ABSTRACT:
A composition including exfoliated vermiculite and ash produces a soft clinker deposit. In a method to remove ash deposits from furnace structures, vermiculite is added to the gases and ash produced during a combustion process and combines with the ash forming deposits. The vermiculite-ash deposit is softer than a pure ash deposit and can be removed by the application of jets of steam to the furnace structures. An apparatus, used to preheat and inject vermiculite into furnace structures, includes a housing having walls defining a passage. The housing has a distal portion for projecting into containment vessel holding combustion gases and a proximal portion for receiving hot gas under pressure. The passage within the proximal portion includes a narrow section, a tapered section and a wide section. The tapered section has an opening for communicating with a source of vermiculite and for withdrawing the vermiculite as high velocity hot gas is directed into the narrow section, through the tapered section and out the wide section by a venturi effect. The vermiculite mixes with the hot gas as the vermiculite and hot gas exit through the wide section of said proximal portion and out the distal portion of the housing.
