To gain a detailed understanding of the application of wear-resistant ceramics in thermal power plants, it is necessary to understand the specific equipment used in thermal power plants;
After initial crushing, coal blocks from thermal power plants are made into coal powder in coal mills, which is transported to boilers through pipelines for combustion and power generation; The involved wear and tear equipment, coal mills, powder conveying and coal dropping pipelines (expansion joints), as well as silos and hopper chutes. Please provide a detailed introduction to the porcelain pasting process of the equipment in order;
Coal mill: Taking the medium speed coal mill as an example, the parts with high wear include the cylinder body and separator. The position 1.5m above the feed inlet of the cylinder body is called the bottom of the cylinder body. This position has high wear, high temperature, and impact, and requires high impact wear resistance of ceramics. It is recommended to use camel hump style welded ceramic plates and bond them with high-temperature glue; The upper part of the cylinder is mainly worn by coal powder, with almost no impact. It is recommended to use ordinary welded ceramic plates; But the thickness cannot be less than 15mm; 5mm mosaic ceramic can be used for the position of the separator, which is bonded with high-temperature adhesive. Due to the inverted cone shape of the separator, if the ceramic is not firmly attached, it may fall off, and a professional construction team is required for construction;
Powder conveying pipeline and coal dropping pipeline: Different ceramic styles are selected for powder conveying pipelines according to the size of the pipeline. For pipelines with a diameter of DN250 or more, ceramic tiles with a thickness of 8-8-10mm can be used, while for pipelines with a diameter of DN250 or less, mosaic tiles can be used; Due to slight vibrations, the coal chute requires the use of welded ceramics, and special attention should be paid during construction;
For silos, hoppers, chutes, etc., ceramics can be selected according to actual working conditions,
