模拟高放玻璃固化体的析晶行为

在高放废物玻璃熔制过程中,高放废物罐中心区域玻璃长时间处于高温状态,发生析晶现象。析晶增加了高放玻璃固化体的相界面,改变了其物理性质和化学性质。为了避免析晶的发生,必须研究高放玻璃固化体的析晶行为。本工作采用恒温热处理方式,研究模拟高放玻璃固化体的析晶行为。将模拟高放玻璃粉末分别在500、600、700、800、900℃下进行了0.5~96h的热处理。采用X射线衍射法(XRD)检测热处理后样品的结晶度和晶相。XRD测试结果表明:模拟高放玻璃固化体的最大结晶度析晶温度在700℃左右;热处理后产生了三类晶相辉石、斜长石和方铈矿,辉石出现在600~900℃,为主要晶相,方铈矿出现在700~900℃,斜长石只出现在700℃。

Combustion of poultry-derived fuel in a coal-fired pilot-scale circulating fluidized bed combustor

Poultry farming generates large quantities of waste. The current practice is to spread this waste onto farmland as fertilizer. However, as the factory farms for poultry grow both in numbers and size, the amount of waste generated has increased significantly in recent years. In consequence, excessive application of poultry wastes on farmland is resulting in more and more nutrients entering the surface water. One of the options being considered is the use of poultry waste as power plant fuel. Since poultry-derived fuel (PDF) is biomass, its co-firing will have the added advantage of reducing greenhouse gas emissions from power generation. To evaluate the combustion characteristics of co-firing PDF with coal, combustion tests were conducted in CanmetENERGY's pilot-scale circulating fluidized bed combustor (CFBC). The goal of this program was to verify that PDF can be co-fired with coal and, more importantly, that emissions from the combustion process are not adversely affected by the presence of PDF in the feed. The test results were very promising and support the idea that co-firing in an existing CFBC boiler firing coal is a good way to utilize PDF, resolving a potential waste disposal problem while reducing the amount of CO₂ released from the boiler.
