2results about How to "Prevent high temperature corrosion" patented technology

The embodiment of the invention provides a high-temperature heat storage-supercritical steam generation system. The high-temperature heat storage-supercritical steam generation system comprises a heat storage body, a supercritical steam generation unit connected with the heat storage body and an intelligent control unit connected with the supercritical steam generation unit. The heat storage body comprises a solid waste-based graded porous carrier and fused salt filled in gaps of the solid waste-based graded porous carrier; the supercritical water vapor generating unit comprises a water vapor generator with a built-in spiral metal pipe and a multi-stage heat exchange runner; the intelligent control unit comprises a digital controller, an axial-flow compressor and a heat exchange pump, the digital controller is connected with the axial-flow compressor, the heat exchange pump and the heat storage body, and the digital controller is configured to dynamically adjust the running states of the axial-flow compressor, the heat exchange pump and the heat storage body.

This invention provides a method for constructing refractory bricks. The refractory bricks are installed onto L-shaped hooks pre-installed on a water-cooled wall. Filler is then placed between adjacent refractory bricks, and finally, self-flowing castable refractory is poured between the refractory bricks and the water-cooled wall. This method allows the refractory bricks to be fixed to the side of the water-cooled wall in contact with flue gas (i.e., the heat exchange surface) using hooks. This not only prevents high-temperature corrosion of the water-cooled wall by flue gas but also effectively ensures the heat exchange efficiency of the water-cooled wall and extends its service life.
