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.

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. No extra space is required on either side of the catalyst blocks for the structural support frame.

A shop-assembled solar receiver heat exchanger having an arrangement of heat transfer surfaces and a vertical steam/water separator structurally and fluidically interconnected thereto. A vertical support structure is provided to support the vertical separator and the heat transfer surfaces. The vertical support structure is bottom supported, while the vertical steam/water separator and heat exchanger heat transfer surfaces are top supported from the vertical support structure. The vertical support structure provides structural support and rigidity for the heat exchanger and a means by which the heat exchanger can be picked up and lifted for placement at a desired location. A fabrication/transport/lifting fixture is provided which facilitates fabrication, assembly, transportation and erection of the heat exchanger from the shop to the field. The fixture supports two trunnion shafts attached to the support structure of the receiver. Lifting lugs would be located on the top end of the support structure. Upon arrival at the job site in the field, a crane lifts the heat exchanger receiver to vertical, rotating about the trunnion shafts on the fixture, and then lifts the heat exchanger receiver for placement at a desired location.
