What is the difference between induced and forced draft cooling tower?
Induced draft --- A mechanical draft tower with a fan at the discharge (at the top) which pulls air up through the tower. The fan induces hot moist air out the discharge. This produces low entering and high exiting air velocities, reducing the possibility of recirculation in which discharged air flows back into the air intake. This fan/fin arrangement is also known as draw-through. (see Image 3)Forced draft --- A mechanical draft tower with a blower type fan at the intake. The fan forces air into the tower, creating high entering and low exiting air velocities. The low exiting velocity is much more susceptible to recirculation. With the fan on the air intake, the fan is more susceptible to complications due to freezing conditions. Another disadvantage is that a forced draft design typically requires more motor horsepower than an equivalent induced draft design. The benefit of the forced draft design is its ability to work with high static pressure. Such setups can be installed in more-confined spaces and even in some indoor situations. This fan/fill geometry is also known as blow-through.
What is a draft in CAD?
Computer aided.
What is the correct draft for oil burner?
Oil burners are fan powered, the blower drives the exhaust gases away, not draft. Stack draft ,when measured will be a negative # when referenced to atmosphere. Oil burner gases are pushed out by the blower resulting in a positive stack pressure.
Why induced draft fan operate first instead of a forced draft fan?
The procedure for starting draft plant (fans) in a boiler is to start the ID Fan first. Remember that the purpose of the ID Fan is so that the Furnace operates at a slight vacuum. (See Related Link: FD Fan vs ID Fan.) Any casing or furnace leaks then allow air to leak in, rather than allowing air with pulverised fuel and fly ask to leak out.
What is the purpose of the draft diverter on a gas furnace?
It protects the Pilot Light from being blown out
What is scantling draft of a ship?
It is the deepest draft of a ship
Scantling vs design draft?
Scantling refers to the dimensions and structural details of the components of a vessel, such as the thickness of the hull plates and the sizes of the frames, ensuring the ship can withstand various stresses. The design draft, on the other hand, indicates the vertical distance between the waterline and the bottom of the hull (keel), which affects the vessel's buoyancy and stability. Essentially, scantling focuses on the structural integrity of the vessel, while design draft relates to its waterline and performance in water. Both are crucial for ensuring safety and efficiency in marine design.
What is the difference between scantling and designed draft of a ship?
Scantling refers to the dimensions and thickness of the structural components of a ship, such as the hull, decks, and bulkheads, which are designed to ensure the vessel's strength and stability. In contrast, designed draft is the vertical distance between the waterline and the bottom of the ship's hull when it is loaded to its intended operational depth. While scantling focuses on the physical construction of the ship, designed draft pertains to its performance and stability in water. Both are crucial for safe and efficient ship design and operation.
What is a sentence with the word scantling?
I'm going to need a better scantling that this one. See if you can find a good rafter in that stack of scantling over there.
When was David Scantling born?
David Scantling was born on August 22, 1966, in Riverside, California, USA.
What is design draft in ship?
A design draft is also known as a design draught. It is a complete drawing of the ship as it is expected to look when it is fully loaded.
What is ships draft?
A design draft is also known as a design draught. It is a complete drawing of the ship as it is expected to look when it is fully loaded.
What is ship's design draft?
A design draft is also known as a design draught. It is a complete drawing of the ship as it is expected to look when it is fully loaded.

What is loadline?
LOADLIN is a bootloader for Linux that can boot a kernel from within MS-DOS. Basically you run LOADLIN as a DOS application, with the kernel as a command parameter.

What is the design draft of a vessel?
The design draft of a vessel refers to the vertical distance between the waterline and the bottom of the hull (keel) when the vessel is loaded. It indicates how deep the ship sits in the water and is crucial for ensuring stability, buoyancy, and compliance with port and navigation regulations. The draft can vary based on the vessel's cargo load and design specifications, influencing its performance and operational limitations. Understanding the draft is essential for safe navigation and docking in various water conditions.
