We designed an extremely custom high-pressure, high-temperature steam exhaust fan for this emerging green energy technology application. The fan needed to handle very high temperatures up to 1300°F. For that, we used a stainless steel fan casing/housing, a special multi-carbon ring shaft seal, a monobloc bearing assembly with mist oil lubrication, an alloy 625 rotor with a special design for stresses induced by static, dynamic, and thermal loads. We also machined mounting surfaces for the bearing assembly and motor drive.

We delivered a custom high-temperature, high-pressure fan for a heat recovery steam generator (HRSG) application. Designed for temperatures as high as 840°F, the fan has a carbon ring shaft seal, a monobloc fan bearing assembly with oil lubrication, exterior fan insulation, and a raised access door with a flush interior design for the exterior insulation.
