A new Bosch steam boiler system has become operational at German food producer Hans Henglein und Sohn’s site and will help the company achieve sustainable and environmentally friendly processing of its potatoes and dough products.

Plant construction company Petry installed the new boiler system technology on site.

For the investment in the efficiency-enhancing and CO₂ reducing components, the company secured subsidies amounting to 30% from state development bank KfW.

With the integration of the Bosch MEC Optimize digital assistant as part of the efficiency project, Henglein was able to easily plan future maintenance, rectify faults or optimise efficiency during operation.

The assistant immediately detects energy losses, higher emissions and critical states, as well as proactively offers the operator recommendation for actions.

Bosch noted that intelligent algorithms can collect and interpret the operating data, assess the components’ service life and analyse water values.

Bosch sales engineer Dr Alexander Vollet said: “The efficiency components used, such as two flue gas heat exchangers, achieve particularly positive effects with savings in fuel and CO₂ emissions of 15%.

“While the efficiency level of the old boilers without economiser was around 85%, the new Bosch steam boiler now achieves over 100%, thanks to efficiency and condensing technology.”

The entire design of the UL-S steam boiler used at Henglein is based on high energy efficiency. The boiler is capable of reducing NO_x emissions by around 35% compared with its predecessors.

The new Bosch boiler system also optimises processes and significantly helps to reduce the carbon footprint.

Henglein managing director Norbert Henglein said: “For us, the topic of environmental friendliness plays a key role, which we are continuously improving with energy-efficient installations and transparency of all energy flows.”
