对喷流协同蒸汽相变对燃煤细颗粒脱除性能的影响
Removal of Fine Particles From Coal Combustion by Combined Impinging Streams and Heterogeneous Condensation
摘要
Abstract
The removal of fine particles from coal combustion was investigated experimentally based on impinging streams and heterogeneous condensation,with electrical low pressure impactor and Vaisala-HMT337 type temperature and humidity sensor.The influence of the operating parameters on fine particles removal efficiency was analyzed.The experimental results show that increased addition amount of steam and velocity of flue gas brings higher removal efficiency.An increase in horizontal gap between the opposing impinging causes an increased collect efficiency firstly,but then decreased.The mesh demister mounted at the top of the heterogeneous condensational growth chamber has better performance in removal particles than corrugated plate demister.Removal efficiency can be effectively promoted by adding volatile wetting agent glycol to flue gas,but not distinct by adding isooctyl alcohol or ethylenediamine.Fine particles can be removed effectively by adopting the combined impinging streams and heterogeneous condensation technology.关键词
