阅读说明:本技术 减少包括热交换器的焚烧炉的所述热交换器的腐蚀的方法 (The method for reducing the corrosion of the heat exchanger of the incinerator including heat exchanger ) 是由 约瑟夫·扬·彼得·比尔曼 于 2018-03-26 设计创作,主要内容包括:减少焚烧炉的热交换器的腐蚀的方法,所述方法包括以下步骤:-将含氧气体和颗粒燃料引入至燃烧室中,-将包括i)粘土和ii)碳酸钙的添加剂材料引入至焚烧炉中,-使用热交换器从烟气中回收热量。为了保护热交换器,添加剂材料是被引入至热交换器上游的烟气中的粉末状材料,所述粉末状添加剂材料的粉末颗粒包括细粒,每个细粒包括粘土和碳酸钙的混合物,相对于碳酸钙按重量计至少10%是以下形式的碳酸钙:当在氮气气氛下以10JC每分钟的升温速率借助于热重分析表征时,当达到875℃的温度时该碳酸钙已经完全分解。(The method for reducing the corrosion of the heat exchanger of incinerator, it the described method comprises the following steps :-oxygen-containing gas and granular fuel are introduced in combustion chamber, to include i) clay and ii) additive material of calcium carbonate is introduced in incinerator ,-using heat exchanger heat is recycled from flue gas.In order to protect heat exchanger; additive material is the dusty material being introduced into the flue gas of heat exchanger upstream; the powder particle of the powdered additive material includes particulate; each particulate includes the mixture of clay and calcium carbonate; be the calcium carbonate of following form relative to calcium carbonate by weight at least 10%: when being characterized in a nitrogen atmosphere with 10JC heating rate per minute by means of thermogravimetric analysis, when reaching 875 DEG C of temperature, the calcium carbonate decomposes completely.)
