Difference between Forced Drafts vs. Induced Draft Cooling Tower

2017-10-30T05:05:00.001-07:00

Over the years cooling towers have become very popular in almost all forms of industry. In the early forms of development, they were big and used a lot of space and resources to function. However, with modern technology, all that has changed.

These cooling towers are created specifically to meet the needs of different types of owners. They can be cost-effective and bulky, or carry a lot of loads but be prone to corrosion. It is therefore important to know about what are the different types of cooling towers that will suit your establishment.

In this article we will be talking about two types of cooling towers and compare them to pinpoint the difference between the two of them, induced draft cooling systems are known for its mechanical draft cooling tower. This method is considered by some as the more efficient way as it uses only half of what the forced draft cooling tower uses. The forced draft cooling tower is also known as a natural draft cooling tower.

This arrangement is draft through, where there is a fan that is placed on top of the air fills. Because of this, the air is drawn in, all with the help of the air intake mesh. The induced draft cooling system is presented in the market in a square or a round shape. It is also considered quieter than most other cooling towers.

Here are some of the points in which the two types of cooling towers can be compared for best possible selection for your industry:

Forced draft emphasizes on the chimney effect and air flow is natural whereas in the induced draft the drought of air is created mechanically by a fan.
The forced draft does not require using power except when pumping out the water. On the other hand, induced draft requires power to operate.
There is practically no maintenance when it comes to rotary equipment in case of forced draft cooling towers. Induced draft cooling towers have to have constant maintenance when it comes to rotary equipment.
Forced draft towers usually work with very low water loading for film fill and splash fills. It is applicable to tropical situations. Induced draft towers can readily operate at very high water loading speeds.
In cases of operating fill velocities, the induced draft systems have much higher operating skills than the forced draft systems.
Forced draft cooling towers can operate when the load that is available is right at the designed heat load. However, the induced draft cooling towers can operate at any given load conditions, making it better for load conditions.
The tower requires a greater area because the water loading is quite low, where the forced draft is considered. Compared to this the tower of induced draft requires smaller area.

It is also important to remember that environments also play a big role when it comes to picking the better cooling towers. Forced drafts do not do well in drier climates whereas the induced draft is perfectly fine in all weather conditions. There are wide range of Cooling Towers including Pultruded FRP Cooling Towers, FRP Cooling towers exporters, Induced Draft Cooling Tower, etc. So consider all factors before purchasing.

How Wet Bulb Temperature Affects The Evaporative Cooling Tower’s Performance?

2016-02-14T23:07:00.001-08:00

In general, engineers intend the cooling tower with evaporative system to cool process water. It’s a primary way to cool down the process water in cooling tower. Other than this, air cooling design is also there which has been introduced due to the rising temperature of the cooling tower. The selection and performance of the cooling tower relies on water flow rate, water outlet temperature, water inlet temperature, and ambient wet bulb temperature. In this post, we will learn about wet bulb temperature and its effect on evaporative cooling towers’ performance.

Ambient wet bulb temperature is a condition determined with the help of a device named as psychrometer. This device places a thin film of water on the thermometer bulb that is twirled in the air. After about a minute, it will show a reduced temperature. Wet bulb temperature is the low point when no additional twirling lowers the temperature. The below instance image will make you understand better-

While making the selection of a cooling tower cell, the design or highest wet bulb temperature of geographical area will encounter must be considered. Highest temperatures in wet bulb occur during the summer, when humidity and air temperatures are at peak.

How Poor Water Maintenance Adversely Impact On Evaporative Cooling Towers?

How Evaporative Cooling Towers Works?

Most cooling towers available in the stores are capacity rated at a “standard” temperature of wet bulb- 78°F. This means when the wet bulb temperature is 78°F, cooling tower will yield its stated capacity.

Why cooling towers lose their efficiency?

There are mainly three reasons that affect the efficiency of the cooling tower-

Scaling
Loss of air flow
Improper water flow

How to enhance the performance?

