Light Diesel Oil (LDO)
Introduction

What is Light Diesel Oil?
Light Diesel Oil, commonly known as LDO, is a blend of distillates and residual fuel oils. It is specifically designed for slow and medium-speed engines, boilers, and furnaces. LDO is known for its high calorific value and efficient combustion, making it a popular choice in various industrial applications.
Key Properties of Light Diesel Oil
✔ High Energy Content – Provides efficient fuel combustion.
✔ Low Sulfur Content – Reduces emissions and environmental impact.
✔ Cost-Effective – More affordable than high-speed diesel.
✔ Versatile Applications – Used in boilers, furnaces, and generators.
✔ Good Lubrication – Enhances engine performance and longevity.
Applications of Light Diesel Oil
LDO is widely used across industries due to its energy efficiency and cost-effectiveness. Some key applications include:
1. Boilers and Furnaces
- LDO is commonly used in industries like steel, textile, and cement for heating and melting processes.
2. Power Generation
- It serves as an alternative fuel for diesel generators, providing consistent energy supply.
