The project uses a limestone-gypsum wet desulfurization process and is equipped with an online continuous monitoring system for flue gas. During the construction of the project, the company conscientiously implemented the “five-system†management with the project legal person responsibility system as the core, and thoroughly summarized and learned the lessons learned from the desulfurization project under construction, overcoming the short equipment delivery cycle, the narrow construction site and tight construction period. Strictly control the safety, quality and progress of the project. On December 9, 2006, it successfully passed the 168-hour full-load trial operation. The company boldly innovates and innovates the working methods and methods, and creatively adopts the plum blossom welding lining process to solve the difficult problem of anti-corrosion treatment of the inlet flue of the absorption tower, and creates a new anti-corrosion construction process; in the design project, the participating units jointly Explore and boldly use domestically produced equipment to replace imported equipment, optimize design concepts, and accumulate valuable experience for further localization of desulfurization equipment.
By the end of 2006, all the units of the company had achieved desulfurization, and the desulfurization efficiency was over 96%, which was higher than the design value of 95%. Only one phase can reduce sulfur dioxide emissions by 18,000 tons per year, which promotes the improvement of atmospheric environmental quality.
Automobile Oxygen Sensor is a key feedback sensor in the control system of electric injection engine. It is also a key part to control automobile exhaust emission, reduce automobile pollution to environment and improve the quality of automobile engine fuel combustion. The oxygen sensor is installed on the engine exhaust pipe.
Application: Cars
Q: How do I know the O2 sensor is good or not?
A: The only way to know if the O2 sensor is functioning normally is to check its responsiveness to changes in the air/fuel mixture, by Voltage Measurement or Waveform Simulation.
Use a 10-megaohm digital voltmeter. Hook up the voltmeter's red probe to the sensor's signal wire and the black probe to engine ground. (Use back probe method, DO NOT pierce the wire.) For a good sensor, voltage should fluctuate constantly between 0.1 and 0.9 volts after starting the engine for 2 or 3 minutes.