By adding tower cell capacity
By replacing the heat exchange surfaces with new clean fill
By checking the efficiency losses
By checking the proper air flow
By adjusting the water flow

Use Hybrid Or Mixed Flow Closed Circuit Cooling Towers And Save Water

2015-12-10T22:01:00.002-08:00

Hybrid cooling towers are mixed flow closed circuit cooling towers that provide efficient cold water temperatures with enhanced water conversation and reduced visible plume. These cooling towers are intended to reduce water consumption in thermal power generation, while also being modular for speedier construction. All the thermal power plants used by industries produce heat, which is a by-product. To dissipate this heat, industries use cooling tower in order to enable plants to operate in efficient way.

Hybrid Cooling Tower Operation:

In Summer

The operation of hybrid cooling towers relies on the operation of open and closed cooling towers. The top of the cooling tower has an air/water battery that allows to skip the evaporation (partially) and to use the battery (partially) only. It all depends on the weather and cooling capacity to be evacuated. With this process, considerable water can be saved and visible vapor plume can be also reduced in major quantity.

In Hybrid closed circuit cooling tower, the liquid that needs to be cooled passes through the air/water battery. With this, exhaust air will get warmed up and this will reduce relative humidity. The liquid flows through the process side of the plate heat exchanger to complete the cooling process.

Spring/Fall

The by-pass valve of the tower allows to regulate water amount to be conducted directly to the basin and the water quantity to initially pass over the packing of the tower.

Winter

The liquid of the tower is cooled by battery only and is not led to the basin. In winter, cooling is done without evaporation and thus, water consumption remains zero.

Key Components Of Cooling Towers To Enhance Water Efficiency

The hybrid mode of cooling tower uses limited water to acquire optimum performance. In this mode, cooling tower uses little amount of water to pre-cool the ambient air streaming inside the tower, lowering air temperature toward the ‘wet bulb temperature’, the minimum temperature that can be reached via evaporative cooling.

Materials used for casing and structure of cooling tower:

FRP
Wood
Concrete

You don’t need to worry about maintenance and inspection as these can be done with an ease. The mixed flow closed circuit cooling towers offer maximum operational safety.

Why Closed Circuit Cooling Tower Is Better Than Open Circuit Cooling Tower?

2015-10-27T23:22:00.003-07:00

You must know about the term 'hybrid.' A closed circuit cooling tower is a hybrid product that is used for passing the working fluids via a tube bundle. These towers are useful and more advantageous than open circuit cooling towers.

Closed circuit design of cooling towers offers evaporative cooling for sorts of systems. These towers operate just like open cooling towers and the only difference in operating is that the heat load to be rejected is conveyed from the process fluid to the ambient air via heat exchange coil.

The coil is used to separate the process fluid from the outside air and keep it free from contaminants in a closed loop. This means you will have two different fluid circuits: external and internal. In external circuit, spray water circulates over the coil and blends with outside air.

What Differentiates Closed Circuit Cooling Tower From Open Circuit Model?

In internal circuit, the process fluid circulates in the coil. When the tower is into operation mode, heat is transferred from internal circuit via the coil to the spray water, and later to the atmosphere as a share of water evaporates.

Major Advantages Of Closed Design

These towers have capacity to withstand entering fluid temperatures up to 82.2 degree Celsius as manufacturing units have used dry coil technology.
The closed loop system of the design protects the process fluid quality, lowers system maintenance and offers operational flexibility at higher initial cost.
It also prevents airborne contaminants from entering and fouling the system
There is minimal requirement of water treatment during the process.
There is no need for make-up water during dry operation periods.
Its compact design consumes less space.
Cleaner process fluid yields cleaner internal surface
Lower water treatment costs
Lower system maintenance costs

Now you know few points why closed circuit cooling towers manufacturers considered better products than open circuit cooling tower design. You can book your model online or by visiting shops of the suppliers.
