Waste-to-energy (WTE) is the process of generating energy in the form of electricity and/or heat from the incineration of waste. WTE is a form of energy recovery. Most WTE processes produce electricity and/or heat directly through combustion.
Incineration, the combustion of organic material such as waste with energy recovery, is the most common WTE implementation. The combustion of waste may produce many pollutants that must be treated and reduced before the stack, to avoid environmental contamination.
In such systems is necessary to have a combustion system properly designed: the role of the burner (or burners) is to heat up the furnace and the combustion chamber during the start-up phases until a temperature suitable for the introduction of waste and the maintenance of the flame stability by the same. Once the combustion chamber has reached the correct working temperature, the burner is moved in stand-by position and protected from the flame and flue acid gas generated by waste combustion. The burner will return in firing position only if the temperature in combustion chamber reaches the limits imposed by law, or to shut-down the incinerator.
Depending from incinerator’s characteristics and Client’s request we are able to design such combustion system complete with all ancillaries equipment (combustion air fan, oil & gas skids and so on) and control system. Usually, for the above application, we use “M” or “DM” burners type.
