摘要
为配合干熄焦余热锅炉 (CDQ锅炉 )的开发和制造 ,保证CDQ锅炉过热器受热面管子在含焦粉粒的烟气中长期安全使用 ,通过试验 ,采用超音速火焰喷涂NiCr -Cr3 C2 粉末对受热面管子表面进行喷涂加工 ,确认涂层各项性能及指标满足设计要求。为后续的CDQ锅炉制造作了技术准备 ,现制作的首台CDQ锅炉已投入使用 。
In order to cooperate with the development and fabrication for the CDQ type boiler and to assure the safe running of all heating surface of tubes of CDQ boiler super heater in the gas with coke powder for a long time, NiCr-Cr 3C 2 powder is deposited on heating surface of the tubes by using HVOF spraying method. The resalts show that all properties of coating are satisfied with the design requirements ,and also make good technical preparation for following CDQ boilers .Now the first CDQ boiler already have been put into practice and also gained good result .
