2.5.2 3-draught waste heat boiler for use of waste heat only
If, due to very high waste heat mass flow or very high flue
gas temperatures, the limits of use of the waste heat
boiler HRSB should not be sufficient, a
3-draught waste heat boiler can be used for waste heat
utilisation only.

2.5.3 System extension with peak load boiler
If the motor waste heat provided by the CHP module is
not sufficient for the heating water supply or if it shall be
supply also redundantly to the CHP module, the system
can be extended by a boiler for covering these loads.
