Arrow Linen Supply Company Benefits From Cogeneration

Arrow Linen Supply Company located in Brooklyn, NY has been benefiting from their 300 KW cogeneration power plant. The CHP plant is comprised of two (2) modular cogen units of 150kW each. Unit configuration is low emission type natural gas fired engine sets with Induction Generators. Waste heat from the units is recovered in the form of hot water. This waste heat is used to preheat make up water for the domestic hot water tanks and steam boilers (off setting existing gas usage). The plant is located on the roof of the existing structure near the main gas service entrance.

The electric feed from the CHP plant runs back to the building electric service. The building electric service was modified to allow proper connection of the CHP power.

A complete micro-processor controlled utility parallel system was provided to meet all requirements of the local utility, CONED, interconnection guidelines. The CHP plant is designed to operate in parallel with CONED. In the event of a partial or full failure of the cogeneration plant the facility can receive full power from the utility.
