MHIEC Completes Improvement of Core Equipment at Municipal Solid Waste Incineration Facility in Sendai City
5-Year Project at Matsumori Waste-to-Energy Plant Has Extended Service Life and Reduced CO2 Emissions
– Renewal of core centers, consisting of devices for combustion, combustion gas cooling, and exhaust gas treatment will add to long-lasting steady combustion and operation
– CO2 decrease rate of 12.1% attained, surpassing the preliminary target worth
Matsumori Waste-to-Energy Plant
TOKYO, Apr 22, 2026 -(JCN Newswire)- Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd.(MHIEC), a part of Mitsubishi Heavy Industries(MHI )Group, has actually just recently finished the enhancement of core devices for Matsumori Waste-to-Energy Plant, a local strong waste incineration center in Sendai City. MHIEC got the agreement for the task from Sendai City in 2021, with work performed over a five-year duration from financial 2021 to financial 2025. The restoration of the stoker-type incinerators( 1) with overall processing capability of 600 heaps daily (tpd) will extend the functional life of the center and minimize CO2 emissions.
The Matsumori Waste-to-Energy Plant was initially developed and built by MHI, and finished in August 2005. It makes up 3 systems of stoker-type incinerators, each with processing capability of 200 tpd, plus associated devices, providing power creating capability of 17,500 kW.
Under the repair work, upgrades have actually been made to significant devices superannuated after more than 15 years in operation, to attain steady combustion and operation over the long term. In addition, the thermal effectiveness of the boiler has actually been boosted with the intro of EGR-PLUS ®, a brand-new combustion control system utilizing an exhaust gas recirculation innovation.( 2) Further, a part of the soot blower that gets rid of ash from the boiler tube has actually been altered from a standard steam type to a pressure-wave (shock pulse) type,( 3) lowering the quantity of steam utilized for ash elimination and permitting more steam for power generation, therefore improving power creating capability. These restorations have actually attained a decrease in CO2 emissions of 12.1% each year.
MHIEC took control of the waste treatment plant organization from MHI in 2008, obtaining technological advancement abilities in ecological systems and broad-ranging know-how in the building and construction and operation of waste management centers both in Japan and overseas. This substantial experience enables MHIEC to supply extensive options, from plant building to operations. Moving forward, MHIEC will continue to proactively make propositions to extend the life of existing waste treatment centers, take procedures versus international warming, and minimize lifecycle expenses (LCC) such as upkeep and management expenses to add to the decarbonization of energy through the collection of energy from waste.
(1) A stoker-type incinerator injects air from underneath heat-resistant fire grates, blending the waste and other product by pressing it up, and enabling effective incineration. It is the most typical system utilized for community strong waste.
(2) Exhaust Gas Recirculation (EGR) is an innovation to send out exhaust gas from the incinerator back into the combustion chamber, promoting total combustion and lowering nitrogen oxide (NOx) emissions. MHIEC’s EGR-PLUS ® is a leading-edge combustion control system that integrates EGR with low air ratio (the quantity of air in fact sent out to the incinerator divided by the minimum quantity of air in theory needed for incineration) combustion innovation to lower the ecological effect, and attain a steady boost in the quantity of electrical energy offered.
(3) A pressure-wave (shock pulse) type soot blower is a gadget that eliminates ash from pipelines by sparking a mix of methane and oxygen and shooting it into the combustion chamber from an injection nozzle, developing a pressure wave that separates ash deposits and triggers great vibrations on the pipeline surface area.
