Employed technology for waste incineration
Most of our incinerators work thanks to a pyrolytic system based on planned combustion. Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen in order to obtain products gasification and not fully oxidized particles.
The main aspect of pyrolysis is that the gaseous products obtained, can be themselves burned. Therefore it’s necessary a small quantity of combustible material for their complete combustion in a second chamber.
This process guarantees waste incineration and the complete elimination of fumes and smells. The advantage is the reduction of fuel consumption of more than 20% in comparison with common incinerators, because the air in the incineration chamber is three times lower.
Thermal decomposition is obtained through introduction by blowers of the third part of stoichiometric mass of air in the incineration chamber. Therefore, the combustion in the next area develops gaseous products. These products pass through waste material, increasing temperature and causing their gasification.
These are complex reactions, existing local conditions both of oxidation and reduction. In this phase oxygen is reduced at minimum. At the same time, the refractory material covering the incineration chamber gets warm; the heat passes through waste material and causes a thermal flywheel which generates flying particles gasification.
Due to the lack of oxygen useful for their combustion, these particles are composed of carbon monoxide and gaseous hydrocarbon. The remaining solid particles are full of carbon and come out from degasification. They incinerate and are drawn out at the end of the process. The complete combustion of gas produced is obtained in the post-combustion chamber thanks to a pilot light and stoichiometric air.
With gas ignition, temperature in the post-combustion chamber becomes high. Air introduction causes the complete combustion of all gases coming up from incineration chamber..
Employed Technology for Heat Recovery
Heat recovery from fumes going out into the atmosphere
Fumes washing chamber, fabricated in stainless steel AISI 304 or in carbon steel and furnished with refractory material with a high heat transfer coefficient, crossed by hot gas coming from post combustion chamber, works also as heat exchanger for energetic recovery. Between it and the destroyer surface, air is blown in through an electro valve.
The air preheats due to the contact with the heat surface of the washing chamber, recovering with zero costs heat by fumes.
Heat recovery from washing water
Powders removal plant is furnished with an immersion heat exchanger for heat recovery from washing waters. Waters, heated by fumes contact, come back into the sedimentation basin. Therefore hot water can be used at any time for washings, to clean the floor where the plant is set and to feed radiator plants.
Employed technology for powders removal
Powders removal plant, mod. WET SCRUBBER are composed by a destroyer set on the top of post combustion chamber and connected through a conduct with gas coming up from post combustion chamber. Fumes depuration takes place through water sprinkled under high pressure, which wets powders floating in fumes and drains them away.
Washing water, mixed with powders, falls down into a sedimentation basin, made up in carbon steel sheets. Once impurities have been settled, water is recovered and used again through an electric water pump. The settled muds on the bottom of this sedimentation basin can be drained thanks to a specific valve.
Being a closed circuit system, there’s no need to change washing water. A float valve provides to automatic reintegration of evaporated water. The employment of a washing water recovery system allows low water consumption. Any problem or damage of the washing plant is signaled by an acoustic and visual alarm.
