东方300MW自然循环锅炉的调峰特性

Character of Variable Load Operation of DBC' s 300MW Nature Circulation Boiler

简要地介绍东方300MW自然循环调峰锅炉在热力性能、炉膛设计、低负荷稳燃、过热器再热器系统设计、承压部件应力分析和热工检测与控制方面的主要设计特点。东方自然循环锅炉与引进型控制循环锅炉将某些结构进行比较后表明:在调峰性能上,东方自然循环锅炉并不逊色于一些引进型控制循环锅炉。

The following main design features of the DBC' s nature circulation boiler for variable load operation are described briefly: thennal performance, furnace design, stable combustion within low olad operation, system design of superheater and reheater, stress analysis of pressure parts, thermal instrumentation and control. And a comparison of some introduced control circulation boiler.
