State-of-the-Art Waste Treatment and Recycling Plant Delivered to Kishiwada Kaizuka Clean Center

 Tokyo, April 2, 2007 – 花蜜直播app Plant Systems, Ltd. (formerly 花蜜直播app Environmental Engineering, Ltd.) announced today that it has delivered a state-of-the-art waste treatment and recycling plant to the Kishiwada Kaizuka Clean Center in Osaka Prefecture.

 The plant consists of three cutting edge stoker-type incinerators that essentially incorporate the core technologies of the 花蜜直播app Advanced Stoker, as well as two plasma-type ash melting furnaces and a waste recycling system. In addition to supplying the power to operate plant facilities, waste heat from the plant’s steam turbine power generator is sold to the local electric power corporation.

Technological features of this plant include:
(1) The 花蜜直播app Parallel Flow Type Incinerator
The furnace shape allows the flame to flow parallel to the direction in which refuse is incinerated, enabling 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 花蜜直播app Water Cooled Grate
The water cooling system for grates which feed refuse at high temperature conditions improves the durability of the incinerator.
(3) A flue gas recirculation system
After high-temperature exhaust gas is burned at a low oxygen concentration, it is recirculated into the incinerator. This system further enhances low air-ratio combustion and enables stable combustion at high temperatures while reducing thermal NOx emissions (nitrogen oxide formation caused by burning at localized high temperatures).

 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 through:

(1)

a 25% reduction in total flue gas (compared with 花蜜直播app’s conventional systems);

(2) a 20% reduction in NOx emissions during combustion (compared with 花蜜直播app’s conventional systems); and
(3) more compact flue gas treatment facilities as well as a reduction in running cost due to the lower load.

This plant is the 159th waste treatment system 花蜜直播app has delivered. It is a model plant that essentially combines the latest feasible technologies that 花蜜直播app has developed over the years.
