MHIEC Receives Highest Award at 48th Outstanding Environmental Systems Awards

– “METI Minister’s Award” Presented for Innovative V-type Stoker System Uniquely Produced by MHIEC Achieving High Efficiency and Environmental Excellence –

– Innovations enable stable incineration and reduced level of diverse wastes; efficient incineration using radiant heat plays a part in easing environmental load

– Incinerator downsizing enhances freedom in planning installations at sites with limited space

TOKYO, July 27, 2022 – (JCN Newswire) – Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC), part of Mitsubishi Heavy Industries (MHI) Group, has received the “Ministry of Economy, Trade and Industry (METI) Minister’s Award” at the 48th Outstanding Environmental Systems Awards, hosted by The Japan Society of Industrial Machinery Manufacturers (JSIM), because of its newly developed stoker-type waste incinerator(1). The “METI Minister’s Award,” the best award presented by JSIM, cited the incinerator’s innovative V-shaped structure and low loss on ignition(2). An awards ceremony happened at the Kikai Shinko Kaikan building (Minato-ku, Tokyo) on July 26.

JSIM’s Outstanding Environmental Systems Awards were inaugurated in 1974, with support from the METI (in those days, Ministry of International Trade and Industry), to market research and development of environmental protection technologies and promote the adoption of outstanding environmental systems. Nominations for the awards are submitted by environmental system manufacturers and environmental engineering firms nationwide, and the award recipients are selected by way of a committee of experts predicated on criteria including innovativeness, economic merit and future potential. As well as the METI Minister’s Award, other awards are presented in the names of the Director-General of METI’s Industrial Science and Technology Policy and Environment Bureau, Commissioner of METI’s Small and Medium Enterprise Agency (SMEA), and the JSIM President.

MHIEC’s V-type stoker system for waste incineration with forward acting grate-bar incorporates improvements and advances from the business’s earlier conventional kind of stoker. It had been developed to supply stable incineration and reduced level of waste with wide-ranging properties and in diverse states, to donate to reducing environmental load. The stoker structure and incinerator shape have already been optimized therefore the surface of the stoker grates is fond of the biggest market of the flame during all processes: drying, combustion and post-combustion. The foremost benefit produced from these innovations may be the capability to receive radiant heat efficiently because the waste is combusted, enabling a decrease in the proportion of residual waste in the ash left after incineration.

Efficient usage of radiant heat also enables downsizing of the stoker, saving space for boiler house which typically requires significant space inside a waste-to-energy plant. These improvements enhance freedom in planning installations at sites where available space is bound. MHIEC delivered its V-type stoker system which plant went into commercial operation in January 2021 and is running smoothly around today.

MHIEC has strengths in developing environmental system technologies cultivated over a long time, and today, after receiving the most recent JSIM award, the business renews its determination to use those strengths to the construction and operation of waste-to-energy plants that donate to alleviating environmental impacts. In these ways MHIEC can make significant contributions to reaching the SDGs (Sustainable Development Goals), solving global environmental issues, and realizing a carbon-neutral society.

(1) In a V-type stoker system, waste is dried, heated, mixed and combusted since it moves along on a grid of fire grates manufactured from heat-resistant castings.

(2) Loss on ignition represents the weight ratio of the unburnt content in the dried bottom ash.
