What are the advantages of induced draught cooling tower over forced draught cooling tower?
When a project is originally designed, the designer must decide whether a natural draft or mechanical draft tower offers the best economic result.
Mechanical draft towers are substantially less costly to purchase, but have the disadvantage of having a continuous auxiliary power draw. They are also physically smaller and shorter.
Natural draft towers consume no auxiliary power, but are very expensive to purchase and erect. They are very large and tall. Often times, plants do not have enough "real estate" to fit such a large structure.
One must do an economic analysis to establish which option is the best choice, economically.
They are also simpler, not having any moving parts

Can Forced draft fan can be used as a induced draft fan?
A forced draught is where the air flow comes directly from the fan to the object. Such as an hair dryer.An induced draught is where the air flow is induced {lit lead in} by a separate flow of air. For example, an abrasive jet would quickly wear out if the abrasive passed through the jet nozzle. the flow of abrasive is added (induced) into the air flow by a jet of clean air.If an air flow is corrosive or very dirty then an induced flow system would be appropriate.
What are the applications of forced convection?
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
Is forced draft has negative pressure drop?
No, the forced draft fan has positive pressure as it just forces yhe air into the combustion chamber.only the induced draft fan has negative pressureas it removes the flue gases & exhaust gases is stacked up
What is odaf cooling in a transformer?
Oil Directed Air Forced , it's speical way to cooling transformers through predetermined pathes in transformer windings . this way provids fester rate of heat transfer .
What is forced cooling in transformers and name and explain them?
Most power transformers I have seen are filled with oil, and have a base rating of ONAN - which stands for oil natural, air natural. This is a cooling type. There are two main ways to cool a transformer above this rating - by using forced air - essentially attaching fans to help pull heat away, or using oil pumps. With air, the next typical rating is ONAF, or if there are two different ratings (meaning some fans turn on at one, and all fans turn on at two) they may be named ONAF1 ONAF2. thiws stands for oil natural, air forced. If oil pumps are installed, the rating will be OFnn for oil forced. It is possible to have both oil forced and air forced, or just oil forced - OFAN or OFAF. Just an FYI, in my experience oil pumps are typically avoided. It was discovered that pumping the oil can cause a static voltage buildup in the oil, which can lead to catastrophic failures; this doesn't seem to be a problem if oil pumps are not used.

Types of cooling tower?
There are dfferent types of cooling towers available in Industry. Some of the commonly is used cooling towers are Round Cooling Towers Square Cooling Towers Dry Cooling Tower Wooden Cooling Tower Cross Flow Cooling Tower Modular Cooling Towers Evaporative Cooling Towers Natural Cooling Towers Counter Flow Cooling Towers Get a highly durable cooling tower according to your industry.
Standard transformer cooling methods?
Standard transformer cooling methods include; Air cooling and oil cooling.AnswerTransmission and distribution transformers are oil filled. Cooling is achieved either by natural convection yo the sides of the tank (small distribution transformers) or through cooling tubes, or by pumped circulation through external heat exchangers. The heat exchangers themselves, are cooled by natural convection, forced air draught, or water.
Why induced draft fan capacity is more compare to forced draft fan in power plant?
Because it is induced
What is adiabotic cooling?
Adiabatic cooling deals with the cooling of parcels of air as they rise, or are forced up, through the atmosphere.
Supplier induced demand?
Supplier induced demand is demand that is forced by suppliers into the market. One of the ways of inducing demand is through promotional offers and incentives.
Can a forced hot air system also be used for cooling?
no
What are the applications of forced convection?
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
What type of air cooler is normally preferred forced draft or induced draftwhy?
the induced draft type is more expensive than the other type, however it is often preferred because it is more efficient.
Forced draft fan vs induced draft fan?
In a balanced draft boiler, you actually have both: forced draft (FD) fans supplying air to the furnace, and induced draft (ID) fans removing flue gas. Typically, the FD fans control airflow, while ID Fans control furnace pressure to slightly below atmospheric pressure. In general though, the choice between forced draft and induced draft is based on how "tight" the system is - if you have leaks, it is better to use ID, as FD will cause product loss.
What type of cooling is used in dry atmospheres in transformer?
forced air and draft oil dissipate
What is amplitude of forced vibrations?
The amplitude of forced vibrations refers to the maximum displacement of a system from its equilibrium position when subjected to an external driving force. It is a measure of the intensity or strength of the vibrations induced by the external force applied to the system.
