Circulating fluidized bed boiler low nitrogen combustion technology
circulating fluidized bed boiler as a new power generation equipment,circulating fluidized bed boiler can burn coal as fuel and have significant effect of energy saving and environmental protection,has become one of the most practical of the clean coal combustion technology currently,has been rapid development. ZG in order to improve the circulating fluidized bed boiler combustion optimization of the cleaning effect, has made breakthrough progress in control technology in low nitrogen.
At present, the progress of technology and the capacity of circulating fluidized bed boiler in China increase, domestic CFB boiler will gradually play a positive role in China's electric power production and environmental protection, ZG circulating fluidized bed boiler combustion technology in low NOx is mainly reflected in the reduction of NOx combustion emissions, specific measures in:
1.One or two wind layout optimization method: one or two wind layout optimization can improve the grade of air, which can not only strengthen the oxidation zone and reduction zone hypoxia burnout piecewise low NOx combustion effect, but also inhibit the temperature and the temperature at low nitrogen level, and high efficiency combustion of a high degree of unity.
2.Flue gas recirculation technology: the use of flue gas recirculation technology, an oxygen content of air is reduced to 17% to 19%, while maintaining the flow of state, strengthen the staged combustion furnace, and further promote the circulation of the fly ash amount inside and outside of the furnace, so that the bed temperature decreased, have beneficial effects on the low nitrogen and high desulfurization process.
3.Measurement and control system: by measuring the precise flow can achieve the following main purpose and effect of the secondary air flow can be measured: one or two; one or two wind can be adjusted accurately, the staged combustion can be precisely controlled; combined with the flue gas CEMS, can realize the closed loop adjustment; can keep unit in low nitrogen condition; coordination control the combustion efficiency of nitrogen oxide and boiler.
The low nitrogen combustion technology, the circulating fluidized bed power plant boiler can not only solve the S02 emission concentration is high, combustion instability, easy fire shooting, low load performance is poor, but also can make another kind of pollutants emissions of --NOx gas boiler flue gas in power plant to reduce the 80% to 90%, reduced the pollution of boiler smoke to atmospheric environment effectively, protect the ecological environment have great significance.
