Disposing of all kinds of garbage and waste, especially urban waste (domestic, hospital, and sanitary), industrial, petroleum, and petrochemical waste in the current landfill sites, has exposed the soil to a wide range of hazardous and toxic substances, and also water pollution. Underground can make a significant contribution to greenhouse gas emissions. Gasification of waste is one of the new methods of waste disposal, during which, while making the waste harmless, its organic parts turn it into usable gas as a source of clean energy or the raw material for the production of other chemical compounds. Among the types of gasifiers, plasma gasifiers, by producing a plasma with a temperature of several thousand degrees, decompose the chemical bonds in waste organic materials into their constituent atoms, which are further recombined into small molecules such as hydrogen, carbon monoxide, water and carbon dioxide. Inorganic wastes such as metals, glass and ceramics are removed from the machine in the form of molten materials and slag with the ability to be separated, which are reused as side products after cooling.
In the Behyaar Sanat plasma waste incinerator, after an initial processing and separation of recyclable materials (magnetic, non-magnetic metals and glass if the customer wishes), the waste is crushed into smaller pieces and upon entering the first gasification chamber, by the steam and air above Hot loses about 60% of its volume in the form of gas. The rest of the waste, including the remaining ash, organic parts and inorganic parts, enter the main gasification chamber, i.e. the plasma chamber, and under the influence of several thousand-degree plasma created by graphite electrodes under the influence of a direct electric current, they are completely transformed into gas, material and molten slag respectively. After cooling, non-metallic molten slag can be used in construction, road construction or other industries. The produced gas, which contains a high percentage of hydrogen and carbon monoxide, is sent to the relevant units after cooling, purification and removal of possible acid gases for use in the production of electricity, fuel and chemicals with added value (ethanol, methanol and pure hydrogen). In the plasma gasification technology, in the best case, about 1000 kWh of electric energy is produced for each ton of municipal waste, which fully supplies its own electricity consumption in capacities above 30 tons per day. A waste incinerator unit of 100 tons per day can produce 5000 kW of electricity, of which 2000 kW is consumed by the device itself and the remaining 3000 kW is transferred to the national electricity grid for sale.
