Pulverized Coal Injection (PCI) is a process that blowing large volumes of fine coal granules into the blast furnaces. This process provides a supplemental carbon source to speed up the production of metallic iron, and reduce the need of coke production. Therefore energy use and emissions also can be reduced. However, high speed coal powders will cause serious abrasion to the pipe fittings and valves. Especially for the valves, once the valve trims were damaged, the normal operation of the PCI system will be seriously affected.
However when Foyo’s full lined ceramic ball valves are installed In Pulverized Coal Injection system, abrasion was no longer a problem. High hardness and excellent mechanical properties ensure Foyo’s ceramic ball valves have a long-term and trouble-free operation.
FOYO FCBV series forged ceramic ball valve uses ceramics ball and lining. When applying to strong acid, strong alkali, slag, powder, grain, slurry, and other high-temperature, high corrosive and abrasive working condition, our ceramic ball valves have stable working performance and longer service life than metal seated ball valves no matter as on-off valves or flow control valves.
FCBV series forged ceramic ball valve is three-pcs body design with flange connection. Material of body could be carbon steel or stainless steel according to working conditions or per customers' requirements. All wet parts include ball, seat and lining are all made of structure ceramics so that medium will not be in touch with body directly and valve body will not be corroded or abraded.
Three pieces design of FCBV series forged ceramic ball valves could make sure of flexible assembling dimensions. Flange dimensions and face to face of valves could be designed per customers' special requirements, so that ceramic ball valve could be assembled on the pipeline without any modification of current pipe and salve assembling cost.
All trims of valves (including ball, seats, bushing, lining and stem, etc) have been precisely designed and machined to make sure that body of valve will not be in touch with medium directly and body of valve will not be corroded or abraded by medium. Sealing faces of ceramic ball and ceramic seats have been polished by advanced technique and machines. After precise grinding, all leakage level of FCBV series forged ceramic ball valves could reach ANSI/FCI 70-2 Class VI(zero leakage).
Actuation of FCBV series valves includes lever, bare stem, worm gear, pneumatic actuator and electric actuator, etc. Mounting pad is designed according to ISO 5211.
>99%Al2O3, ZrO2, Si3N4, SSiC are made by Cold isostatic pressing molding and high sintering. All these ceramics will not interact with almost all organic solvent and inorganic chemical medium (except hydrofluoric acid), so ceramics will not contaminate medium. Solid Tungsten carbide( STC) has good mechanical performance and thermal-shock performance, which is suitable for high temperature, high pressure and high abrasive working conditions.
Structure ceramics has wonderful chemical stability, which makes sure that physical property and chemical property of ceramic trims will not change after long times of usage in all kinds of strong acid and strong alkali.
FOYO FCBV series forged ceramic ball valves have showed great performance in various severe highly corrosive working conditions of steel mill, metallurgy, Petro-chemical, mining, coal-fired power plant, paper & pulp, polysilicon, etc.
FOYO's experienced engineers will select the most suitable material and solution for different working conditions.
