BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a configuration diagram illustrating a power generation system using molten waste heat generated in the production of mineral fibers according to the present invention. FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to one embodiment of the present invention, as shown in Fig. 1, a first eco-meter (not shown) for heating a working fluid of a first working fluid line 15 using molten waste heat supplied from a molten waste heat supplying section 1 (20) for passing molten waste heat from the first econoverter (10) through the water chain (22) to remove heavy metals and for discharging the heat medium steam (24) A second econ omizer 30 for heating the working fluid of the second working fluid line 35 by using the heating medium steam 24 of the water chain precipitation tank 20, First and second steam turbines 11 and 31 that are driven by steam of the first and second clutches 15 and 35 and are interlocked with the generator 50 through the first and second clutches 12 and 32, (13, 33) for condensing the working fluid recovered from the first and second steam turbines (11, 31) through the first and second condensing heat exchangers (13, 33) ) From It is configured to be opened by hand-printing hand-printing supply pipe 40 for the supply to the hand-printing settling tank 20. The

At this time, the molten waste heat supply unit 1 is a waste heat source that is generated in the course of liquefaction and liquefaction of wastes such as bottom ash and fly ash in an electric furnace, a charcoal furnace, etc. together with coke- And the exhaust gas is collected and supplied to the molten waste heat.

Here, the first economizer 10 is a waste heat recovery apparatus for heating the working fluid of the first working fluid line 15 by using the molten waste heat supplied from the waste heat supply unit 1, To supply the fluid to the first steam turbine (11).

The molten waste heat discharged from the first economizer 10 is supplied to the water chain precipitation tank 20 by the waste heat supply pump 16 through the water chain water supply pipe 40 When the molten waste heat of the first eco-nomiator 10 is supplied to the water-stranded water, the particles such as various heavy metals mixed in the molten waste heat are precipitated as the water-chain slurry 23, The purified molten waste heat is raised while forming bubbles, and at the same time, the water chain water is heated and vaporized to form the heating medium steam 24 so as to be filled in the compressed state on the upper part of the water chain precipitation tank 20 Consists of.

At this time, the water-chain slurry (23) precipitated in the lower portion of the water-chain precipitating tank (20) is configured to be discharged to the outside through a slurry discharge pipe (21)
