With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.
The problems of the high exhaust gas temperature in the biomass boiler which moves normally are analyzed, and the anti-balance method to get the boiler efficiency is used to get the relationship
Mar 15, 2017 · Detailed logs of boiler operation and maintenance can help ensure boiler safety. Boilers should always be brought on line slowly and cold water should never be injected into a hot system. Sudden changes in temperature can warp or rupture the boiler.

The problems of the high exhaust gas temperature in the biomass boiler which moves normally are analyzed, and the anti-balance method to get the boiler efficiency is used to get the relationship between the exhaust gas temperature and the boiler efficiency. Greater exhaust gas heat loss, smaller the boiler efficiency. According to 35t/h biomass grate boiler, the factors which affect exhaust gas temperature
