“A diamond is a chunk of coal that is made good under pressure”, so is the pyrolysis oil from the rubber scrap.
Pyrolysis oil is the end product of waste tyre and plastic pyrolysis. Pyrolysis oil is widely used as industrial fuel to substitute furnace oil and Light Diesel Oil (LDO). Typical industrial applications of pyrolysis oil as a fuel in:
- Boilers
- Furnaces
- Hot Water Generators
- Hot Air Generators
- Thermic Fluid Heater
- Power Plants
Following are some of the major advantages of Pyrolysis Oil over Furnace Oil.
- Pyrolysis Fuel Oil have low density and low viscosity hence it is not required to be preheated like furnace oil before use, therefore saves energy costs
- Calorific Value for Pyrolysis fuel oil is in range of 10400 Cal/gm +/- 3% which is higher than Furnace Oil
- Sulphur content is upto 0.9% where as in Furnace oil it is around 4% hence lower SOX pollution
- Ash Content, Water Content are considerably less as compared to furnace oil
- Pyrolysis Fuel Oil doesn’t require any type of blending with furnace oil and can be used directly for burning application even with diesel burners
- 5-10% Saving against Furnace Oil
In terms of specification Pyrolysis Oil is almost equivalent to Light Diesel Oil.
- Upto 25 -30% Saving against LDO
