Is there a special device used for hood duct cleaning? Where can I buy such a thing?

Flex duct is a flexible, accordion-like duct made of plastic and wire, while rigid duct is a solid, inflexible duct typically made of metal. Flex duct is easier to install in tight spaces, but can be less efficient and more prone to damage. Rigid duct is more durable and efficient, but harder to install in tight spaces. The choice between the two depends on your specific HVAC system and installation needs. Consulting with a professional HVAC technician can help determine which type of duct is more suitable for your system.
Thoracic duct is a part of Lymphatic System.
You can buy a device for furncae duct cleaning on the following site: http://www.fireplacestore.com/frplcstrhome.html. They have a fantastic selection of everything fireplace.
A damper is usually a piece of metal that is installed in a duct to allow the airflow to be restricted. This lets the user open or close the restriction to adjust the amount of air getting through. There is often a metal tab handle outside the duct to rotate the damper inside the duct. The handle is parallel to the restriction plate, so the least resistance is when the handle is parallel to the duct itself. To restrict the airflow, turn the handle so that it is up to 90 degrees off from the direction of the duct.
If you can visually see a lot of dust build-up inside your duct system, or if you have mold in your duct system, it is probably a good idea to have them cleaned. Dust and mold can lead to polluted air and increased allergies in some people.
To calculate the duct diameter, you need to consider the airflow requirements, velocity of air in the duct, and the friction losses. Use the Duct Sizing Chart or an online calculator to determine the appropriate duct diameter for your system based on these factors. It's important to ensure that the chosen diameter can handle the required airflow without causing excessive pressure drop.
Ductwork is simply a duct system. Ducts are essential to the circulation of air, and ductwork describes a range of duct related fields, such as duct design.
An air duct is a duct through which air is forced or extracted, which forms a part of a building's ventilation system.

If both systems are forced air systems it's possible to use the existing duct work; however, with out viewing you project, I would suggest having an air duct specialist evaluate your system to determine if modifications are necessary .
