Chain grate boiler is a large industrial boiler used in Industry and providing concentrated heating . This type boiler is with the feature of low failure rate, double drum water capacity, high safety factor, and the technology has developed very mature now. However,it is still has some problems during the use and the operation. The problem of chain grate boiler 1, If the differential pressure increases, and the pump inlet pressure drop, may be a filter block, should be opened the bypass, the filter remove clean. 2, circulating pump anomalies (1) when the current of circulation pump is lower than normal, it reflects that the circulating pump efficiency is flow down. Maybe a heating pipe fouling blocking shall be clean. (2)If the circulation pump pressure is stable, but the current rises and the flow falls , it illustrates that the fluid has gone bad, and the viscosity increases. we shall promptly replace or regenerate it. If it is a result of water or decomposition of gas in the new heat conduction liquid in the system has not been ruled out, then we should immediately open the vent valve to discharge gas. 3, the common problems in the chain grate operation the grate stop running, it maybe the chain is too loose, and sprocket meshing is bad, or a chain wheel has wore seriously, in connection with the chain badly; solution : adjust screws on both sides, and taut the grate .If it still abnormal, we need to change the chain grate stuck . Grate stucks. it may because link break loose or pin link falls off ; It can be also because the metal inclusions in coal grate gets stuck in or because of link hog; or caused by Slag (eagle) iron tip sinking, then gets grate stuck in. Processing method: inverted a grate to remove debris, then replace the broken link, then restarted ,.if it does not effect , then stop running and begin a detailed check.
