Low-NO X hot water boilers for complex district heating grid.

Two Bosch hot water boilers, each with 20 MW, have
been in operation in the new Pieter Wiersma heating
plant in Lent (the Netherlands) since 2015. Thanks to
innovative boiler and burner technology, it is one of the
cleanest plants of this type in Europe. It feeds heat into
the Nijmegen district heating network and supplies up
to 14,000 households. The base load is generated by
means of heat from a waste recycling plant. The Bosch
boilers support the district heating network at peak
loads in winter and serve as back-up in emergencies.
This ensures that the heat supply to the inhabitants is
uninterrupted.
Highly modern and innovative: the Pieter Wiersma heating plant
in Lent.
