摘要： A thermal power plant that uses low-grade coal as fuel and allows for increased thermal efficiency of the entire plant is provided. The thermal power plant includes a drying device (3) that dries the low-grade coal to be supplied to a lignite mill (coal pulverizer) (4), and a drying-gas heater (13) that heats air to be supplied to the drying device (3) so as to be used for drying the low-grade coal. A condenser (12) and the drying-gas heater (13) are connected with each other via a heat exchanger (19), and exhaust heat from the condenser (12) is used as a heat source for heating the air.

摘要： In a porous filter (10A), dust that has been collected from a gas through a filter group installed in a vessel body (12) onto filter surfaces is removed from the filter surfaces by backwashing in which the supply and stoppage of a high-pressure gas ejected toward porous filter elements 14 are repeated by means of a valve operation. Backwash tanks (42) having upstream backwash valves (38) and downstream backwash valves (40) are installed in backwash pipes (32) through which the high-pressure gas is guided from high-pressure-gas supply equipment (30) to backwash nozzles (34) for ejecting the backwash high-pressure gas toward the filter group to form a backwash high-pressure-medium supply line. The outlet pressure of the high-pressure-gas supply equipment (30) is set to "1 / critical pressure ratio" or more times a filter inlet gas pressure so that the flow speed of the high-pressure gas ejected from the backwash nozzle (34) is the speed of sound.

摘要： The reliability of backwashing valves constituted of first backwashing valves and second backwashing valves is ensured. A first backwashing valve (backwashing-gas rear valve) (7) that controls gas for backwashing and a second backwashing valve (backwashing-gas front valve) (6) that operates at slower speed than the first backwashing valve (7) are disposed, in a series including two or more thereof, at backwashing-gas introducing pipes individually provided for each of the filter blocks.

摘要： There is provided a slag discharging system having high flexibility in layout and capable of stable slag discharge in low cost with high reliability. The slag discharging system is configured to rapidly cool slag (S), discharged by producing combustible gas in a gasification furnace (1), within cooling water into glassy slag (S), collect the slag (S) along with the cooling water discharged out of a system of the gasification furnace (1) into a slag reservoir (21), and thereafter convey the slag (S) from the slag reservoir (21) to a slag storage tank (13); and this slag discharging system includes a slag slurry tank (23) for collecting the slag (S) from the slag reservoir (21) into water so as to make the slag into slurry therein, slag slurry piping (25) for making a connection between the slag slurry tank (23) and the slag storage tank (13), and a pump (27) so disposed in the slag slurry piping (25) as to suck the slag slurry within the slag slurry tank (23) and feed the slag slurry to the slag storage tank (13).
