A municipal solid waste incineration plant in Hamura, Tokyo, was using powder-activated carbon injection to control dioxin/ furan emission. The plant management needed a solution to two simultaneous challenges: Increasing the facility’s waste incineration capacity by 14 % while mitigating the surrounding neighborhood’s concerns of high dioxin/furan emission.

At an energy to waste facility in Kochi, Japan, power was generated by incinerating municipal waste using a stoker furnace, which incorporated pollution control units at the downstream. After heat recovery, the flue gas was further cooled down to 150 °C for the effective carbon adsorption of dioxin/furan. The gas was then passed through a filter baghouse to remove particulates. Finally, the gas was reheated to 210 °C for tail-end NOx reduction by an SCR tower.

The construction firm A&E was competing for a new MSW incineration facility at Okayama Prefecture (Japan). One of the facility’s core needs was to meet regulations for post-incineration emissions. As part of the bidding process, A&E committed to finding the best-available technologies to meet the project’s various technical scopes, including controlling post-combustion dioxin/furan emissions, all while minimizing the initial investment and ongoing operating costs.

The local government of a city in the Fukui prefecture (Japan) needed to revamp its MSW incineration facility to simplify operations and reduce costs. A key factor for the revamped facility was a potential replacement for its existing pollution control unit, which used a fixed-bed activated carbon with ancillary fire protection system to reduce post-incineration dioxin/furan emissions.

Carbon black is produced, sized and conveyed in a powdered form. Dust collectors (baghouses) are used to efficiently collect the carbon black particulate and to control fugitive emissions. The manufacturer faced the need to increase airflow through the reactor (to increase production) and wanted to extend the service life of the filter bags in order to save costs.

In 2013, the city of Villefranche (France) requested that its municipal waste incinerator reduce its emission levels to < 80 mg/Nm³ NOx and < 10 mg/Nm³ NH₃, especially necessary given the plant’s close proximity to the city of Lyon. However, the plant didn’t want to compromise its incineration capacity in its efforts to reduce emissions.

The HESTAMBIENTE Municipal Waste incinerator, part of HERA group, is located in Padova (Italy). Due to tight regulations, the incinerator needed to significantly reduce its line 1 NOx emissions.

The waste incinerator CEDLM in Limoges (France) was proactively looking for efficient solutions to reduce NOx emissions to a 80 mg/Nm³ level, making them eligible for emission-related tax benefits.
