Abstract

See full text

An overhead catalyst loading device eliminates the need for lower flanges of the overhead catalyst structural support frame or dedicated overhead trolley beams to prevent ash build up collecting on a selective catalytic reactor (SCR) reactor box and provides an advantageous electric hydraulic lifting mechanism suitable for integration into a SCR device. The overall width of the SCR device is reduced since the structural support frame in the SCR device fits in the gaps between catalyst blocks. The overhead electric hydraulic catalyst loading device also minimizes the chance of injury during catalyst block installation by using an electric hydraulic actuated lifting mechanism consisting of spacers and structural telescopic members which may comprise holes and pins for height adjustment to allow for loading and unloading catalyst blocks into and out of a SCR device. Methods of lifting and loading and unloading a catalyst block are also presented therein.
