First, we need to consider environmental protection. Reasonable use of heat sources can reduce environmental protection costs in the sludge drying process. Traditional heat sources use more coal. During the incineration process, they emit peculiar smell and smoke, which seriously pollute the environment. At the same time, in order to reduce emissions, green resources have reduced the investment in dust removal equipment.
Second, safety and reliability. During the working process of the sludge dryer, dust will be generated inside, and some dust may be flammable and explosive, so the safety of choosing heat source oil is very important.
Third, the stability of the heat source. The sludge dryer has a long working time, and it is necessary to always keep the temperature of the heat source appropriate to ensure the quality of the dried material.
Fourth, good flexibility. When coal quality changes, it is necessary to adapt coal to the sustainability of combustion.
