  • Troubleshooting a Boiler That Won't Shut Off

    Jan 29, 2010 · Check the Thermostat. Once it becomes clear that your boiler is heating the house when it isn't necessary, you should turn the thermostat down. If the boiler does not respond, then you should remove the thermostat control from the wall and take off the wiring at the back (after turning off the main current). Place the thermostat face down on a counter, and open the back.Learn More

  • Fire-tube boiler - Wikipedia

    A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank Learn More

  • BOILER SAFETY VALVE – MEO EXAMS PREPARATION

    By adding the 0.1 bar shut-off margin, the safety valve set pressure has to be 10% greater than 6.4 bar.
