State-of-the-Art Waste Treatment Plant Delivered to Hirakata City

Tokyo, February 9 — Kawasaki Plant Systems, Ltd. announced today that it has delivered a state-of-the-art waste treatment plant to the City of Hirakata in Osaka.

The plant consists of Kawasaki’s proprietary cutting-edge stoker type incinerator and fuel-type ash melting system. Aiming to be the greenest in the world, these plant components have been designed to leave a minimum footprint on the environment. The plant is also equipped with a steam turbine power generator that utilizes waste heat to supply the power that operates plant facilities.

Technological features of the stoker type incinerator include:

(1) The Kawasaki Parallel Flow Stoker Type Incinerator

The furnace’s shape allows the flame to flow parallel to the direction in which refuse is incinerated, facilitating complete combustion with less air (or at a lower air ratio) and reducing more combustibles in the bottom ash compared with conventional incinerators.

(2) The Kawasaki Water Cooled Grate

The water cooling system for the grates that feed refuse at high temperature conditions improves the durability of the incinerator.

The plant not only meets strict standards for dioxins, exhaust gas, effluent emissions, fly ash leachate and slag but also employs the abovementioned technologies to reduce environmental load including soot/dust, hydrogen chloride, and sulfur oxide emissions.

This plant is the 161st waste incineration system delivered by Kawasaki. It is a model plant combining the latest practical technologies that Kawasaki has been developing for more than 40 years.
