What are the commonly used liquid fuels for heating boilers?
07 Jan 2022
Liquid fuels mainly include petroleum, gas oil, kerosene, heavy oil, coal tar, gasoline, alcohol and so on. The liquid fuel is mainly composed of seven components: carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), ash (A) and moisture (M). It is characterized by high content of carbon and hydrogen and low moisture, so its calorific value is very high, usually 40600〜43100kJ/kg.
What are the commonly used liquid fuels? There are three main types: heavy oil, residual oil and light diesel oil. Diesel oil is generally used for ignition and stable combustion of small and medium-sized heating boilers, domestic boilers and large boilers, while heavy oil is mostly used for utility boilers.
