What types of kitchen fuel oil and their characteristics?

Types and Characteristics of Kitchen Fuel Oils

Plant Oil Fuel

Biofuel Defined & Ingredients: Biofuels produced through esterification, primarily composed of refined vegetable oils or bio-blended oils; some vendors may use non-plant-based materials such as white oil, liquid paraffin, etc.

Advantage:

High Calorific Value: Up to 11,000 kcal/kg, superior to liquefied gas (8,000-8,500 kcal/kg).

Environmental Friendliness: Low pollution after combustion, biodegradable, and compliant with green kitchen standards.

Safety: Flash point ≥ 80°C, not classified as hazardous chemicals, with low storage and transportation risks.

Lightweight White Oil

Feature: Colorless and transparent liquid, with a high flash point (≥80℃), non-flammable by open flame, odorless and non-toxic.

Application Scenario: Commercial kitchen electric spray burners, carbon-free and odorless combustion, heat value approximately 11,000 kcal/kg.

III. Liquid Wax

Features: Similar to lightweight white oil in performance, high cost-performance ratio, calorific value of about 11,000 kcal/kg, and stable combustion.

Four: Blended Oil

Composed of: Based on white oil or liquid paraffin, blended with hydrophobic solvents, appearing in a light yellow color.

Performance: Equivalent to paraffin wax in calorific value (11,000 kcal/kg), with a non-irritating combustion odor.

Ethylene Glycol Fuel (Not Recommended)

Flaw:

Low Caloric Value: Caloric content ranges from 3,900 to 4,680 kcal/kg, with high unit energy consumption.

Economic Disadvantage: While the unit price is low, the consumption far exceeds that of vegetable oil fuel, resulting in higher overall costs.

VI. Other Fuels

Fuel: Alcoholic-based, flash point <60°C, classified as a hazardous chemical, posing incomplete combustion and pollution issues.

Diesel/kerosene: Traditional fuels that produce black smoke and harmful gases, increasingly being replaced.

Comprehensive Recommendations

Priority Selection:

Vegetable oil fuels (especially bio-mixed types) or light paraffin oil, balancing high calorific value, safety, and environmental friendliness.

Refined oil serves as an economical alternative, ideal for commercial settings with limited budgets.

Avoid using:

Ethylene Glycol and other alcohol-based fuels, due to their low energy efficiency and significant safety hazards.

Traditional diesel, kerosene, and other polluting fuels.

The current mainstream kitchen fuel oils are primarily plant-based and mineral-based (such as white oil), and it is necessary to choose clean energy with high calorific value and low risk based on actual needs.
