Thermostat
There is probably a thermostatic control somewhere that shuts it down when some temperature limit is reached, and on again when the temperature gets too low. Alternatively there might be a fault which shows up when the furnace gets too hot.
A furnace by definition provides heat. There must be something that controls that heat; that is that tells the furnace when to fire up the burners and when to shut down the burners. This function is provided by the furnace control system. Usually the control system itself is controlled by a thermostat which maintains the temperature at a preset level on the thermostat.
A blast furnace runs continuously, and input materials are continually dumped in at the top to make their way down through the furnace. Shutting down a blast furnace for relining or other work is a major event in its life.

With winter upon us, the important thing in keeping your home comfortable is making sure that your furnace is in good shape. Without a decent furnace, one that works well and can hold up to any kind of endurance test you put it through in the dead of winter, you can expect to be sharing the bed with the kids every night as they try to stay warm. If you want to make sure your furnace works and keep furnace repair costs down, call your furnace services in for a tune up at the start of winter to prevent breakdowns.
Every hot water heater I've seen has a regulating knob somewhere. Look for it,possibly under a cover.
To shut down a coal furnace, follow these steps: 1) Turn off the power supply to the furnace. 2) Close the air intake and exhaust dampers to restrict airflow. 3) Allow the fire to burn down and the furnace to cool before removing any remaining coal or ash. 4) Dispose of the coal ash properly and clean the furnace as needed.
Iron is removed from a blast furnace through a process called tapping, where a hole at the base of the furnace is opened to release the molten iron. The iron is then cast into molds to solidify and form pig iron or further processed into steel.
Remove any stones, put the jewelry into a crucible, and the crucible into a furnace, heat until melted, pour into molds. A blowtorch would do the job as well, ideally oxy-acetylene.
Shut Down Temperature
If you are using water and not steam there should be a temperature controller mounted in the side of the boiler, that is where the start and stop point of the boiler is controlled.
