XG-40/3.82-M Acceptance of brickwork quality

1. Once the brickwork is finished, the user should organize the professional personnel to check and accept the brickwork quality according to the national relative standards.
2. After inspection, the wear-resistant material manufacturer should supply the boiler-baking curve and boiler-baking program.
3. The combustion shell in the under-bed ignition burner is suggested to be installed on site. And after baking with woods, it could be finally located.
Attachment: meaning explanation of some important physical and chemical indicators of furnace wall material
Thermal shock resistance: it means the capacity of the refractory products which resist the rapid temperature changes without cracking or peeling off. Measure it with the times that it is repeated heated or cooled without damages.
Compressive strength: it means the maximum pressure which is bore by unit area, and it is marked with the symbol “MPa”. And there are different catalogues like the room-temperature compressive strength, drying compressive strength, high temperature compressive strength and the after-burning compressive strength. And they reflect the mechanical properties of products under variety use cases, and it is an important technical indicator of the measuring of quality and performance.
Rapture strength at high temperature: The limited bending stress on unit area which is bore by products under high temperature. It means the ability to resist bending or breaking under high temperature, and it is marked with the symbol “MPa”.  
Notes:
The wear-resistant material quality and the brickwork quality of CFB boiler are very important. It is one of the key factors which relates to boiler’s long-term, safe and reliable operation. It can be done well if the user, the installation unit and the brickwork unit pay great attention to. And it is proved that if the wear-resistant material and the brickwork are of good quality, the boiler operation can be safe and reliable, and it should be lasted for a long term.
About the selection of the anti-wear materials, the design of furnace wall structure and the requirements of brickwork, please always contact with our designers, together we can improve the quality of brickwork.
