Your question: What is volatile matter in charcoal?

What is volatile material?

A volatile substance can be defined as (1) a substance that evaporates readily at normal temperatures and/or (2) one that has a measurable vapor pressure. … However, some solid materials can change directly from solid to vapor without ever becoming liquid, a process called sublimation.

What does volatile matter consist of?

Volatile matter usually consists of a mixture of short- and long-chain hydrocarbons, aromatic hydrocarbons, and some sulfur and chlorine.

Why coal with high volatile matter is easily burnt?

Because of its high moisture, freshly mined lignite ignites slowly and is noncaking. The char left after moisture and volatile matter are driven off burns very easily, like charcoal. The lumps tend to break up in the fuel bed and pieces of char that fall into the ash pit continue to burn.

What happens when charcoal is heated?

Charcoal reacts with oxygen of the air at a glowing red heat to form colourless carbon monoxide gas, which then burns with a blue flame with more oxygen from the air to produce carbon dioxide gas. … Unburned carbon monoxide gas can be given off by burning charcoal.

Which coal has the highest ash content?

Coking coal– the carbon content is around 43%-86%. It is a type of bituminous coal. Hence, lignite has the least carbon content which means that it has the highest ash content.

What is free burning coal?

i. A bituminous coal having so little fusibility that enough air for rapid combustion can flow between the lumps and high enough in volatiles and fixed carbon to burn readily.
