High Pressure Product Chamber: Typical ash coolers operate at ambient pressure inside the product chamber but recent developments in boiler design often require product chamber pressures of 300 psig or higher. Therma-Flite Holo-Scru® ash coolers can be manufactured with jacketed tubular housings, and equipped with patented Shaft Rider Seals to maintain product chamber pressures of 300 psig or higher. This design can also incorporate a clam shell housing for ease of inspection and maintenance.
Large Diameter Multi Screw Ash Coolers: Larger boiler designs require larger ash handling capacities. Often single screw designs just can’t handle the required capacity. Therma-Flite Holo-Scru® ash coolers can be manufactured in single, twin and quad screw configurations with rotor sizes from 8 to 48 inches in diameter.
Replaceable Inlet Troughs:Therma-Flite Holo-Scru® ash cooler is water jacketed to increase the cooling capacity. The inlet section is manufactured as a removable section that can quickly be removed and replaced, reducing repair time and cost.
