摘要
研究了高浓度有机废液和混煤废液的燃烧特性和动力学参数,考察其着火特性、燃烧燃尽特性、动力学参数以及燃烧特性对有机废液焚烧炉设计、运行等的影响。研究表明:高浓度有机废液粘度低,具有良好的雾化特性;其热值较低,使得着火温度较高;混煤有机废液较原有机废液易着火,且燃烧稳定、良好,燃尽时间也较短。
Investigation emphases were combustion characteristics and dynamics parameter of high concentration organic wastewater and wastewater mixed with coal, in allusion to survey its ignition characteristics, burn-off trait, dynamics parameters and its influence on design, operation of organic wastewaer incinerator. The results of thermobalance mechanism experiment shown that high concentration organic wastewater＇s viscosity was low with favorable flow and atomization performance, while its ignition temperature was high owing to low heating value. Wastewater mixed with coal contains some inflammable constituents and sodium-base compounds promoted combustion reaction, which were ascended as the mixture proportion growing. As a result, it was easier to catch fire than high concentration organic wastewater with excellent inflammation and short burn-off time.
