2. Actively Use Your Exhaust/Ventilation Fans. When you're showering or cooking over a hot stove, use your ventilation fans. While you may normally turn them off after you're done your activities, keep them on a little longer. This will be a big help in reducing indoor humidity. 3.Ash yield represents part of the original mineral matter in coal that does not combust. Ash yield is an important parameter for steam coals and for coals used in industrial furnaces. Increasing ash yield corresponds to lower heating (calorific) value. Most steam coals used for electricity require less than 20 percent ash content (air-dried ...
