(1)Using inferior fuel
(2)The slow-burning mode of a long-term stove or fireplace
The fuel for wood stoves or fireplaces should be taken into consideration first and foremost; dry wood from hardwood trees is required to heat the stove.
The humidity of firewood shouldn't be higher than 20% in order to ensure complete burning and minimal soot and soot formation. This level of moisture content in firewood is attained throughout the drying process and storage in the open air for a year to a year and a half.
Freshly cut, raw firewood is not permitted because the moisture present prevents you from achieving the ideal furnace temperature necessary for complete fuel burning. When raw wood is burned, extra moisture and products combine to create an acidic, aggressive atmosphere that settles on the glass and compromises its structure, causing plaque, white spots, and turbidity to appear.
Additionally, issues with clouding of the glass frequently develop when utilizing inexpensive, subpar fuel briquettes. Woodworking businesses use production waste to make a lot of briquettes. Some dishonest manufacturers violate production techniques, use sawdust from coniferous trees with a high resin and moisture content, as well as different chemicals that interfere with the clean combustion of fuel and result in the formation of soot soot in significant amounts, which ultimately results in the clouding of the fireplace glass.
