High Boiler Efficiency because of less<br />
energy loss from flue gas
Basic Concept for Waste Treatment<br />
High energy efficiency <strong>and</strong><br />
economical<br />
High energy conversion<br />
efficiency by high temperature<br />
<strong>and</strong> less flue gas.<br />
Highly optimized system of ash<br />
melting by refuse retaining heat<br />
Reduction of number of<br />
operators <strong>and</strong> running expenses.<br />

The operating condition is able to be<br />
checked by KES in real time.<br />
In case of not good condition, KES can<br />
make appropriate suggestion to<br />
optimize the operation, for staffs <strong>and</strong><br />
operators on site, early.<br />
Operation data which are gathered<br />
through the system is able to be<br />
analysed by KES engineers. The<br />
analyse result can contribute greatly to<br />
optimize the operation via PDCA cycle.
