Further there are other water level indicator such as water level sensors, probes sensors. You can get hot burns when exposed to hot surfaces or in contact with hot boiler water. pressure : The pump to boost the F.O pressure for injection is not generating enough pressure due to myriad reasons, therefore a stand-by fuel oil pump is started to supplement the loss in pressure, this occur because when fuel is being injected into the furnace. B12.8 Air Filter . Low pressure can cause issues, as we’ve seen with gurgling noises, but so can high pressure. 4) High high water level: If the water at level H1 is not acknowledged, the feed water pump will stop at level H2, therefore cutting water supply to the boiler drum, the feed pump stops to prevent the drum of boiler from excessive hydraulic pressure exerted by the feed water, which may explode the boiler drum(at-least weaken it). Required fields are marked *. on Boiler Alarms And Trips | 5 Common Boiler Safety Devices.
