At which temperature muffle furnace is heated for the determination of volatile matter?
What is the name of furnace used in estimation of volatile matter in coal?
Carbolite Volatile Matter Furnace
What is the importance of determination of volatile matter in coal?
High-volatile matter may also be associated with spontaneous combustion, especially in low-rank coals (Fierro and others, 1999). Hence, knowledge of volatile matter is important for safety, handling, and transporting coal.
What is the use of volatile matter in combustion?
Thus the volatile matter is an index of the gaseous fuels present. Typical range of volatile matter is 20 to 35%. Proportionately increases flame length, and helps in easier ignition of coal.
What is the meaning of volatile material?
Volatility describes how easily a substance will vaporize (turn into a gas or vapor). 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. The term volatile usually applies to liquids.
Is coal a ash?
Coal ash is the waste that is left after coal is combusted (burned). It includes fly ash (fine powdery particles that are carried up the smoke stack and captured by pollution control devices) as well as coarser materials that fall to the bottom of the furnace. Most coal ash comes from coal-fired electric power plants.
Is coal ash cancerous?
Along with an increased risk of cancer from toxic heavy metal exposure, coal ash can affect human development, create lung and heart problems, cause stomach ailments, and contribute to premature mortality.
Can coal ash be used for anything?

Will coal ash kill weeds?
Secondly, coal ash is extremely acidic and very toxic to a lot of living things. Yes, it will kill your weeds but you would be kinder to the things that live in the soil if you just applied a proprietary weedkiller. That at least loses its toxicity once it hits the soil.
Is coal ash good for dirt?
So far as benefits in the garden, coal ash can help break up compacted clay, improve drainage and probably add at least small amounts of nutrients (although not as much as wood ash). It’s also a convenient way to do something with coal ashes other than trash them.
Is fireplace ash good for anything?
They can be used to repel slugs and snails, or even to create lye for soap. But by far the most common and ancient use for wood ashes is for soil amendment. They contain lots of calcium, which neutralizes acidity, plus some potassium, phosphorus, and trace elements.
Should you remove ash from fireplace?
Did you know that it is not a good idea to remove the ash from the fireplace or wood stove every time you build a fire? Having a 1-inch layer of ash on the floor of the firebox during the regular heating season will make it easier to build and maintain a fire.
Why does wood burn better on a bed of ash?
Wood burns better on a layer of ash because the ash helps to insulate the warmth and also helps to reflect the heat back onto further pieces of wood. It can also take a while for firebox surrounds to heat up from cold, and so a bed of ash can help to get the fire going more quickly.
