CI-XT100-B! The upgraded system has the following features during use:
Zero maintenance: Shandong Laiwu Iron Steel Co., Coking Plant, Hebei Xuyang Group and many other coking plants have been running for more than five years now, we have made a major technological breakthrough, finally in this process oxygen measurement has made revolutionary progress, achieved zero maintenance!
Zero emissions: A significant improvement of this system is the realization of zero emissions. The analysis and measurement of the gas will no longer be emptied in the atmosphere as before, but will be returned to the gas pipeline again, achieving zero emissions, responding to the call of the state, being safer and greener!
It greatlyreduces the system's dependence on the water content and the water quality.
A specially designed constant pressure water washing machine has stronger decoking ability and will not be blocked!
With indirect cooling device, the cooling effect is better and the water resource is saved!
Easier to operate and use.
No need for high purity nitrogen gas as protective gas.
CI385 laser Oxygen Analyzer
The CI385 laser oxygen analyzer has high precision, fast response, long effective quasi-period, stable and reliable performance. It is one of the most advanced oxygen analyzer in the world. 0 to 25% oxygen can be measured.
The CI385 oxygen transmitter adopts SPECTRACAP® sensor technology, which is an ideal product for monitoring the oxygen content in water vapor and active gas. It is used in gas generator, inert gas, fermentation and fertilizer treatment monitoring. The measurement probe of laser measurement technology CI385 is a compact gas spectrometer with diode laser(TDL). This optical measurement technique is known for its excellent stability and high sensitivity.
The CI385 laser oxygen analyzer is an anti-hydrogen and anti-corrosion instrument, which is suitable for the determination of oxygen concentration in combustible and explosive mixed gas or air. The invention can be widely applied to chemical industry and smelting industry, such as semi-water gas and coke oven gas. detection of oxygen concentration in protective gas of semiconductor, detection of oxygen concentration in high temperature furnace; determination of oxygen concentration in animal and plant culture, vegetable and food processing and storage; It can also be used for the determination of oxygen concentration in families. the determination of oxygen concentration in vessels, underground command centers, tunnels, deep wells, civil air defense projects, and urban tunnels.
