Why The Fire Happened Inside Dryer For Charcoal Briquettes During The Drying Process?
Oct 26, 2016

Why the fire happened inside dryer for charcoal briquettes during the drying process?


Drying process is the key process for the charcoal briquettes plant, which greatly limit the briquettes production capacity.  But the dangerous will be happened if you did not operate your dryer by right way! 


Fire were happened in drying process, is not only one technical man met in charcoal briquette plant, which is the technical development problem.

Fires,which will be heavy lost for plant, because that is not only little briquettes fire, that is the whole dryer briquettes, very dangerous accident.


Do you know the reason to cause the fire?


The vertical dryer were widely used before belt dryer. So much hot air are block inside the dryer and can not escape, which make the briquettes temperature so much,fire happened is always!


For mesh belt dryer, the reason for fire by two reason:


-- fired dust from furnace. Usually, the biomass materials or coal will be used for fuel for dryer. Following the air flow pumped by draugh fan, the fired dust will be pumped into the dryer and contact with briquettes, fire will be happened inside;


How to do to deal with this problem?

-- from the fuel of furnace, heavy oil, steam, gas can be fuel also, without fly ash, depends on your local cost;

-- try to build some “fire wall” inside and out side the furnace to block the flash ash if the coal only used for fuel;

-- change some hot pipe inside the dryer to block these problem happened;


-- hot air touched with briquettes for long time in one place: the temperature from furnace is around 250-350degree, and the touched with briquettes around 100-200 degree, and temperature inside dryer is around 200 degree. If the hot air touch with one place with one briquettes for long time, these briquettes temperature will be much and easy fired;

In order to avoid this problem, we need do some special designing for dryer, do you see the different for our dryer? pls contact with me to get more technical support, simba lee zzdybriquette@gmail.com
