​217. Optimizing brewing process heating energy management with modular on-demand boiler systems

​Sustainability Session

Jason P Smith, Miura North America, Inc.
 
ABSTRACT: This presentation illustrates how emerging modular on-demand steam boiler technologies are well suited to address the energy and environmental challenges facing the North American brewing industry. Breweries, both startups and well established, face increasing challenges of minimizing the economic and environmental impacts of the brewing process on their production while achieving a consistent high quality brew. Boilers account for nearly half of industrial energy consumption and represent one of the most energy intensive systems involved in the brewing industry. While not always the most visible component of the brewing process, the utility side of brewing can represent an economic hurdle on the front-end via capital outlay and an energy management challenge during production due to process load variability as brewing, pasteurization, and CIP processes ramp up and down. Two key concepts—modularity and on-demand response—represent innovative strategies for both minimizing the initial capital investment tied to utility systems while optimizing boiler performance with enhanced energy management capability more precisely matched to process requirements. Modularity enables a startup brewery to minimize the up-front investment in its utility by purchasing only the boiler capacity needed with the flexibility to increase steam capacity with additional modules as production increases. On-demand response out of the utility enables the brewery to precisely match the boiler output to the process requirements at any point in time, eliminating significant energy losses associated with boiler part-load and perpetual idling operation during process lulls. In the same way that tank-less/instantaneous water heaters are enabling increased energy efficiency in the residential sector, compact modular on-demand boilers are poised to support the same kind of transformation in the industrial sector. Moreover, given the large amount of energy consumed and the sharp minute-to-minute variations in process steam demands in the brewing industry, on-demand steam generation can play a significant role in increasing energy efficiency while reducing a brewery’s carbon footprint.
