PLANT MANAGEMENT
part of its green electricity using an on-site photovoltaic system. There are plans for further expansion in the future, and a wind turbine will also support electric power generation at a later date. If there are fl uctuations in the amount of electricity produced owing to the weather, or when there are peak loads, a reliable back-up is needed. The solution to this is a highly eff icient, gas-fi red UL-S steam boiler, which supplements the Bosch system by producing another 5 t/h of steam. The convertibility of such boiler systems will off er fl exibility if, in the future, other renewable energy sources become available in the infrastructure. The generated steam is used in
the corn cooking process to heat huge containers. Corn is the main ingredient in tortilla chips and up to 15,000 tonnes are processed every year. This makes the reliable supply of process heat all the more important. The diff erent systems and types of energy need to be combined in a way that works holistically and the control system, produced and confi gured by Bosch for this project, has been set
PepsiCo generates part of its green electricity from its on-site photovoltaic system
up accordingly. The incorporated software not only controls the complex steam processes, but also ensures intelligent communication between the systems. This is made possible by the smart multi-boiler control. In addition to the hybrid steam boiler system, Bosch also supplied two gas-fi red UT-L boilers for heating the buildings and production halls. The total heat output is around 6 MW and the technology has an eff iciency
level of 99%, enabling energy savings and low-emission operations. With its multivalent approach, Bosch succeeded in fi nding a fl exible solution for PepsiCo that meets the company’s current and future sustainability goals.
