Abstract

The invention relates to a hot area structure of an MW-level solid oxide fuel cell power generation system. The hot area structure comprises a heat insulation shell, a two-section air preheater, a desulfurizer, a steam generator, a pre-converter, a reformer, a combustor and corresponding gas pipelines. The hot area structure is large in fuel handling capacity, small in hot area space and compact in internal device arrangement, meanwhile, achieves fuel treatment, air preheating, tail gas treatment and waste heat utilization and meets the requirements of the MW-level solid oxide fuel cell power generation system adopting natural gas, methane, marsh gas and the like as fuel; an anode tail gas recycling process is adopted, so that the fuel utilization rate is improved, the water-carbon ratio is reduced, and the electric efficiency and the thermal efficiency of the SOFC power generation system are favorably improved; and the two-section air preheater is adopted, the air preheater high-temperature section and the air preheater low-temperature section of smoke are fully utilized, the smoke exhaust temperature is effectively reduced, and it is guaranteed that air at the cathode inlet of an SOFC cell stack reaches the proper temperature.

Description

technical field [0001] The invention relates to the technical field of solid oxide fuel cells, in particular to a hot zone structure and an operation method of a MW-level solid oxide fuel cell power generation system. Background technique [0002] Solid oxide fuel cell (Solid Oxide Fuel Cell, referred to as SOFC) is a fuel (such as natural gas, H 2 , synthesis gas, biogas, methanol, etc.) chemical energy directly into electrical energy efficient power generation device. Compared with the traditional power generation technology, the SOFC power generation system has a wide range of fuel sources, high power generation efficiency, no NOx emissions, and can realize CO 2 Concentrated emission and other advantages. As a new type of high-efficiency and environmentally friendly power generation equipment, SOFC system has broad application prospects in the distributed power supply fields of residential, hotel, hospital, school, office buildings, communities, data centers, communicat...
