Metal wear is one of the main reason behind boiler tube leaks.
Metal wear leaking pipe explosion occurred mainly in the economizer, low temperature super heater, reheater. Economizer is one kind of high dense tube banks which have a high glue gas flow
rates. If the furnace smoke contains more ash particles or in the process of shipment boiler. Due to the incomplete combustion of pulverized coal in the stove leaving a lot of smoke and ran aft, will exacerbate the wear rate of the economizer. Low temperature super heater and low temperature re heater wear generally occurs in the local position of the furnace tube by the slope of
the wall. Through the wall portion of the pipe, pipe elbow, pipe and comb card contact area, meal ware and tear are likely to exist.
