Pulverized Coal Flow Control Valve

The pulverized coal flow control valve, also known as pulverized coal angle valve, is installed between the pulverized coal feeding tank and the gasification furnace in pulverized coal gasification process units such as shell, GSP, HT-L, and CHOR, and is a key device for control the flow of pulverized coal entering the gasification furnace and accurately controlling the oxygen-coal ratio in the gasification furnace. This flow control valve in pneumatic valves and controls system has the performance that directly to the realization of safe and long-term stable operation of the gasification furnace.

Pulverized Coal Flow Control Valve Technical Specification

Size: From DN50 up to DN80

Body material: Carbon steel, Stainless steel

Trim materials: Stainless steel (std.)

End connections: Flanged

Max rating: ANSI 900


Pulverized Coal Flow Control Valve Sturcture Fearture

The medium transported by the pulverized coal control valve is solid pulverized coal particles with a certain hardness and takes high-pressure nitrogen or carbon dioxide as a carrier, and is a gas-solid two way flow control valve. As the concentration of the pulverized coal in the medium is higher, a larger chance of the concentration of the pulverized coal is easily caused in the adjusting process, the pulverized coal is easily accumulated, bridged, and blocked so that the flow is unstable, and the pulverized coal is easily leaked and combusted. When the in line flow control valve works, high-speed moving pulverized coal particles cause great scouring to the group valve, so that the pulverized coal flow is unstable or even the adjustment is invalid, and the motorized flow control valve is required to have comprehensive performances of high-pressure resistance, scouring resistance, abrasion resistance, stable flow regulation, and other comprehensive performance.
