Detailed explanation of sludge modified carbonizationresource utilization technology

A modifier is used to convert the organic matter such as protein and sugar in the sludge into oil and gas. The oil and gas becomes oil and gas in the carbonization process. The oil and gas is exported from the carbonization furnace and burned in the combustion chamber, which provides a main energy source for the carbonization furnace.
