An air preheater water jet apparatus is provided for cleaning fly ash, soot and the like from a rotating or stationary heat exchange basket on a air preheater used to improve the efficiency of a boiler in an electric utility generating plant. The air preheater cleaning apparatus includes a cleaning assembly with water jet nozzles, thereon, attached to a carriage which moves along a track, such as a channel beam, affixed radially above and adjacent to the air preheater basket. A drive assembly and an idler bracket assembly with a roller chain therebetween are disposed on the channel beam. The carriage assembly is attached to the roller chain and as the carriage is driven, the cleaning assembly is moved along the channel beam. Thus, when the basket, or the air preheater cleaning apparatus, is rotated and the carriage is moved inward, a circular path of the basket is cleaned. Additionally, a variable speed motor control apparatus is used to increase the air preheater rotational speed as the carriage assembly moves inward, such that the relative speed between the cleaning assembly and the air preheater basket remains constant as inward movement occurs.

An integrated control system, specifically transportable on water between offshore wells, includes mixing and blending subsystems, a pumping subsystem, a proppant subsystem and a control subsystem for controlling the other subsystems in a unified manner from a common control location.

A compact, transportable apparatus includes test equipment for operating on a sample of slurry within a single container to determine the compressibility, thickening time, and static gel strength of the sample. The static gel strength test is particularly performed with a load cell vertically moved along a lead screw, which load cell is directly connected to a drive mechanism for driving a paddle at a very slow speed through the sample.
