切圆 circle of contact
- 对某台200MW四角切圆燃烧煤粉炉实施了超细煤粉再燃系统的改造,并进行了现场调试试验。
A 200MW tangentially coal-fired boiler was retrofitted with a micronized coal reburning system and the performance tests were conducted subsequently. - 实际切圆直径是锅炉稳定安全运行的一个重要参数,炉膛出口残余旋转是造成烟温偏差的主要原因。
The diameter of actual tangent circle is an important parameter for safety of boiler, the residual rotation is the key factor of flue gas temperature deviation at furnace exit. - 发现合理选择容积热负荷.截面热负荷.采用分散布置的燃烧器,适当减小假想切圆直径,可以通过锅炉设计,避免燃烧神华煤的煤粉炉结焦。
It is found that the right boiler design, such as lower volume and fraction heating load and lower ideal circl.
