05/07/2009Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses

What is the moisture content of a charcoal briquette? Moisture content is mainly affected by the feed stock species and its properties. The optimal moisture content is around 10 – 18 %. When the moisture content is lower than 10% or higher than 18 %, particles of feed stock are not consistent and briquette is tended to fall into pieces.

Hygroscopic dust such as sugars, salts, and lime actively absorb moisture from a gas stream and can become very difficult to dislodge from filter media. As a general rule, dust collectors perform best when the relative humidity of an air stream containing hygroscopic dust is kept at or below 40% RH.
