在稻草、麦草、玉米秸杆、棉花秸杆、玉米芯、棉籽壳、稻壳等等可再生生物质能源资源中,目前唯有稻壳已开发出商业性用途。我国的稻壳资源非常丰富,每年产稻谷近200Mt,可获得稻壳约40Mt,折合为标准煤约20Mt。在南方各个省份,把稻谷作为燃料已历史久远。近些年来,燃烧稻壳的装置已逐渐从土炉灶、技术落后的手烧炉发展成为 1t/h、2t/h、4t/h 甚至10t/h 的正规的链条炉排锅炉,如湖南省的常德、江苏省的盐城等地都有定型的稻壳锅炉。然而,目前稻壳锅炉炉型基本上是
Of the renewable biomass energy resources such as straw, wheat straw, corn stover, cotton straw, corn cob, cotton seed hulls and rice husks, only rice hulls have been developed for commercial use. China’s rice husk resources are very rich, with an annual output of nearly 200 Mt rice, about 40 Mt rice husks, equivalent to about 20 Mt of standard coal. In various southern provinces, using rice as fuel has a long history. In recent years, the device for burning rice husk has gradually evolved from a soil oven and a technologically backward hand furnace into a regular chain grate boiler of 1t / h, 2t / h, 4t / h and even 10t / h, Changde, Yancheng, Jiangsu Province and other places have stereotypes of rice husk boilers. However, the current husk boiler type is basically
