What You Need to Know About Waste Heat Recovery
Introduction
Plant engineers and managers understand that energy is a costly line item for their facility operations. More so, the expenses associated with natural electricity and gas continuously grow yearly. Therefore, ensuring your system runs efficiently is vital to maintaining cost-effectiveness. That is where waste heat recovery boilers come in handy.
This post will shed light on recovering waste heat, how a waste heat boiler works, and the benefits plant managers can enjoy from using this equipment. Read on to learn more.
What is Waste Heat?
Waste heat refers to the heat produced when a tool or machine operates. It exists in each technology and application, from car engines to computers, televisions, vacuum cleaners, jackhammers, fans, lighting, CNC machines, and more.
A significant amount of this heat is dissipated and lost into the environment – hence its name “waste.” Around 20% to 50% of the country’s energy input is dissipated as lost heat, according to the Industrial Technologies Program by the US Department of Energy.
Recently, many organizations and governments have committed extensive resources to research more about waste heat recovery. They have also designed numerous strategies for harvesting the lost heat and utilizing it to enhance energy efficiency. One of the most popular recovery techniques is waste heat recovery.
How a Waste Heat Boiler Works
Heat is lost at various points across the boiler system, including heat loss from boiler exhaust, pipes, and warm air produced from heating rooms. These recovery boilers utilize this heat to produce more steam for industrial use.
They use the same principle as regular boilers but use energy that exhaust gases produce instead of a burner. Hot exhaust gases enter a big chamber from a process chamber and move inside pipes with cold water. The heat from the pipes warms the water until it attains its boiling point, forming steam—the steam and cooled waste gas exit the recovery boiler in separate pipes.
The steam can go through pipes across your facility or be used to move turbines to produce electricity. An auxiliary burner can increase the steam output of the heated gases that don’t have sufficient energy to evaporate the water.
Advantages of Recovering Waste Heat
Heat recovery provides your facility with numerous advantages. Here are some of them:
- It offers more steam output
- It increases fuel efficiency
- It reduces emissions to the environment
- It decreases operating expenses
Conclusion
Waste heat boilers are available in a broad range of capacities and sizes to suit your facility’s needs. Gas intakes typically handle around 1000 to 1 million ft3 per minute, increasing steam output for industries such as ferrous and non-ferrous metals, refineries, chemicals, glass, and other industries that need extra steam.
A waste heat boiler can only produce steam if the process is running. Therefore, they supplement the existing boiler systems but don’t replace them. Although they can cost much to install, they will cost you less operation and maintenance costs, providing a quick return on investment.
