Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a combustion device and method for solid fuel having improved combustion efficiency, a gas heating device, a liquid heating device, a power generation system and a cooling system.SOLUTION: A combustion device 100 for solid fuel includes: a combustion furnace 20 for combusting solid fuel; and an exhaust device 42 configured to exhaust flue gas discharged from a discharge port 24 of the combustion furnace 20. When solid fuel is combusted in the combustion furnace 20, furnace pressure of the combustion furnace 20 is controlled to negative pressure of -10 Pa or less at the exhaust device 42. Between the combustion furnace 20 and the exhaust device 42, provided is a condensation unit 60 configured to condense steam contained in flue gas discharged from the combustion furnace 20. The condensation unit 60 is composed of a heat exchanger configured to transfer, to liquid or gas medium, heat generated by condensing steam.SELECTED DRAWING: Figure 2
【課題】燃焼効率が向上した固体燃料の燃焼装置および固体燃料の燃焼方法、並びに、気体加熱装置、液体加熱装置、発電システムおよび冷房システムを提供する。【解決手段】 固体燃料の燃焼装置100は、固体燃料を燃焼させるための燃焼炉20と、燃焼炉20の排出口24から排出された排煙を排気するための排気装置42とを含む。燃焼炉20で固体燃料を燃焼させている際に、排気装置42にて燃焼炉20の炉圧を−10Pa以下の負圧に制御する。燃焼炉20と排気装置42との間に、燃焼炉20から排出された排煙に含まれる水蒸気を凝縮させる凝縮部60が設けられている。凝縮部60は、水蒸気が凝縮して発生した熱を液体又は気体の媒体に移行させるための熱交換体により構成されている。【選択図】図2 |
