Descr ipt ionThe Iserlohn waste incineration plant was first commissioned in

1970. Between 1994 and 1996, the plant was extensively up-

graded and optimized, and is now one of the most modern

plants of its kind in Europe. Waste combustion is done in three

lines – two with a throughput of 8 tons/h, and one for 16 tons/h.

The steam produced during incineration drives two turbogenera-

tors for electric power. After leaving the turbogenerators, the

residual heat in the steam is used for district heating (combined

heat & power CHP).

Right from the start ME-Automation Projects, formerly known as

KH-Automation Projects, has been responsible for the CHP

plant‘s automation – from installation of the first analog measu-

rement & control system up to the present modern process ma-

nagement equipment. In the course of these modernization

measures, a supervisory process management system (PMS

68000) was also installed. Monitoring, operation, and control of

the refuse incineration plant are effected via the process ma-

nagement system and an independent back-up system in the

central control room. Thanks to these two fully separate opera-

ting systems, the plant‘s availability and operational safety were

increased significantly.

Due to tighter environmental regulations, it was necessary to

renew and extend the waste gas cleaning installation in 1996.

For this project stage, ME-Automation Projects not only supplied

the new process control & automation equipment (PMS 68000

and P8) complete with field instrumentation, but also the entire

electrotechnical system.

Control and sequencing operations of the complex plant are

handled by a total of 40 automation stations. These individual

control modules allow operation in the field, as well as manual

operation via a mosaic panel in the central control room. In or-

der to ensure an optimum burnout of the waste with maximum

energy utilization, a particularly effective combustion control

system was developed and installed in cooperation with the

plant‘s owner/operator.

During further construction stages (2008 - 2009), the superviso-

ry control system PMS 68000 installed in 1996 was replaced

with the modern PMSX®pro process management system. Here-

by, the investments of the previous construction phases were

preserved by means of an efficient migration concept. Similarly,

the control room was also redesigned in accordance with the

latest ergonomic aspects during these modernization measures.

A large-screen display with ten video cubes supports the opera-

tors and provides detailed process surveys and visual insertions

at a single glance.

During the following years, the discontinued Philips P8 systems

were replaced by state-of-the-art, redundant Mitsubishi System Q

automation systems.
