Title:

PRESSURIZED FLUIDIZED FURNACE EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2014/156356

Kind Code:

A1

Abstract:

In the present invention, the following are provided: a fluidized bed furnace (1) for pressurizing combustion air (B) and combusting a material to be treated (A) while fluidizing the same; an air preheater (3) for exchanging heat between a combustion exhaust gas (C) discharged from the fluidized bed furnace (1) and the combustion air (B); a dust collector (4) for removing dust from the combustion exhaust gas (C); and a first and second supercharger (5, 6) to which the combustion exhaust gas (C), having undergone heat exchange in the air preheater (3) and dust removal in the dust collector (4), is supplied to generate compressed air (D, E). The first compressed air (D) generated in the first supercharger (5) is supplied as the combustion air (B) to the fluidized bed furnace (1) by way of the air preheater (3), and the second compressed air (E) generated in the second supercharger (6) is given a higher pressure than that of the first compressed air (D). The present invention thereby makes it possible to prevent an excess of equipment although a plurality of first and second superchargers are provided, and to make efficient use of the surplus combustion exhaust gas.
