A SRU incinerator is an oxidation-reduction reactor for the recovery of elemental Sulphur from H2S rich waste gases. The first stage of the so called Claus process, is the complete free flame oxidisation of typically 1/3 of the H2S to SO2 in a reaction furnace (H2S + 1½ O SO2 + H2O). The SO2 and the then remaining H2S undergo the Claus reaction both in the reaction furnace and in a series of catalytic reactors (2 H2S + SO2 3S + 2 H2O) resulting in the overall chemical reaction H2S + ½ O H2 + S. Key Features One combustion chamber with mixing wall Part of the waste containing H2S is injected through the burner, the remainder before the mixing wall. The burner is a robust Multifuel design suitable for the combined combustion of different waste gas and gaseous or liquid support fuel streams. The mixing wall ensure the waste and combustion gases combine and also ensures a uniform temperature profile to improve the overall efficiency of the reaction. Key Advantages - Sulphur recovery – Ultra-low NOx combustion possible – Complete oxidisation of all hydrocarbons – No CO formation – Complete odour destruction – Destruction efficiency over 99.99% – For waste air/gas streams containing a high percentage of H2S

A LedeNOx incinerator is an oxidisation-reduction reactor and is the ideal design to achieve low NOx emissions whilst burning waste streams that contain Ammonia and bound Nitrogen. Part of the waste stream containing Ammonia is oxidised and forms NOx in the process. This NOx is then reduced by injecting the remaining Ammonia rich waste stream, where the Ammonia is used to promote a non-catalytic deNOx reaction and reduce NOx to Nitrogen and water. Key Features One combustion chamber with two mixing walls Part of the Ammonia containing waste is injected through the burner, part between the mixing walls. Part of the Ammonia is oxidised to form NOx, whilst the remaining Ammonia is used to react with NOx to form N2. The mixing walls ensure that the waste and combustion gases are mixed and also ensures a uniform temperature profile to improve the overall efficiency of the deNOx reaction. Key Advantages No need for SNCR or SCR deNOx to meet emission limits Ultra-low NOx combustion of waste streams with high bound Nitrogen or Ammonia contents. Complete oxidisation and destruction of all hydrocarbons No CO formation Complete odour destruction Destruction efficiency over 99.999%

Rotary kiln incinerators are the workhorse of industry to burn solid waste in combination with sludge, waste gas and/or waste liquids and where the rotating motion transports the solid burning waste through the incinerator. Ashes are collected at the end of the rotating kiln and then combustion gases are completely oxidised in the static post combustion chamber. Rotary kiln incinerators typically feature different types of solid waste feeding systems for the bulky solid waste, containers and drums such as feeding screws and ram feeders. Waste gases and liquids are either injected into the rotary kiln, or the (vertical) post combustion chamber behind the rotary kiln. It provides for flexible and versatile incineration technology, but is characterised by a lower thermal efficiency with the associated higher operating and maintenance costs. Key Features Rotary kiln furnace with pre-set inclination and variable rotation speed. Labyrinth type seal with cooling and/or flushing with inert gas Different feeding systems for solid waste, waste liquids and waste gases Can be operated in a reducing or oxidizing environment Different drive mechanisms such as chain or direct drive, depending on the size of the kiln and the capacity Key Advantages - Robust and flexible design to burn a wide range of waste fractions – Proven technology – Destruction efficiency over 99.999% and less than 3% carbon in the ashes – Low NOx and CO emissions possible – Flue gas treatment train needed to meet acid, heavy metal, dust and PCDD/F emission levels
