The purpose of a steam radiator valve is to control the amount of steam that enters the radiator, thus regulating the heat output of the radiator. The valve opens and closes to allow more or less steam to flow through the radiator, adjusting the temperature in the room.
The purpose of the air valve in a steam radiator system is to release trapped air from the system, allowing steam to flow freely and efficiently heat the radiator.
Steam radiator valves should always be fully open, or fully closed. Steam enters the radiator from the boiler, and fills the radiator. The air vent shuts, having sensed moisture inside the radiator. The steam then cools, condenses to water, and drains from the radiator. If you leave a valve partially open, then the steam enters easily, because of the pressure. But, the water has a difficult time draining, so the radiator can collect it, and steals it from the furnace, which needs it for resupply.

There are plenty of ways a car can break down without the radiator being a part of the cause. As for the reason you'd see steam from a radiator, it would escape if there was a leak in the radiator or the hoses, or if the cap was opened. The contents in a radiator are very hot - hot enough to produce steam.
Thermal energy from the steam is transferred to the radiator through conduction. The steam flows through pipes within the radiator, heating the metal walls. Heat is then transferred from the hot metal to the surrounding air in the room.
The thermal energy from the steam is transferred to the radiator through convection. As the steam flows through the pipes of the radiator, it releases heat energy to the surrounding air. This heating of the air increases its temperature, which then warms up the room.
When your radiator fails in a car, your car will overheat. Sometimes it will explode with steam. Usually you lose your radiator coolant. Often you will have to replace your radiator.
It is very doubtful that it is smoke. It is most likely steam. Either there is a pinhole leak in the radiator allowing hot coolant to escape that then vaporizes into steam when it hits the atmosphere... or there is something spilled on the radiator that steams when the radiator gets hot. Have the radiator pressure tested for leaks.
A wall steam radiator works by using steam from a boiler to heat metal fins inside the radiator. The heat from the fins warms the air around the radiator, which then rises and circulates throughout the room. This process efficiently heats the room by using convection to distribute the warm air evenly.
As steam gives up energy inside the radiator, it undergoes condensation and transforms back into liquid water. This process releases heat energy that warms up the radiator.
A radiator is defective if fluids are leaking out of the radiator or there is a leak of steam. Or, if thecore is blocked, the radiator will remain cold or just slightly warm in places.
