博爱县化肥厂于1981年又用k_4锅炉改造了一台10T/hr沸腾炉,这是继1977、1979两年先后改造两台10T/hr沸腾炉以来的第三台,经过年半多的运行和初步测定,在烧灰渣加白煤(工作质低位发热量4700～5700大卡/公斤、可燃质挥发分5～5.8％、工作质灰分22.3～33.6％)热效率为75％左右,烧纯白煤热效率达80％,负荷可调范围为5～10T/hr使用可靠。3号炉比该厂1、2号炉提高热效率10％左右,每年可节约入炉原煤1200吨,价值3万多元,采用0～6窄筛分、薄料层的操作方法,鼓风机电耗比1号炉每年节电25万度左右。下面就该厂3号炉降低能耗的主要措施、在结构和运行上有哪些特点做简单要介绍:
In 1981, Bo’ai Fertilizer Plant rebuilt a 10T / hr boiling furnace with k_4 boiler, which is the third one since its transformation into two 10T / hr boiling furnaces in 1977 and 1979. After more than a half year of operation and initial operation Determination, in the burning ash plus white coal (working low quality heat 4700 ~ 5700 kcal / kg, combustible volatile matter 5 ~ 5.8%, work quality ash 22.3 ~ 33.6%) thermal efficiency of about 75%, burning pure white coal Thermal efficiency up to 80%, adjustable load range of 5 ~ 10T / hr reliable. 3 furnace than the 1,2 furnaces to improve the thermal efficiency of about 10%, annual savings of 1200 tons of raw coal into the furnace, the value of more than 30,000 yuan, the use of 0 ~ 6 narrow screening, thin layer of operation, blower power consumption Than 1 furnace annual electricity saving 250,000 degrees. The following on the 3rd plant to reduce energy consumption of the main measures in the structure and operation of what are the features to do a simple to introduce:
