XPTC has Class A qualification certificate of power equipment cleaning issued by former Ministry of Power with 40 years experience in boiler and condenser chemical cleaning of power plant. With sufficient high-tech engineers and technicians XPTC has strong capacity of R&D and engineering execution. Human resources structure is: 5 Senior Chemical Cleaning Engineers including 2 Professor Senior Engineers, 15 engineers, 35 technicians, 14 engineering teams with more than 300 workers. Professor Senior Engineer Chen Jie is the major author of Chemical Cleaning Guideline Of Power Plant Boiler DL/T794-2001. Specialist Yang Zhenqian and Senior Engineer Zhang Quangen are responsible for edit of Chemical Cleaning And Filming Guideline Of Power Plant Condenser. XLG and XLN series mobile chemical cleaning stations for boiler and condenser were developed based on long term engineering practice, featuring in complete functions and simple operation which was awarded the Best Technical Achievement Prize of Shaanxi Power Group and patent certificate of China. The benefit of the products are excellent reliability, security and efficiency.
More than 20 mobile chemical cleaning stations are used in XPTC for boiler, condenser and ash sluicing pipe cleaning in 12 to 900 Mw power plant according to different requirement of pressure, temperature, flow and concentration. The equipments have been used in more than 200 projects in about 100 power plants from year 2000.
Comparison between old and new technology
|
|
All equipment installed on site (old method) |
Mobile station system (new method) |
|
1 |
Heavy workload, high cost, low efficiency, low quality |
Low workload, Low cost, High efficiency, high quality |
|
2 |
Long period for temporary system installation |
Much shorter time (only 3-5 days depends on system) to be used for temporary system installation |
|
3 |
More defects and leakages |
Reliable operation without leakage |
|
