【摘要】 本研究在现场调研的基础上,探讨了火电厂脱硝工程液氨罐区环境风险最大可信事故,初步确定了最大可信事故的类型及源强计算参数。并以此为基础,以不同液氨管径的电厂为例进行了环境风险预测,给出了300~600MW机组液氨泄漏风险最大可信事故发生后的半致死浓度距离,对火电厂液氨的环境风险评价具有一定的参考价值及现实意义。更多还原

【Abstract】 This study discussed the maximum credible accident of the environmental risk of denitration project in ammonia storage tank of thermal power plant based on site survey,and initially identified the type of maximum credible accident and the calculation parameter of source strength. Based on these,this study had predicted the environmental risk of thermal power plants in different liquid ammonia pipe sizes,provided the distance of LC50 under the ammonia leakage occurrence of 300 MW to 600 MW units,and had certain reference value and practical significance for the environmental risk assessment of liquid ammonia in thermal power plants.更多还原
