摘要

以某600 ℃超超临界650 MW电站燃煤机组为研究对象

结合650~700 ℃超超临界电站煤粉锅炉的总体方案

以NH

替代部分燃煤

对NH

与煤在锅炉中混合燃烧进行了模拟研究。探究了不同NH

混燃比下炉膛内温度、物质分布规律

以及不同混燃比和NH

喷入方式对NO

排放的影响。结果表明:随着NH

混燃比增加

炉膛中心火焰温度明显降低

高温区域减少

炉膛内火焰温度整体呈下降趋势

这主要是因为NH

理论火焰温度较低

因此会延长低温射流

着火延迟;在NH

喷口位置NH

浓度达到峰值

随着燃烧进行

基本被消耗完

在炉膛出口不会出现氨逃逸现象;在空气分级燃烧下

炉膛主燃区域O

浓度低

有利于NH

还原反应的发生;随着NH

混燃比增加

炉膛出口NO

排放浓度降低

这是由于炉膛内NH

会和NO发生还原反应

抑制了NO的生成;在NH

以不同方式喷入炉膛时

发现使用油枪喷口喷入时炉膛出口NO

浓度较低

这是因为油枪喷口位置更靠近主燃区。

Abstract

Taking a coal-fired unit of a 600 ℃ ultra supercritical 650 MW power plant as the research object

combined with the overall plan of the coal-fired boiler of the 650-700 ℃ ultra supercritical power plant

the simulation study was conducted on the mixed combustion of NH

and coal in the boiler by replacing part of the coal with NH

.The temperature and mate

rial distribution of NH

in the furnace at different mixing ratios

as well as the effects of different mixing ratios and NH

injection ways on NO

emissions were explored. Results show that as the NH

mixing ratio increases

the flame temperature at the center of the furnace decreases significantly

the high-temperature area reduces

and the flame temperature inside the furnace shows an overall downward trend

this is mainly due to the lower theoretical flame temperature of NH

which prolongs the low-temperature jet and causes the delay of ignition. At the NH

nozzle position

the NH

concentration reaches its peak. As combustion progresses

is basically consumed

and there will be no ammonia escape at the furnace outlet. Under air staged combustion

the low oxygen concentration in the main combustion zone of the furnace is conducive to the occurrence of NH

reduction reaction. As the NH

mixed fuel ratio increases

the NO

emission concentration at the furnace outlet decreases

which results from the reduction reaction between NH

and NO in the furnace

inhibiting the generation of NO.When NH

is sprayed into the furnace in different ways

the NO

concentration at the furnace outlet is lower when using the oil gun nozzle for injection. This is because the position of the oil gun nozzle is closer to the main combustion zone.
