Research Project Summary Information

Cascade Economizer(ST10959)

Beech-Nut Nutrition Corporation


Beech-Nut manufactures food products and is currently building a new facility in the Town of Florida. Like many commercial and industrial operations in New York State, they depend on steam to provide thermal energy. Economizers are used to heat feedwater in large high pressure boiler plants, and are an effective means to recover waste heat from flue gases. Condensing economizers are limited because acidic condensate can formulate in improperly designed units and they usually depend on material selection or surface treatment to prevent corrosion. This is not compatible with high flue gas temperatures and condensing economizers are not directly applicable in all circumstances. Enough heat has to be extracted from the exhaust to prevent damaging the condensing economizer’s surface treatment.

Project Description

This project will install the hybrid economizer, an economizer that includes elements of both a traditional non-condensing and condensing economizer(s) in a cascade arrangement, in the Beech-Nut factory in Florida, NY. The project will assess the technological feasibility, and design, install, commission, and monitor the performance of the application of the hybrid economizer.


Some of the benefits for this project are fuel savings of up to $400,000 for each boiler (gas price of $12 per dekatherm), reduced emissions due to offset thermal loads, and a payback period of 2-3 years.
