DRYBACK BOILERS
Advantages of a Dry-Back Boiler:
Cost-Effectiveness: Dry-back boilers typically have a lower initial cost compared to wet back boilers due to their simpler design and reduced material requirements.
Ease of Maintenance: With no water in direct contact with the rear of the boiler, dry-back boilers are generally easier to clean and maintain. The refractory lining can be inspected and repaired without draining water from the boiler.
Versatility: Dry-back boilers are well-suited for a wide range of applications and industries, including commercial, industrial, and institutional settings.
Suitable for Low Pressure: Dry-back boilers are often used for low-pressure steam applications, such as heating systems, small industrial processes, and other applications where high-pressure operation is not required.
Stability at Low Loads: Dry-back boilers tend to be stable and reliable even at low loads, making them suitable for applications with variable steam demand.

Features of a Dry-Back Boiler:
Combustion Chamber: The rear of a dry-back boiler is lined with refractory materials to protect the boiler shell from the high temperatures generated during combustion.
Flue Passages: Combustion gases flow through the flue passages or boiler tubes at the front of the boiler before reaching the combustion chamber at the rear.
Simplicity: Dry-back boilers are relatively simple in design, making them easier to maintain and repair compared to more complex boiler designs.
Space Saving: The dry-back design can be more compact, allowing for installations in areas with limited space.
