Fuel Oil Heat Exchanger Overview

SHINING horizontal Shell and Tube Heat Exchanger is specifically engineered for Heavy Fuel Oil (H.F.O.) supply and preheating systems, serving the core of cement production—the rotary kiln burner. It reliably transfers heat from thermal oil to viscous heavy fuel oil, ensuring the fuel reaches the optimal temperature and viscosity for stable, efficient combustion in the kiln. With a robust design pressure of 5.5 MPa (shell side), a 30 m² heat exchange area, and compliance with GB150/GB151 standards, it is built for the continuous, demanding operation of a cement plant.

Fuel Oil Heat Exchanger Features

Dedicated for Cement Plant Fuel Systems

Engineered for the critical "Heavy Oil Fuel Supply and Preheating System," this exchanger is a key component in ensuring consistent, reliable fuel delivery to the rotary kiln burner, supporting stable kiln operation and production efficiency.

High-Pressure & Robust Construction

Built to withstand the severe operating pressures of industrial fuel systems, it features a shell-side design pressure of 5.5 MPa. Primary components are constructed from pressure-rated carbon steel, ensuring durability for 24/7 cement plant operations.

Ensures Optimal Combustion for Kiln Burner

By efficiently heating heavy oil, it critically reduces fuel viscosity, which is essential for proper atomization at the kiln burner. This promotes complete combustion, optimal flame shape, and helps manage NOx emissions.

Verified Integrity for Safe Operation

Each unit undergoes stringent hydrostatic tests (Shell: 6.9 MPa, Tubes: 1.3 MPa) to confirm leak-tightness and structural integrity, providing a documented safety margin for reliable operation within the fuel supply system.

Corrosion-Resistant Heat Transfer Tubes

The heat exchange tubes are made from S30408 (Stainless Steel 304), offering excellent resistance against corrosion from thermal oil, ensuring long-term heat transfer efficiency and tube life.

Horizontal & Space-Efficient Design

The horizontal configuration facilitates straightforward integration into fuel supply pipelines, saving vertical space and simplifying installation and maintenance access in crowded cement plant premises.

Primary Applications

• Cement Production: The primary application is preheating heavy fuel oil for the rotary kiln main burner and auxiliary burners in cement plants, which is critical for stable kiln operation and clinker production.
