A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil.The heated or vaporized fluid exits the boiler for use in various processes or heating applications, [page needed] [page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitationView More
A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors. Historically the term flue meant the chimney itself. In the United States, they are also known as vents for boilers and as breeching for water heaters and modern furnaces. They usually operate by buoyancy, also known as the …View More
A heat recovery system from exodraft can extract heat energy through a heat exchanger from exhausted flue gasses and convert it into hot water with the extracted heat energy. Therefore, up to 80% of the heat can be recovered, that would otherwise have been lost through the chimney system and can be brought back at converted to the heating system.View More
Forced Draft Fan (FD Fan) in Boilers. As we know, for a Steam Boiler to generate steam, combustion must occur, be it any fuel (wood/coal/rice husk/pet coke/LDO/Furnace oil) and for combustion to exist one of its three main requirements, is the air. And this requirement is compensated by a Forced Draft Fan.View More
2. Water tube boilers: Water tube boiler is a type of boiler in which water passes through the boiler where the tubes are placed in combustion chamber. They are Babcock & Wilcox boiler : Babcock and Wilcox, this type has a single drum, with feed water drawn from the bottom of the drum into a header that supplies inclined water-tubes.View More
Jan 15, 2019· What is boiler? It is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical …View More
Example - Natural Draft. Calculate the air flow caused by natural draft in a normal family house with two floors. The height of the hot air column from ground floor to outlet air duct above roof is approximately 8 m.The outside temperature is -10 o C and the inside temperature is 20 o C.. A duct of diameter 0.2 m goes from 1. floor to the outlet above the roof.View More
Jan 10, 2017· Induced draft fan is normally located at the outlet between dust collector and chimney. The fan takes hot flue gases from the boiler through dust collector and delivers it to the chimney into the open atmosphere. ID fan creates negative pressure or suction to discharge the gases out after combustion from the furnace.View More

May 21, 2020· FLUE: A vertical pipe or duct that provides a safe pathway for heat, smoke and other combustion byproducts away from the fireplace. Lies within the interior of the chimney. Flues must be high enough to ensure sufficient draught — around 4.5m in most cases. FLUE CONNECTOR: Connects the fireplace to the flue. Bends shouldn’t exceed 45°, toView More
Additional flue gas draught will also contribute to a longer boiler life, as it will work with the correct output. You will notice the effect of the additional flue gas extraction when you open the loading door. Then the draft of the chimney is …View More
The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow. Keeping this in view, what is a natural Draught flue?View More
Mar 05, 2021· What is a boiler forced Draught fan? Forced Draft Fan is a type of a fan supplying pressurized air to a system. This fan supplies air to the Air-Preheater, where it captures the heat from the flue gases coming from the Boiler Outlet. What is ID and FD in boiler? An ID fan removes flue gases from a boiler and forces exhaust gas up a stack.View More
height of chimney and the draught can be increased by allowing the flue gases to leave the combustion chamber at higher temperatures. This reduces the overall efficiency of the plant. 14:47:07 www.joshikandarp.webs Nearly 20% heat released by the fuel is lost to the flue gases. The chimney draught is only used for very small boilersView More
May 12, 2020· 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.View More

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.View More
Understanding Draft. In the oil heating industry, “draft” describes the vacuum, or suction, which exists inside most heating systems. The amount of vacuum is called draft intensity. Draft volume specifies the cubic feet of gas that a chimney can handle in a given time. Draft intensity is measured in “inches of water”.View More
draught systems was provided for the building’s water heaters and steam boilers. The six chimney flues connected to these heating appliances run mostly horizontally through the building, terminating to the outside via sidewalls or through the ground for aesthetics. The draught system also provides ventilationView More
Try extending your fireplace flue upwards a foot. And review the draft hazard for the water heater with a qualified chimney sweep or similar expert. On 08-28 by Mike. 3 years ago I had a high efficient (90 plus) furnace installed and this is vented horizontally to outside via a …View More
Chimney Draft Calculator: Chimney draft is required to draw the flue gases from the system and in order to prevent the backflow of gases the draft generated by chimney must be calculated accurately.Chimney draft depends on the following factors as mentioned below:-. Density of gases at the inlet of the chimney – Flue gases density at the inlet of the chimney is dependent …View More
Jan 19, 2016· Boiler Draught :- The draught is one of the most essential systems of thermal power plant which supplies required quantity of air for combustion and removes the burnt products from the system. 9.
