Which are typical applications of waste heat boilers?

Waste heat boilers are used to recover heat from various industrial processes and convert it into usable energy, typically in the form of steam or hot water. These boilers play a crucial role in improving energy efficiency, reducing operating costs, and minimizing environmental impact in a wide range of industrial applications. Here are some typical applications of waste heat boilers:

1. Power Generation: Waste heat boilers are commonly used in power plants to capture and utilize heat from exhaust gases produced by gas turbines, diesel engines, or other combustion processes. This recovered heat is used to generate steam, which can then drive steam turbines to produce additional electricity, improving overall plant efficiency.

2. Refineries: In refineries, waste heat boilers recover heat from flue gases produced during the refining process, such as those from catalytic cracking units, fluidized bed reactors, or sulfur recovery units. This recovered heat can be used for various purposes within the refinery, including steam production, preheating feedstock, or heating process fluids.

3. Chemical Processing: Waste heat boilers are integral to chemical processing plants for recovering heat from various process streams, such as reactor effluents, distillation column overheads, or vent gases. The recovered heat can be used for steam generation, heating process streams, or driving absorption chillers for air conditioning.

4. Steel Industry: In steel manufacturing plants, waste heat boilers capture heat from blast furnace gases, coke oven gases, or sintering process exhausts. This recovered heat can be utilized for steam production, preheating combustion air, or heating water for various industrial processes.

5. Cement Industry: Waste heat boilers are utilized in cement plants to recover heat from kiln exhaust gases or clinker cooler air. The recovered heat can be used for power generation, preheating raw materials, or drying fuel in the kiln.

6. Glass Manufacturing: Waste heat boilers in glass manufacturing facilities recover heat from furnace exhaust gases or annealing lehrs. The recovered heat can be used for steam production, preheating combustion air, or heating process fluids.

Overall, waste heat boilers offer significant opportunities for energy recovery and efficiency improvement across various industries, helping to reduce energy costs, lower carbon emissions, and enhance overall sustainability.
