未被点燃的

When the temperature of smoke inpouring air preheater increases, aggregate fuels and sediments will combust in stated temperature conditions.

这些起火起因于燃料油的不充分燃烧，其结果是未充分燃烧的燃料油凝结和聚集在空气预热器的部件上，当进入空气预器的烟气温度增高时，沉积的燃料油被烘烤，当达到一定温度条件时，则可点燃这些燃料油污沉积物，造成火灾发生，这通常被称为空气预热器的二次燃烧。

From simulations and data of fire site, most air preheater fire often appear when boiler is started in cool state and standby which fuels of insufficient combustion coagulate and congregate on the parts of air preheater. When the temperature of smoke inpouring air preheater increases, aggregate fuels and sediments will combust in stated temperature conditions. It is called the second combustion of air preheater.

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
