Possibly also "bottom ash"
There are two types of wood ash produced at the power plant, BOTTOM OR BOILER ASH, produced in the wood fired furnaces and fly ash captured in cyclones from boiler emissions
http://www.woodash.net/
Bottom Ash -- The non-airborne combustion residue from burning pulverized coal in a BOILER; the material which falls to the bottom of the boiler and is removed mechanically; a concentration of non-combustible materials, which may include toxics.
http://teachmefinance.com/Scientific_Terms/Bottom_Ash.html
For these people however, "boiler ash" includes fly ash:
Bottom Ash
Approximately 90 percent of the bottom ash stream consists of grate ash, which is the ash fraction that remains on the stoker or grate at the completion of the combustion cycle. It is similar in appearance to a porous, grayish, silty sand with gravel, and contains small amounts of unburnt organic material and chunks of metal. The grate ash stream consists primarily of glass, ceramics, ferrous and nonferrous metals, and minerals. It comprises approximately 75 to 80 percent of the total combined ash stream.
Boiler Ash and Fly Ash
BOILER ASH, scrubber ash, and precipitator or baghouse ash consist of particulates that originate in the primary combustion zone area and are subsequently ENTRAINED IN THE COMBUSTION GAS STREAM and carried into the boiler and air pollution control system
http://www.tfhrc.gov/hnr20/recycle/waste/mswca1.htm
However, "bottom ash" may be specific to waste incineration:
Bottom ash
Bottom ash is the slag or solid residue from WASTE COMBUSTION, recovered from the bottom of a furnace. A distinction is made between the bottom ash from the incineration of household waste and the incineration of hazardous industrial waste. Current regulations classify bottom ash from household waste as recyclable, treatable or storable. Recyclable bottom ash can be used for road construction under certain conditions. Bottom ash from hazardous industrial waste is treated at landfills or recycled under certain conditions

Combined ash can be divided into two varieties - Bottom ash, and Boiler ash or Flyash.

The term flyash is used to refer to the ash collected in the air pollution control system, which includes the scrubber and precipitator or bag house ash.
Bottom ash
This product can be described simply as boiler ash stream. Approximately 90 per cent of the bottom ash stream consists of grate ash which is the ash fraction that remains on the stocker or grate at the completion of the combustion cycle.

Grate ash stream consists of glass, ceramics, ferrous and non-ferrous metals and minerals.
