A confidential client retained EAD to provide engineering services related to installing a 5.3 MW gas turbine and heat recovery steam generator (HRSG). This installation includes a new building to house the HRSG, 4160V switchgear, 480 V MCC, and turbine accessories. The system also includes a 1000 Hp, 4160 gas compressor. A new building with 13.8 kV switchgear including protective relays was also included to interface with the local utility and meet the local utility’s distributed generation system interconnection requirements.
The completed combined heat and power (CHP) system will take advantage of the biogas produced by the anaerobic digesters to generate enough electrical power to meet the ethanol facility demands. The HRSG will produce24,000 lbs. per hour of steam at 150 psig to augment the plant’s process boilers.
