Background:


Pulverized coal injection (PCI) method was developed in the 19th century,

The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the mid-bottom inlet of a blast furnace, then mixed with secondary hot air (termed the "blast") supplied through a blowpipe in the tuyere and then piped to a furnace to create a balloon-like cavity called a "raceway", which then propagates coal and coke combustion and melts the solid iron ore, releasing molten iron. The most remarkable aspect of this method is that it allows for cheaper coal to be consumed in the system, replace expensive coke, thereby remarkably cutting down on costs. Because of the severe environment inside the furnace, (>2000K), visual observation of raceway shape and size is impossible, therefore remotely measuring sensors are used to investigate the chemical and physical reactions inside the furnace.


However, the high speed pulverized coal powder is very abrasive, pepe fittings and valves are essily to be worn. Especially the sealing face of the valves. leakage will cause big failure of the system. When advanced ceramics are used for valves in pulverized coal powder system, things were become much better. 


The hardness of  pure >99% alumina ceramics and high strength zirconia ceramics is more than HRA 88, much harder than coal powder. Technical engineers from FOYO have much experience in PCI system in steel plant, the disign and structure of FOYO ceramic ball valves are optimized and improved specially for PCI system. 

On the other hand, Foyo has powerful technical team and can respond quickly to user requirements. we developed DIN/EN standard full lined ceramic ball valves for customers all over the world.

DIN/EN Standard Ceramic Ball Valves for PCI System

It has been proved that Foyo's full lined ceramic ball valves for PCI system have excellent stability and reliability锛?more than 5 times service life than commen metal seated ball valves锛?even longer, which reduce much maintenance time and cost.

Customerized flange and face-to-face dimension is optional.
