Abstract

The invention discloses a methane vapor reforming unit, comprising a reforming heat exchange apparatus, a methane conveyer pipe and a vapor conveyer pipe, and a preheating chamber. The reforming heat-exchange apparatus comprises a reforming chamber and a high temperature channel. The methane conveyer pipe and the vapor conveyer pipe are communicated with the reforming chamber and pass through the preheating chamber. The high temperature channel passes through the reforming chamber. The methane vapor reforming unit also has a preheating chamber. The preheating chamber can preheat the methane and the vapor needed for the reforming, thereby shortening the time of heating the methane and the vapor in the reforming chamber and enabling the methane and the vapor in the methane vapor reforming unit to have relatively higher reforming efficiency.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a steam methane reforming device; the invention also relates to a solid oxide fuel cell power generation system using the steam methane reforming device. Background technique [0002] The solid oxide fuel cell power generation system is a new type of power generation device, which belongs to the third generation of fuel cells. Chemical power plant. [0003] Solid oxide fuel cell power generation system is an energy conversion device that converts fuel from chemical energy into electrical energy and thermal energy. Its high efficiency, pollution-free, and all-solid-state structure have made it one of the most important energy conversion tools with the most potential. . Solid oxide fuel cell power generation systems have great advantages in terms of fuel efficiency, emissions, maintenance and noise pollution. There are many reforming devices that provide the required hydroge...
