Provided is a cooling water spray apparatus including a plurality of spinners disposed to be adjacent to one another along a travel path of a target to be cooled, and a plurality of cooling water spray holes provided on each spinner and configured to spray cooling water. The plurality of spinners may be non-overlappingly disposed with respect to one another.

A fossil-fuel power generation system assisted by waste incineration includes a waste incineration subsystem and a fossil-fuel power generation subsystem; wherein: the waste incineration subsystem includes a waste incinerator and the fossil-fuel power generation subsystem includes a main boiler; a flue gas channel is provided between a furnace of the waste incinerator and the main boiler; flue gas generated by waste incineration of the waste incinerator enters the main boiler through the flue gas channel; and the flue gas channel is located in a low part of the main boiler. Based on a high-temperature combustion environment of the main boiler, thermal energy of combustible waste is fully released and a thermal efficiency is increased; moreover, the flue gas discharged by the waste incinerator contains harmful substances which are mostly burned down by a high-temperature incineration of the main boiler. A secondary incineration greatly reduces the harmful substances and protects environment.

In order to efficiently remove deposited material adhering to the interior of an abatement device, an abatement device is equipped with a deposited material removing means for removing deposited material produced during abatement of exhaust gas. The deposited material removing means includes: a storage unit that stores a liquid; a gas supply unit that supplies pressurized gas to the storage unit; and a valve that sprays a mixed fluid of the liquid stored in the storage unit and the gas supplied by the gas supply unit.

A fluidized bed gasification furnace includes a control device that identifies a defective fluidization spot of a fluidized bed based on distribution of temperatures detected by a plurality of temperature sensors, temporarily increases an amount of supplied combustion gas to air boxes located below the identified defective fluidization spot, and increases a speed of discharge of noncombustibles and a fluidization medium discharged by an extruder.

A system and process for disposal of dry fly ash that effectively confines and damps fugitive dust during the collection, sorting, transporting, storage and treatment of fly ash at a landfill. The system and process for disposal of dry fly ash utilizing an enlarged, oversized hopper positioned at the top of a hill and an elongate channel that runs between the enlarged hopper and the landfill. A bulk transport truck hauling a belly dump trailer dumps dry fly ash through an elevated platform having a centrally aligned orifice into the oversized hopper having a slurry rack and a large hopper grate. The ramps and raised platform of the enlarged hopper allow the belly dump trailer compartments to be closer to the orifice and the hopper grate in order to minimize fugitive ash during the disposal process.

Remote submerged scraper conveyor (SSC) consists of a conventional SSC modified to include a slurry processing system, which allows it to be located remotely from associated boilers at or slightly above grade level rather than directly under a boiler like a conventional SSC. The slurry processing system includes a pair of overflow troughs 34 and associated weirs located exterior to and along the top edge of each side of the horizontal section of the SSC and an underflow baffle, which extends from a position above the water line down into the horizontal section of the SSC below the water line. The slurry processing system allows the Remote SSC to receive a high volume wet ash slurry discharge via a slurry discharge pipe conventionally sent to an ash pond or a tall dewatering bin system.
