The primary factor S which have been identified are: COAL FIRED BOILER PERFORMANCE IMPROVEMENT THROUGH COMBUSTION OPTIMIZATION Storm, R. F. and Reilly j T. Flame Refractories, Inc. Oakboro, North Carolina D. E. G. H. k. Secondary ait f IOÇ.' the burners shall be balanced within about of the mean flow.
The average improvement in unit and boiler performance is summarized in Table 3. As the results show, drier coal had a significant impact on boiler and unit performance. With drier coal, the improvement in boiler efficiency was approximately 2.6 percent. The improvement in net unit heat rate was 2.7 to 2.8 percent.
Combustion optimization of a pulverized coal-fired boiler is a complex process requiring in-depth knowledge of combustion, operation of boiler firing system and other factors affecting emissions and unit performance. For best results, combustion ... Comprehensive Approach to Performance Improvement and Emissions Reduction on a 400 MW ...
performance starts in optimizing the inputs, starting at the pulverizer. Working in coordination, Storm Technologies and SCE&G undertook a project to improve combustion, reliability and heat rate through a comprehensive mill performance improvement program, along with applying the essentials for combustion optimization.
The purpose of the present study is to bridge this gap and to improve performance and reduce related emissions in a pulverized coal combustion boiler. Therefore, a detailed numerical analysis of the effects of the three main firing configurations is carried out here using co-fired burners developed for efficient combustion.
