An Efficient Boiler Room: Boilerroom Equipment Inc. (BEI) Provides a HeatSponge Economizer

As manufacturers’ representatives for “products that produce results,” Engineered Energy Equipment (EEE) specializes in selecting the best equipment to meet our clients’ needs.

We can meet these objectives with the addition of an economizer. Specifically, the new generation of boiler economizers:  the HeatSponge by Boilerroom Equipment, Inc.

BEI is a division of Thermal Energy International that engineers and manufactures ASME pressure vessels for many different industries. They’re also known as the innovator behind the HeatSponge brand of boiler economizers. These are the most modern steam boiler economizers available to the global industry today.

When asked why EEE recommends the HeatSponge, EEE Director of Sales Kevin Warren explained. “Because without requiring ASME welds, it means repairs are easier, and usually, no code inspection is required—that saves time and money upfront.” 

The HeatSponge Difference: An Efficient Boiler Room

Firstly, the BEI HeatSponge product lines maximize heat transfer via a heat exchanger. It transfers energy from an air stream into a liquid stream.  Most economizers use the flue gas that exits in the boiler to preheat boiler feedwater. Because most natural gas or fuel oil-fired boilers will utilize economizers to absorb heat better.

Kevin Warren also said that the addition of a boiler economizer often arises when start-up plans are made, but he recommends adding a BEI HeatSponge after a boiler is in place.

“We are often asked how boiler rooms can be more efficient, and often the conversation starts with how can we use less fuel?” Warren explained, “Wasted heat means wasted money because by extracting/recovering heat, it means you use less fuel.”

Saving Money with an Economizer

Recovering heat in an economizer is based on the Law of Thermodynamics. The flue gas exiting boilers contains a great deal of energy that cannot be recovered inside of the boiler itself. The gases inside of the boiler can’t be a temperature less than the temperature of the saturated water inside of the boiler. The HeatSponge product lines maximize heat transfer.

Greater efficiency means enhanced return on investment (ROI) in the boiler room operation. Warren explains that the fuel efficiency is gained by capturing the heat where the flue gases exit the boiler.

“The gas heat is pushed through the economizer via the stack before it’s expelled into the atmosphere.  Those gases would otherwise enter our atmosphere increasing the carbon footprint and decreasing the heat capture,” said Warren.

HeatSponge steam boiler economizers reflect the global state-of-the-art for heat recovery. But these High-Value-Added economizers are highly efficient and easily maintainable, providing for a very long and productive life. Among the latest innovation are the Two-Stage HeatSponges which allow for optimum heat recovery by integrating two separate heat exchangers into one casing and can increase the efficiency of steam boilers to over 90%. EEE is proud to represent BEI and distribute the most innovative economizers available: the  HeatSponge

Experience and Expertise

To sum it up, with over 100 years of combined experience in the boiler business, the EEE team helps clients choose products that produce results while producing steam for applications from hospitals to theme parks to factories to distilleries throughout the state of Florida.
