Abstract

The embodiment of the invention provides a water vapor generator. The water vapor generator comprises an evaporator plate and a heat exchange structure, and the heat exchange structure is connected with the evaporator plate. Water flows into a communicating flow channel from an inlet flow channel, and heat is supplied to the evaporator plate through the heat exchange structure, so that the water is boiled, vaporized and evaporated into water vapor on the evaporator plate. Evaporation flow channels can slow down pressure fluctuation through the parallel connection mode that the first ends of the adjacent evaporation flow channels communicate with one another, and the second ends of the adjacent evaporation flow channels communicate with each other, enough expansion volume can be reserved for vaporization, and communicating vessels can slow down pressure fluctuation caused by different flow resistances due to different boiling states generated at the same moment in different parallel evaporation flow channels. The communicating vessels play a role in pressure relief and pressure redistribution, and the pressure difference between the different evaporation flow channels in the evaporator plate is reduced, so that the pressure and flow fluctuation of an inlet and an outlet of the whole water vapor generator is relieved.

Description

technical field [0001] The invention relates to the technical field of steam generation, in particular to a steam generator. Background technique [0002] Water vapor plays a very important role in the SOFC power generation system, which is mainly manifested in: the ratio of water vapor and carbon in the gas stream entering the reformer is a key factor in reforming; the stable water vapor and carbon in the fuel stream entering the fuel cell The ratio can prevent carbon deposition and prolong the life of the SOFC system; the pressure and flow of water vapor will affect the change of combustion components in the downstream burner and affect the stable operation of the burner. Therefore, maintaining the stability of the water vapor flow rate and precisely controlling the ratio of water vapor to carbon are important considerations in the design of water vapor generators in SOFC systems. [0003] In the steam generator in the prior art, during the boiling process of the liquid f...
