PROCESS FOR REFORMING THE FLY ASH AND APPARATUS THEREFOR

A process for reforming the fly ash, including the heating step that heats a raw fly ash powder containing the unburned carbon at a temperature of 780 to 1000 C. to decrease the amount of the unburned carbon contained in the raw fly ash powder; the classifying step that introduces the heat-treated fly ash containing the unburned carbon in decreased amounts obtained through the heating step into a classifying apparatus in the state of being heated at a high temperature so as to separate the fly ash into a coarse powder and a fine powder; the fine powder recovering step that recovers the fine powder of the heat-treated fly ash obtained through the classifying step by using a dust-collecting apparatus; and the milling step that mills the coarse powder of the heat-treated fly ash obtained through the classifying step until a 45 m sieve residue becomes not more than 34% by mass, and then recovers the milled powder.

Circulating fluidized bed boiler with a loopseal heat exchanger
10890323 · 2021-01-12 · ·

A circulating fluidized bed boiler is described, comprising a furnace, a loopseal, and a loopseal heat exchanger arranged in the loopseal. The loopseal heat exchanger comprises walls limiting an interior of the loopseal heat exchanger, a first particle outlet for letting out particulate material from the loopseal heat exchanger, an inlet for receiving bed material, heat exchanger tubes arranged in the interior of the loopseal heat exchanger, and a first ash removal channel configured to let out ash from the loopseal heat exchanger. An ash cooler is configured to receive ash from the first ash removal channel. In the loopseal heat exchanger the first ash removal channel is arranged at a lower level than the first particle outlet.

EXPANSION PIPE JOINT AND INCINERATION ASH TREATMENT FACILITY

An expansion pipe joint that absorbs displacement occurring at a connection portion between an upstream pipe and a downstream pipe includes an outer tube having a downstream end coupled to the downstream pipe, an inner tube that is inserted into the outer tube and has an upstream end coupled to the upstream pipe, and a closing member having elasticity that is provided between an upstream end of the outer tube and the upstream end of the inner tube so as to close a gap between them. Then, a difference between a position in an axial direction of the upstream end of the outer tube and a position in the axial direction of the upstream end of the inner tube is within a predetermined range so that a bus line of the closing member is inclined from the axial direction.
