Quartz sand
Incineration of municipal and industrial sludge in fluidized bed furnaces.
Successful reconditioning of service-proven metal-seated ball valves for high-temperature applications contributes to optimized CAPEX and OPEX for the customer. Municipal and industrial sludges are incinerated in a fluidized bed furnace (incinerator).
The quartz sand used in this process keeps the material to be incinerated in motion. To discharge the quartz sand, ball valves INTEC K231-S-HT-FM/11-S of nominal size DN100 and pressure rating PN16 with a stem extension are used. The discharge of the very abrasive quartz sand takes place at a slight negative pressure and at temperatures of 700°C to 800°C.
Features of the ball valve
- trunnion mounted design with spring-loaded ball seat on one side and a free outlet on the other side (absolutely free of dead space and unobstructed media outflow)
- ball and ball seats are manufactured with hard metal coating of chromium carbide nickel/chromium using the HVOF process (High Velocity Oxy-Fuel spraying)
- body is made of high-temperature material 1. 4828 (stainless heat-resistant austenitic chromium-nickel steel)
- spring chamber of the ball seat is sealed
