自1977年开始,我厂为富拉尔基发电总厂、通辽发电厂、长山热电厂设计、制造了燃烧褐煤的670t/h 锅炉。富拉尔基发电总厂燃用扎赉诺尔褐煤,通辽发电厂与长山热电厂燃用霍林河褐煤。两种煤虽然同属褐煤,但是,扎赉诺尔褐煤的水份大,达34.63%,而霍林河褐煤的灰份较高,达32.88%。由于煤质的差异,造成锅炉设计结构的不同。两种煤的共同特性是发热值低、易结焦、对锅炉受热面的磨损严重。两种煤的工作质特性见表1,煤灰特性见表2。 Since 1977, our factory has designed and manufactured a 670 t / h boiler for burning lignite for the Fulaerji Power Plant, Tongliao Power Plant and Changshan Thermal Power Plant. Fulaerji Power Plant burning Zharanuoer lignite, Tongliao Power Plant and Changshan Thermal Power Plant burning Huolinhe lignite. Although both types of coal belong to lignite, Zhalainuoer lignite has a large moisture content of 34.63%, while Huolinhe lignite has a higher ash content of 32.88%. Due to differences in coal quality, resulting in different boiler design structure. Common characteristics of the two coal is low in calorific value, easy to coke, serious wear on the heating surface of the boiler. The quality characteristics of two kinds of coal in Table 1, coal ash properties in Table 2.
