The present invention provides a steam generation apparatus using a solid fuel, the apparatus comprising: a solid fuel supply part for supplying a refuse-containing solid fuel; a solid fuel transport part for transporting the solid fuel supplied from the solid fuel supply part from one side to the other side, and continuously pyrolyzing the transported solid fuel using a heat source supplied from outside; a discharge part for discharging, to the outside, residue which has been continuously pyrolyzed while passing through the solid fuel transport part; a gas transport part for collecting and transporting pyrolysis gas generated when the solid fuel was pyrolyzed while passing through the solid fuel transport part; a burner part for combusting using the pyrolysis gas supplied through the gas transport part; and a steam generation part for generating steam using a heat source generated from the burner part. Thus, by pyrolyzing the refuse-containing solid fuel in the solid fuel transport part by means of the low-temperature heat source, the solid fuel may be recycled, and steam is generated in the steam generation part using the pyrolysis gas generated during the pyrolysis, and a portion of the generated steam is supplied to the solid fuel transport part so that same may be used for pyrolyzing the solid fuel, and thus energy efficiency may be increased, and costs may be reduced.

Abrégé
There is provided a suspended combustion type power steam generator capable of rapid and high-temperature pyrolysis using FRDF for extending residence time of high-temperature gas, and particularly the present invention improves the heating conditions of fluid in an arch water pipe, a heating water pipe and a down pipe by extending the residence time of high-temperature gas inside a combustion chamber. The present invention is an improvement of a power steam generator using fine refuse derived fuel (FRDF) which is an alternative energy source, and a flameless combustion device using fossil fuel capable of structuring a new additional facility so as to address the possibility of irregular raw material supply in the ethyl alcohol fuel operation for new renewable energy, that is, FRDF. Therefore, fuel conversion operations can be carried out and a circulation path is partially restructured so as to prevent the interruption of the natural convection function of boiler water regardless of FRDF operation or fossil fuel operations. The existing power steam generator is commonly used in 0.5 tons class and has the problem of having a short residence time of high-temperature gas according to the heating conditions of fluid in a large capacity power steam generator of 5 tons or higher. The present invention extends the residence time of high-temperature gas in the combustion chamber by installing a baffle plate portion so as to sufficiently satisfy the heating condition of fluid as the result.
