Types of air preheater in a boiler
The air preheaters are classified into two types based on their features and construction. These two types of air preheater are
Recuperative or Tubular type air preheater
Regenerative or Rotational type air preheater
Recuperative or Tubular type air preheater is further classified into two types, they are
Horizontal tubular type
Vertical tubular type
Regenerative or Rotational type air preheater is also classified into two types they are
Rotating baskets (Ljungstrom)
Rotating hood (Rothemuhle)
