一种确定燃生物质锅炉的炉膛适宜出口温度的方法
摘要：
一种确定燃生物质锅炉的炉膛适宜出口温度的方法，通过生物质灰中Fe2O3、CaO、MgO、K2O、Na2O、SiO、TiO2、Al2O3的质量百分比含量计算酸碱比B/A，B/A=(Fe2O3+CaO+MgO+K2O+Na2O)/(SiO2+TiO2+Al2O3)；然后通过软化温度ST和酸碱比B/A计算炉膛出口温度T，T=ST-100+(1.0-B/A)×125。本发明具有更精细化、更准确确定适宜的炉膛出口温度的优点。
摘要（英）：

The invention provides a method for determining furnace suitable outlet temperature of a biomass-fired boiler. The method is characterized by, according to mass percentage of Fe2O3, CaO, MgO, K2O, Na2O, SiO, TiO2 and Al2O3 in biomass ash, calculating ratio of base to acid B/A, B/A= (Fe2O3+CaO+MgO+K2O+Na2O)/( SiO2+TiO2+Al2O3); and then, according to softening temperature ST and the ratio of base to acid B/A, calculating furnace outlet temperature T, T=ST-100+(1.0-B/A)*125. The method has the advantage of being capable of determining the suitable furnace outlet temperature in a more refined and accurate manner.
