TDLS in Waste Incinerators

O2 and HCl measurement at waste incinerators
Since this is a non-contact measurement, the measurement of exhaust gas from waste incinerators, which have a large amount of dust and corrosive components, is not problematic with TDLS™. In addition, since measurement can be performed at high temperatures, measurement and high-speed control can be realized in the vicinity of the combustion section, thereby improving the operating efficiency.

    Real-time O2 Measurement at Garbage Incinerators Improves Combustion Efficiency and Reduction in NOx and CO

 

Safety and Quality Control at Chemical Plants and Steel Works

O2 was measured for safety and quality control at chemical plants and steel works.
The TDLS eliminates the problems of maintaining sampled filters, delaying responses, and interfering gases.

 

 

Pulverized Coal Storage

O2 and CO were measured to monitor the fire prevention of coal and pulverized coal storage.
Temperature and CO-measurements are essential for detecting the ignition of coal and bag filters in storage tanks.
The reference cell can stably measure low concentrations, which were Display at 0% in other products. High-speed measurement is possible without concern of dust clogging.

 

Paper Mill

Black liquor recovery boiler in paper mill and H2S and HCl measurement in distillation kettle.
The most suitable TDLS for measuring the H2S of the exhaust gas from a soda-recovery boiler is a non-contact, sampling-free, easy-to-maintain OOC that does not require any clogging, in order to monitor the sulfur components, which is the source of the odor, and to prevent explosions. In addition, HCl in the exhaust gas of boilers using waste as fuel is also measured at high speed and accurately.

For Various Moisture Monitoring

H2O measurement for various moisture monitoring.
Measure the water content of the drying oven, such as cellophane, gypsum, plywood, paint, and food, from the % level of water to the ppm level of water in the manufacturing process, which is unpleasant.

 

 

Measured in an Electric Furnace

O2 and CO were measured in an electric furnace.
It is possible to measure the O2 and CO of the exhaust gas generated in the electric furnace and perform melting without waste.
Exhaust gas from high-temperature and high-dust electric furnaces has proven to be an installation method to suppress the effects of the exhaust gas, and can be measured without problems.
