Abstract
In a process to limit the production of flyash by dry bottom boilers, flyash is collected from flue gas using a collector such as an electrostatic precipitator. The collected flyash is carried in a carrier gas stream to which a fuel is added. The stream is introduced into the boiler in a manner to cause the flyash to soften, agglomerate and fall into the bottom ash pit.
