FREE VALVE brand pneumatic ceramic lined valves have been installed at Duyen Hai Power Thermal Plant Project in Vietnam since the year 2020.

In recent years, the application of ceramic materials is very active in petroleum, chemical industry, machinery , the using ceramic wear resistance, corrosion resistance instead of metal materials to produce wear-resistant, corrosion resistant parts ,which is one of the important development direction of high-tech materials market.

Ceramic double disc gate valve is mainly divided into straight stroke ceramic double disc gate valve and Angle stroke ceramic double disc gate valve ( ceramic rotary double disc gate valve), these two kinds of valves are widely used on pipeline of fly ash system in the coal power plant, the valve is mainly driven by pneumatic actuators, open and close quickly.

Ceramic double Gate discharging valve has good sealing performance, but after using it for a long time, there will be problems, how to solve it?

Pneumatic conveyor is driven by the compressed air, transporting the powder material from on end of the sealing vessel to another end. The applied industry is widely

Coal-power plants create large quantities of ash from the burning of the coal. Electrostatic precipitator systems(ESP systems) can effectively recycle fly ash, to purify the gas .Lightweight and Small, particles are known as fly ash because they rise with the stack gasses.

FGD (Flue gas desulfurization ) is a process which absorb SO2 as well as other contaminative gas by lime stone slurry in the power plant , by the same time it can produce the lime gypsum slurry by product .
