听力原文：Hello, NicolE.This is William. Hope everything is going well in Port Chester. I'm in Albany now. I'm calling for two reasons: first, to let you know that I'll be in Port Chester on the twenty-ninth. I'll be taking the train down from Albany. Which leads me to my second point: do you think you or someone could pick me up at the Croton train station? I just looked at the train schedules and I realized that to get to Port Chester from Albany, I would have to go down to Penn Station in Manhattan and then back up to Port Chester from Grand Central Station. It would be great if I could avoid that extra time and travel. If not, I'll manage, but please give me a call on my cell phone when you have a chance and we can figure it out. Thanks.

F热电厂2x300MW扩建工程的燃煤输送系统包括：煤仓，运煤系统，破碎系统和给煤系统。煤仓内堆煤最大高度为14m。燃煤由汽车运人电厂，采用带式输送机将煤送到磨煤机中磨成煤粉，煤粉送至锅炉喷燃器，由喷燃器喷到炉膛内燃烧。扩建工程使用该厂原有的2个容积500m3柴油储罐储存点火锅炉用燃油。给水系统的功能是将水送人省煤器。进人省煤器的水经水冷壁和过热器等受热面，变成过热蒸汽后送入汽轮机带动发电机发电。F厂调节水系统有1个储存为12t的液氨储罐。发电机的冷却方式为“水--氢--氨”方式，氨气由直径100mm的管道引人发电机设备中。制氢系统有9个表压3.2MPa、容积10m3的氢罐，锅炉机组最大连续蒸发量为1025t h，过热蒸汽出口压力为17.75MPa。F厂远离城区，为方便员工生活，F厂在厂区内设立了1座加油站，加油站有2个容积150m3的汽油储罐，汽油的密度为730kg m3。受F厂委托的安全评价机构E对该厂扩建工程进行了安全评价，出具了安全评价报告，并提出了安全生产标准化建设方案。[问题1]为预防燃煤输送系统事故，应采取哪些安全技术措施？[问题2]F厂委托给E机构的安全评价属于哪种类型？简述该类安全评价包括的主要内容。
