Vertical Incinerators

The vertical incinerator is a type of furnace suitable for waste incineration developed based on the traditional vertical furnace. The vertical incinerator has been applied in the process of co-disposal of domestic waste in cement kiln with the characteristics of simple structure, convenient operation and moderate processing capacity. It adopts the operation mode of upper feeding, lower discharge, upper gas outlet, and lower (or waist) oxygen supply combustion, which is one of the most basic traditional calciner types. The main function of a vertical incinerator is to burn or incinerate. The organic ash after the combustion or incineration of domestic waste directly enters the cement kiln system with the incineration gas, and the volume of inorganic slag is less than 5% of the volume of raw garbage. The solids in the inorganic slag are metals, ceramic sheets, bricks and tiles, glass, etc., and the metal objects are sorted and recovered; the remaining inorganic slag is sorted and used as cement raw materials; the combustion of organic matter produces high-temperature flue gas, dust and incineration gas containing calorific value and sends it to the pre-calcination furnace of the cement kiln for heating and degradation of dioxins.
