Waste incinerator to regenerate energy

Waste incinerator to regenerate energy

I. Introduction
A waste incinerator to regenerate energy is equipment that uses waste as fuel inputs to produce energy and combines modern technologies to help disinfect, and treat toxic substances generated in the process of burning. This is one of the effective solutions in waste treatment to reduce harm to the environment. Incinerators will dispose of waste at high temperatures, up to over 1050°C. The heat from the hot gas after the combustion chamber will be used to boil water in the boiler to produce high-pressure steam for generators, building heating systems, or other purposes. The energy provided from 5-7 tons of waste can be equivalent to the energy supplied from 1 ton of fuel oil.

II. Working procedure of waste incinerator to regenerate energy:
Fundamentally, the operation of a waste incinerator to regenerate energy is the same principle as a normal incinerator (Waste pyrolysis – Exhaust gas treatment). The difference is that, at the heat exchanger cooling the exhaust gas, the heat from the exhaust gas after the combustion chamber will be reabsorbed and reused in the cooling tower. Coldwater is led through a closed circulating steel pipe system in direct contact with the hot air stream after the combustion chamber. The water will be heated to boiling point and converted to superheated steam. High-pressure hot steam can be used to lead through turbines that run generators, for medical autoclaves, or for circulation in building heating systems,…. In addition, hot water can be used directly for household activities. The efficient heat reuse process can reach 70-80% of the combustion energy.

III. Advantages of the waste incinerator to regenerate energy:
– Waste treatment, make use of waste sources effectively to convert them into fuel
– Thoroughly treat exhaust gas and toxic substances generated from waste incineration according to Vietnam regulations.
– Take advantage of the generated heat to serve multiple purposes such as running a generator; heating system, building hot water; autoclave drying systems in industry…
