System and method for pre-startup or post-shutdown preparation for such power plants are disclosed which are subject to frequent startups and shutdowns, such as a solar operated power plant. The system and method introduces an auxiliary fluid flow to be circulated in an opposite direction to a direction of normal working fluid flow responsible for producing electricity. That is, if the working fluid flow in a first direction for operating the power plant, than the auxiliary fluid flows in a second direction, opposite to the first direction. The auxiliary fluid flows in the second direction for a predetermined time and at a predetermined conditions through a plurality of superheater panel arrangements of solar receiver former to activation of the working fluid circuit, as pre-startup preparation of the power plant, and after cessation of the working fluid circuit, as post-shutdown preparation of the power plant, to attain predetermined conditions in the superheater.

A material feed apparatus for influencing the travel properties of a feed stream of material moving between a pulverizer and a furnace includes a feed path passing through an upstream passage periphery UPZ. The feed path includes one duct A having a branch entry A and another branch duct C having a branch entry C both downstream of the upstream passage periphery UPZ through which the feed stream of the material travels in two segregated portions. A Y-axis drive assembly and the X-axis drive assembly move the nozzle relative to the reference axis RA, whereupon the upstream passage periphery UPZ moves relative to the reference axis RA such that the travel properties of the one portion of material in the one branch duct A are different than its travel properties before the movement of the upstream passage periphery UPZ.
