Pressure bearing container of heat accumulating type heater

Abstract

The invention discloses a pressure bearing container of a heat accumulating type heater. The pressure bearing container meets the mounting, fixing and connecting requirements of refractory materials,it is guaranteed that the pressure bearing container works within the allowable temperature range, thermal stress damage in the working process is avoided, the structure supporting and positioning structure in a shell is clear, construction is convenient and fast, airflow circulation and uniformity are effectively guaranteed, and thermal stress gathering in the long-time oven drying process is prevented. The pressure bearing container comprises an outer shell, a fuel gas outlet three-way companion flange, a high-temperature air outlet companion flange, a combustor companion flange, a water cooling jacket assembly, a temperature measuring flange and a bottom supporting structure, wherein the fuel gas outlet three-way companion flange, the high-temperature air outlet companion flange, the combustor companion flange, the water cooling jacket assembly and the temperature measuring flange are arranged on the outer shell, and the bottom supporting structure is arranged in the outer shell andused for bearing a heat accumulator and a heat insulation layer.

Description

technical field [0001] The invention relates to a pressure bearing container, in particular to a pressure bearing container used for a regenerative heater, which can be applied to a high-temperature pure air test system directly connected to a scram press test bench and other regenerative heater systems. Background technique [0002] The basic working principle of the regenerative heater is: heat the regenerative material with high-temperature gas, heat the temperature of the regenerative material from normal temperature (300K) to 2000K, then turn off the high-temperature gas, let air in from the bottom, and use the regenerative material to cool the air Heating from room temperature (300K) to above 1800K. [0003] The development and application of regenerative heaters abroad are mainly concentrated in the United States (such as NASA, ASE Corporation and AEDC), France and Japan (NAL), etc. As early as the 1960s and 1970s, the United States ASE began the development of such h...

[0007] The second is to provide a transitional expansion section for the normal temperature and high pressure test air to expand from the small flow area to the heat storage body circulation channel during the pressurization stage and the official working stage. The flow field shape of the normal temperature and high pressure air at the inlet directly affects the air flow in the heat storage body. The heat transfer results will have a great impact on the results of the entire test
