Case study details Cummins role in Broadcrown biogas combined heat and power project


A new case study highlights the role that Cummins Energy Solutions Business and Cummins Generator Technologies played in the implementation of a biogas combined heat and power solution for a major sewage treatment works in London, UK. Cummins QSV91 lean-burn gas engines are at the heart of three Broadcrown generator sets that provide power to a sewage treatment works while simultaneously providing heat for the site’s processes.

Broadcrown is a leading UK independent manufacturer of power generators and generation systems from 6 kVA through to +30 MVA. It was Broadcrown’s task to design and supply a cogeneration solution to Riverside Sewage Treatment Works, owned and operated by utility company Thames Water.

The project was innovative and sophisticated. As well as renovating four existing digesters, the work also involved the provision of a Thermal Hydrolysis Plant, fed by high-temperature steam from a boiler heated by the biogas engines’ exhausts. Broadcrown’s design for the project also involved fire protection through a water mist system, jacket water heat recovery, a full header tank system, standby generators and a control system to interface with the site-wide power management system.

Three Broadcrown Combined Heat and Power generator sets were installed, each equipped with Cummins QSV91 lean-burn gas engines and Cummins Generator Technologies STAMFORD ® alternators. All three Broadcrown units were housed in custom-designed acoustic enclosures, built on site.
