INDUCED DRAFT FAN PERFORMANCE

induced draft fans from Reitz india.
Induced draft (ID) fans are among the most pivotal elements in many plants and 
manufacturing units. The primary function of an ID blower is to gather the gases and 
contaminants in the combustion chamber and expel them into the outside 
environment. To achieve this goal, these fans generate negative pressure. However, 
ID fans can provide the expected benefits only when measures are initiated to 
ensure that the performance of these blowers is consistently optimal.
Developing the right strategies and integrating the related technologies are 
examples of those initiatives. This particular write-up will elaborate on the salient 
aspects of optimizing induced draft fan performance
 The rate of airflow of the fans is a key parameter for selecting the correct 
model. There is no fixed standard for how much airflow rate is required; this 
varies from one plant to another. The business has to be clear about its precise 
requirements. It is only then that the ID fans with the right airflow can be 
deployed.
 It has to be made sure that the pressure that the induced draft blowers support 
conforms to the requirements of the facility. If the processes are complex, it is 
better to opt for blowers of high pressure.
 There are several designs of these blowers available in the market, such as 
backward inclined fans and variants that are backward curved. We also have 
designs like high-pressure radial shrouded and high-pressure radial open fans. 
Here again, the exact operations of the plant/facility determine which is the 
most suitable design for the premises.
 
 The induced draft fans are sold in a variety of sizes. And, the facility/plant needs 
to exercise the utmost caution to choose the version of the proper size. It 
should perfectly match the process specifications.
 
 As it is, the ID fans are made to operate in a harsh environment where they are 
more vulnerable to issues like erosion and corrosion. Therefore, it is preferable 
to bring in blowers that are made from materials like stainless steel or carbon 
steel. If the processes in a plant are highly rigid, it’s desirable to deploy blowers 
designed to handle things like excessive vibrations and temperature 
fluctuations.
 
 The company must strive to improve the control system of the ID fan, to bring 
about a proportionate rise in its performance levels. This enhanced 
performance automatically boosts the overall efficiency of the processes. Here, 
depending on VFDs (variable frequency drives) is recommended.
 The management is necessitated to design appropriate strategies to keep the ID 
fans operating at their best consistently. The facet of preventive maintenance 
has to invariably be inclusive in those strategies. Carrying out maintenance 
works at regular intervals significantly lowers the possibility of sudden, costly 
repairs. That is always more viable than waiting for any major issue to manifest.
 
 Making certain that the configuration and sizes of outlets and inlets are proper 
is paramount, too.
 
 In contemporary times, plants and other facilities will be furthering their 
interests by incorporating the latest relevant technologies into the processes. 
With this, monitoring and operating the fans from even remote locations 
becomes a simplified matter.
 
 Also, modern technologies enable factories and plants to predict the snags that 
blowers are likely to develop well in advance. It’s not just that, prompt alerts are 
sent to the personnel, as well. Timely action can then be taken to quickly rectify 
the issue in an uncomplicated way.
