Safety equipment

In correspondence with the statutory and normative
rules, the key components CHP and 4-draught boiler are
equipped with the required safety equipment.
For connecting the bypass function (
page 34) a functionality has been defined by the German
Technical Control Board TÜV that is described in the
Technical Paper TI 041: "Requirements to the waste heat
generating power unit in conjunction with a downstream
3.3.6

System control

The superordinate control of the combination CHP and
4-draught steam boiler should be mainly effected by the
Bosch control system MEC system.
MEC System
The system control MEC System is a possibility for
intelligently controlling the combinaton CHP with
4-draught steam boiler. MEC System controls the
subsystem CHP and 4-draught steam boiler and
optimally integrates it in the overall energy generation
system on site.

All documents and licences required for receiving a TÜV
chapter 3.4.1, certification exist and are provided by Bosch. Bosch
provides during quotation phase a P&ID (piping and
instrumentation diagram) that is released for external
use, exemplary installation drawings in PDF and DXF as
well as comprehensive quotation texts.
A control with MEC system is possible, but the system
benefits generated by MEC, that are presented in the
following chapters, cannot be achieved.
Benefits of the control are among others:
• Optimum activation of devices while maintaining the
operating conditions
• Integration of device controller via Modbus interface.
The amount of transferred data points allows for
optimum control and visualisation.
