摘要
Abstract
The transformation and upgrading of coal-fired power units is an important means to improve their flexible,efficient,and envi-ronmentally friendly operation.It is of great significance in assisting the consumption of clean energy such as wind and solar power and achieving the"dual carbon"goals on schedule.In order to solve the problems of uneven bed temperature distribution and high initial NOx production concentration in a 2 × 300 MW circulating fluidized bed boiler of a certain power plant,a water-cooled evaporative screen and screen type reheater expansion technology transformation was implemented.After implementation,the bed temperature in the middle of the boiler significantly decreased and achieved uniform distribution,effectively reducing NOx generation and improving the flexibility of unit operation,which has good economic and social benefits.关键词
