Induced And Forced Draft Fans – Crucial For Many Manufacturing Plant Processes

Induced draft (ID) and forced draft (FD) fans are crucial elements in many processes specific to manufacturing plants. These blowers are particularly valuable in sectors such as cement manufacturing, power generation, and chemical processing.

• When forced draft fans are considered, it becomes evident that they supply the fresh air necessary for the efficient completion of the combustion process. Here, even the induced draft variants play a significant part by quickly eliminating flue gases that accumulate in the system. This ensures that the air-to-fuel ratio is appropriate and that there is no excessive pressure in the system.
• This can be treated as a continuation of the previous point. As the ID blowers gather the flue gases and expel them into the atmosphere, the pollution levels are minimized. The manufacturing plant can conform to the corresponding environmental laws.
• Both these fans make sure that the pressure inside kilns, furnaces, and boilers always remains balanced. This avoids fluctuations that could negatively affect the process efficiency. Also, the negative pressure generated by induced draft fans prevents gas escape.
• Induced and forced draft blowers operate so that there is a marked decline in the energy utilized within the combustion systems. This leads to a noteworthy decrease in the costs related to energy. Over time, the business will be able to witness that the overall operational costs of the plant have come down. The fact that this contributes to the revenues warrants no special mention.
• We now come to an aspect that is worthy of special mention. Many of the FD and ID fans presently available in the markets have been designed by integrating the latest technologies in them. Here, we can take the example of VFDs (variable frequency drives). Blowers fitted with VFDs have a unique feature. Their speed can be regulated as per the precise requirement of the system at a given moment. This again enhances the efficiency of processes.
• Forced draft fans make certain that there is no interruption in the supply of outside air into the combustion chamber. As a result, the process of combustion is never left incomplete; it progresses in a hassle-free way. And when combustion goes on properly there is no accumulation of hazardous gases within the chamber. Such a buildup seriously compromises workplace safety.
• The mode of operation of induced draft fans stops both excess heating of the system and the reverse flow of gases. This significantly brings a drop in the possibility of an explosion and the risk of any damage to equipment is reduced, too.
• When examining plants and factories in the steel and cement sectors, the presence of ID and FD blowers becomes much more essential. These fans assist in safely transporting raw materials from one point to another. Additionally, the blowers ensure that the premises are kept protected from fumes and dust to the maximum possible extent. There is an increase in the overall productivity.
• In plants where cooling and drying are salient processes, these fans contribute significantly.

The fans make the processes progress as required; the end product is of superior quality.

Without the deployment of industrial fans, plants, and factories will be hit by a decrease in the quality and quantity of production. They will face non-compliance issues with environmental regulations, as well.
