Yiyuan Thermal Power Plant has two low-rate buried-tube furnaces with differential beds, which were put into operation in 2005. Buried-tube is arranged in dense phase zone. Buried-tube is washed directly by burden, resulting in frequent tube burst. From July 2015, the power plant began to use the laser cladding boiler tubes of Beijing Huadian De Hi-tech Co., Ltd. After several maintenance shutdown cycles, on February 26, 2018 again shut down to check, cladding layer almost no wear.

After the meeting, technicians from various power plants visited the wear and tear of buried pipes by laser cladding in 21 # furnace.

The application effect of laser cladding wear-resistant products of Beijing Huadian De Hi-tech Co., Ltd. in Yiyuan buried-tube boiler with serious thermal and electrical wear has been highly recognized by the experts attending the meeting. The laser cladding high temperature wear-resistant technology is an excellent measure to effectively solve the local severe wear of boiler.
