The draft or draught of a ship’s hull is the vertical distance between the waterline and the bottom of the hull (keel), with the thickness of the hull included; in the case of not being included the draft outline would be obtained. Draft determines the minimum depth of water a ship or boat can safely navigate.

Draught And Classification of Draught – BrainKart

The draught required in actual power plant is sufficiently high (300 mm of water) and to meet high draught requirements, some other system must be used, known as artificial draught. The artificial draught is produced by a fan and it is known as fan (mechanical) draught.

Flue Draught and Flue Liners – The Stove Yard

Providing the correct amount of flue draught or ‘pull’ is critical to the successful performance of your stove. It helps draw vital air into the stove combustion chamber, removes the harmful products of that combustion through the flue and then disperses them to the outside air and into the atmosphere.

Draft Measurement Guide for Chimneys & Flues

Normally we measure draft at two locations: over the fire or in the combustion chamber where typically we may see -0.02 to -0.03 inches of water column pressure, and in the breech or at the stack pipe (properly, the flue vent connector) measured just a few inches above the boiler or furnace top, and before the barometric damper itself.

What is Boiler Draught? Types, Classification, …

Boiler draught is defined as the difference between absolute gas pressure at any point in a flow passage and the ambient (same elevation) atmospheric pressure.Draught is achieved a small pressure difference which causes the flow of air or gas to take place. It is measured in millimetre (mm) or water.

Lecture 9 – Boiler Draft (Draught) system (ST. Gen. …

Flue gas stack (chimney) A chimney is a structure for venting hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney, effect. The space inside a chimney is called a flue.

Section 3 – Module 7: Boiler Draft and Flue Gas …

The induced draft fan which is required to provide the same volume of air, is larger than a forced draft fan, due to the following: 1. The ID Fan must move a larger mass because flue gasses consist of the mass of fuel as well as the mass of air 2. the ID fan must be able to ahndle any air leakage in the boiler setting 3.
