Process Industries these days are growing extensively and rapidly. While it is indeed advantageous for the growth and progress of an economy, it is undeniable that industries are one of the major contributors to the ever-increasing pollution and environmental harm. With the increasing industrial operations, there has been a resultant increase in the pollutants and greenhouse emissions from the industries that are harmful to the climate and people. Therefore, to reduce the negative consequences caused by industrial waste, process plants opt for Waste Heat Recovery Boilers for manufacturing operations.
As the name suggests, Waste Heat Recovery Boilers are systems that recover or extract excess heat and convert it to useful thermal energy for utilizing it in other operations. The type and extent of wastes released depend on the industry. Therefore, Waste Heat Recovery Boilers must be resilient enough to absorb heat from different types of emissions. Rakhoh Boilers manufactures Waste Heat Recovery Boilers that are customized as both fire tube and water tube construction depending on the industrial requirements.
Structure of Waste Heat Recovery Boilers:
Waste Heat Recovery Boilers are in most cases, designed as per the factors concerning the waste emission from the industries. However, the amount of steam generation or heat transfer depends on the amount of heat available in the flue gas. Industries must determine the capacity and steam pressure required for the processing operations. Some of the primary factors to consider while deciding the type Waste Heat Recovery Boiler are:
1. Fuels Used and Its Properties
2. Flue Gas Temperature in ℃
3. Flue gases generating exhaust in kg/hr. or Nm3/hr.
4. The operation or stage where the system is utilized
Benefits of Installing Waste Heat Recovery Boilers:
Waste Heat Recovery Boilers are preferred by many industries and for good reasons. It helps in both extracting and recycling the excess heat that can be used for other purposes and reducing the amount of harmful emissions in the environment. Some of the noteworthy advantages of Waste Heat Recovery Boilers are:
Higher Efficiency:
Installing a Waste Heat Recovery System in Industries leads to a profound outcome of accelerated efficiency. It is natural to conclude that extracting the excess heat, reduces the amount of fuel and the operational cycle that generally takes place for processing.
Optimal Utilization of Resources:
Natural resources are decreasing at an alarming rate with their large-scale applications in the industries. Therefore, it has become necessary for industries to control and manage the use of natural resources carefully. The excess heat is used for other heating purposes, which in turn, require a lesser amount of fuel.
Reduction in Waste:
Production of Waste is inevitable in the process industries. While a certain amount of waste is unavoidable, a major amount of waste heat is recycled with Waste Heat Recovery Boilers, which are later used for other operations. It leads to reducing the amount of waste released into the atmosphere by the process plant.
Reduction in Operating Costs:
With the consistent development in technologies, plant managers are always looking for better and effective methods to increase productivity and decrease the waste produced in a plant. Waste Heat Recovery Boilers are the ideal solution for sustainability and efficiency.
Reduction in Energy Consumption:
As mentioned earlier, Waste Heat Recovery Systems helps significantly in reducing harmful emissions and increasing efficiency. Hence, it is easy to conclude that it considerably reduces the energy consumption in the manufacturing facilities that lead to growth in annual turnover.
Manages the Harmful Emission in Environment:
Waste Heat Recovery Systems not only helps in decreasing the amount of waste released in the environment, but it also aids in recycling and reusing the harmful and dangerous emission that needs to be treated before releasing it in the environment. That is still not enough to prevent causing harm to the climate and people living nearby. Rather than disposing of these gases, Waste Heat Recovery Boilers redirect them for other industrial applications that reduce the amount of dangerous pollutants in the climate.
Industries Using Waste Heat Recovery Boilers:
Waste Heat Recovery Boilers are used by several industries such as:
1. Steel
2. Non-ferrous metals
3. Chemicals
4. Cement
5. Petrochemical
6. Distilleries
7. Power Generation
8. Rubber
9. Pharmaceutical
10. Textile
11. Paper and Packaging
