How does a fire damper work?
In the event of fire, the fusible link melts and the shutter gets closed. This helps in blocking the fire from spreading through the duct ----- If you are asking about a damper on a stove or chimney, that is not called a fire damper, but just a damper. There is a link to a question on that below.
How does a damper work?
A damper restricts the air flow. In a fireplace, the damper is closed to prevent air from going up the chimney, with a resulting loss of heat in the house, when the fire is not going. When a fire is to be started, the damper is opened to create a draft to vent the smoke. In a wood or coal burning stove, the damper is variable and can be used to regulate the draft. The more widely open the damper is, the greater the draft, and the hotter to fire burns. This sort of damper cannot be closed all the way, because it is necessary to vent slow fires. Sometimes, a stove will have multiple dampers for different purposes. For example, a wood cook stove will have typically a damper on the flue, to regulate the heat of the fire, and a separate damper so the cook can choose to vent the gasses from the fire directly into to chimney, which would be how a fire is started, or around the oven, so the oven can heat nicely once a good draft is established. In other systems where air is moved, dampers can be used to stop the motion of the air. A fire damper is one such system, where the damper is used as a safety device to prevent a fire from spreading. There are links below.
What is the difference between damper and bread?

What is the meaning of a chimney cap damper?

What is purpose ship fire damper?

What is the difference between smoke damper and firesmoke damper?
Assuming your question relates to life safety in building construction, and not to parts of a wood burning device- Smoke dampers are intended to limit the movement of smoke within a building, or section of a building. They are not intended to inhibit FLAME spread. A fire damper will inhibit smoke movement, but is also insulated to stop fire. A simple smoke damper might be light weight sheet metal- but that is not enough to stop very high temprature. A fire damper is heavier, may be insulated, built of fire resistive material, etc.
How does a fire damper works on ships?
A fire damper on ships is a safety device designed to prevent the spread of smoke and flames through ventilation ducts during a fire. It operates automatically or can be controlled manually; when activated by heat or smoke, the damper closes off the duct, sealing off the affected area. This helps to contain the fire, protect crew and passengers, and limit damage to the vessel. Regular maintenance and testing are essential to ensure the damper functions effectively in an emergency.
Should you close the flue to the fireplace to keep the humidity out of the house?
The purpose of the fireplace damper is to keep the outside elements, outside. The damper is opened only when there is a fire in the fireplace.

yes
Can you adjust the damper while you have a fire?
yes you can,as long as is it doesnt cause the smoke to roll out,your fire will last all night
Why the fire damper beep even if there is no fire alarm its installed in air handling units ducts what is the reason for beeping and how to rectify the problem?
The beeping of a fire damper, even without a fire alarm, often indicates a malfunction or a fault in the damper's system, such as a low battery in the backup power supply, a stuck actuator, or a wiring issue. It serves as an alert to potential problems that could affect the damper’s operation during a fire event. To rectify the issue, first check the power supply and battery status, inspect for any obstructions or mechanical failures, and ensure that all wiring connections are secure. If the problem persists, consulting a qualified technician for a thorough inspection and repair is recommended.
When is a Fireplace flue open?
When the fire is burning, until the ashes are cold. The damper should be open at these times.
