Flue Gas Air Preheater

Flue Gas Air Preheater

What is a Flue Gas Air Preheater?

A heat exchanger called a flue gas air preheater is used to extract heat from the flue gases that are created during combustion. It transfers that heat to the incoming air supply, thereby raising the temperature of the air before it enters the burning part. This process helps reduce the amount of fuel needed to reach the high temperature and save a lot of energy.

Key Benefits of Flue Gas Air Preheaters

Improved Energy Efficiency
By using the heat from exhaust gases to preheat incoming heat air, the need for additional fuel is reduced. This results in lower energy costs and improved overall efficiency of your system.
Cost Savings
The recovery of heat lowers parts costs by decreasing fuel consumption. With increasing energy prices, these savings become even more significant over time.
Environmental Benefits
Efficient heat recovery reduces emissions by lowering fuel usage, which is beneficial for both the environment and regulatory compliance. This can help your organization meet stricter environmental standards.
Extended Equipment Life
By maintaining optimal temperatures and reducing the thermal load on your combustion system, Flue Gas Air Preheaters can prolong the lifespan of other critical components of your system.
Flexibility
Flue Gas Air Preheaters come in various designs and configurations, making them adaptable to different industries, including power plants, cement kilns, refineries, and more.

How Do Flue Gas Air Preheaters Work?

Hot flue gases leave the combustion chamber and move into the preheater for heat recovery.

Heat Exchange

• Regenerative Preheaters: Rotating matrices allow regenerative preheaters to accept waste heat from the flue gases and transfer heat to the incoming make-up air.
• Plate Preheaters: Use plates or tubes where the cold air and hot flue gases travel separately, with heat exchanged across the surfaces.

The incoming air is heated before entering the combustion chamber, which reduces fuel consumption.

Case Study: Flue Gas Air Preheater in Power Generation

Background
A coal-fired power plant in the U.S. was struggling with high fuel costs and increased emissions. They needed a way to improve energy efficiency while complying with stricter environmental regulations.
Challenge

• The plant's high fuel consumption resulted in elevated expenses.
• The plant had to lower its emissions to meet new environmental standards.
• Equipment was wearing out due to excessive heat load, shortening its lifespan.

Solution
The plant installed a regenerative flue gas air preheater to capture heat from the flue gases and use it to preheat incoming combustion air. This helped reduce the amount of fuel needed to reach the required temperature.
Results

• Fuel Savings: Reduced fuel consumption by 25%.
• Cost Savings: Operating costs dropped by 15%.
• Lower Emissions: Carbon emissions decreased by 18%.
• Extended Equipment Life: Equipment lifespan increased by 10-15 years.

Frequently Asked Questions (FAQs)

1. What is a flue gas air preheater?
It's a system that captures heat from exhaust gases and uses it to warm up the incoming air, reducing the need for extra fuel during combustion.
2. How does it work?
It uses a heat exchanger to transfer heat from the hot exhaust gases to the cold incoming air, helping save fuel and improve efficiency.
3. How much maintenance do they need?
They require very little maintenance. Regular cleaning and checks ensure they continue running efficiently.
4. Can I retrofit a flue gas air preheater into my existing system?
Yes, our preheaters can be fitted into most existing systems.
5. How long does installation take?
Usually, it takes about 4 to 6 weeks to design and install the system.
5. Can I get a custom solution?
Absolutely! We'll design a system that fits your exact needs.
