Fouling baking vapours?

Vapours from your ovens may be greasy, sticky or may contain dust which causes heat exchanger blocking.

The business case?

The payback time of waste heat recovery systems must be less than 5 years.

HeatMatrix engineers and manufacturers heat exchangers to recover industrial heat and improve energy efficiency for Bakeries.

Save up to 10% energy on your thermal process

Recover waste heat - that is now lost - from flue gas or baking vapours

Your thermal process has waste heat recovery potential

Production line of baking oat cookies. Biscuits on conveyor belt.

Baking ovens

Up to 20% of heat from baking ovens is lost through the chimney. Heat from hot baking vapours and flue gases can be used to preheat air or water.

Gas boilers in gas boiler room for steam production

Steam boilers

Hot flue gas from steam boilers leaving the chimney still holds more than 10% of energy. This can be recovered and used to preheat combustion air, boiler feed water or cleaning water.

Thermal oil heaters

On thermal oil heaters 15% of energy is lost through the chimney. This can be recovered and used to preheat combustion air or water for cleaning and building heating.

How waste heat recovery systems work

Our waste heat recovery systems for Bakeries

HeatMatrix polymer air preheater

Polymer Air Preheater

Our air preheaters with anti-fouling properties extract heat from flue gases or baking vapours to warm up combustion, convection or circulation air.

HeatMatrix polymer economiser

Polymer Economiser

In our economisers heat from flue gases or baking vapours can be used to heat make-up, boiler feed or CIP water.

HeatMatrix EcoPack

EcoPack

In the EcoPack the exhaust air or flue gas heat is recovered to warm up water. The EcoPack is a complete installed solution for smaller flows. You can directly start saving energy.

FAQ's

Bread or confectionary is baked in (continuous) ovens. The flue gases and baking vapors are sources of waste heat. The waste heat can be recovered and used for combustion or convection air preheating. Alternatively hot water can be generated for usage in (crate) washers, dough preparation or for building heating.

In case of an Economiser, heat recovery will not influence your baking process because the equipment will be installed in a bypass with its own fan. This will ensure that the pressure in the ovens will not be affected. In case of an air preheater, our experts will analyse together with you how air preheating on your oven is feasible.

When you operate your oven for more than 4500 hrs per year, it is very likely that a good business case can be achieved. Our proposal for a turnkey installation will contain an economic assessment of the project.

Flue gas with a temperature of 120 °C can already be a cost efficient source of waste energy. Other variables that play an important role in the business case are the total flue gas flow and running hours of the oven.

HeatMatrix heat recovery systems are easy to clean and maintain. Heat exchanger units can be easily removed for manual cleaning. An in-line cleaning system can be installed that cleans automatically during operation.

Typical payback time of waste heat recovery in industrial bakeries is in the range of 3-5 years. We can help in determining the most attractive combination of waste heat source and heat user to define the best business cases.
