今年5月中旬,笔者随望亭电厂综合公司粉煤灰资源部等实地考察了波兰扎埃沙电厂,该厂向我们介绍了处理电厂粉煤灰的新专利:阿姆尔盖特。现在大多数电厂都是以烟煤为燃料,经收尘器收集后的扮煤灰,一般都是采用大量水冲灰的方法将煤灰输送到灰场。而本专利方法是在湿排粉煤灰时严格控制水与灰的比例,以高浓度的灰浆向灰场送灰,同时还向灰水中掺入某种外加剂,使粉煤灰在灰场中能自然硬化。煤灰经计量,间断下灰和加水,严格控制灰与水的比例,一般以重量比为1∶1～2.5∶1,搅拌后进入反应容器。而现传统的水冲灰的灰
In mid-May of this year, the author visited the Zaesa Power Plant in Poland with the Fly Ash Resource Department of Wangting Power Plant General Company. The plant introduced us to a new patent on handling power plant fly ash: Amberg. Most power plants nowadays use bituminous coal as the fuel. After they are collected as dust collectors, they usually use large amounts of water to transport ash to the ash yard. The patented method strictly controls the proportion of water and ash in the wet discharge of fly ash, and sends ash to the ash yard with a high concentration of mortar. At the same time, it also incorporates an admixture into the grey water to make the fly ash in the ash yard. Can naturally harden. After the coal ash is metered, intermittently lower ash and water are added, and the ratio of ash and water is strictly controlled. Generally, the weight ratio is 1:1 to 2.5:1, and the mixture enters the reaction vessel after being stirred. And now the traditional gray ash
