Heat recovery systems for flue gas and baking vapours in Bakeries

Do you need to reduce your energy consumption? Our experts determine your heat recovery opportunities and implement the best heat recovery system in your bakery.

Reduce natural gas usage

Receive a plan for heat recovery

Solve Fouling problems

Your oven, boiler or thermal oil heater is losing up to 20% of its energy through the chimney

What is keeping you from recovering this energy?

Operational priority

You lack time to investigate energy saving possibilities.

Fouling baking vapours

Vapours from your ovens may be greasy, sticky or may contain dust.

Business case

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

We design and deliver heat recovery systems for Bakeries to reduce their carbon footprint

Save up to 10% energy on your thermal process

Recover heat - that is now lost - from flue gas.

Your thermal process has waste heat recovery potential

Select your thermal process to find out how

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.

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.

The way our heat recovery system works

Capture waste heat

Hot baking vapours and flue gases are released to the atmosphere through the chimney. Our heat recovery system captures this heat from baking ovens, steam boilers or thermal oil heaters so it is not lost to the atmosphere.

Preheat air or water

Air, which is heated with the recovered heat, is used for your baking process or boiler combustion. The hot water is used for cleaning processes or heating of buildings. This directly reduces the consumption of fossil fuels.

Our heat recovery systems for Bakeries


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 - Economiser - Small - Vrijstaand - V1.1

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 - vrijstaand - V0.1


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.

Industrial Cookie Bakery

20% gas reduction

The industrial bakery has the ambition to reduce energy consumption. In the production process of cookies many fatty ingredients are used like butter and chocolate. In the oven fouling baking vapours are extracted and currently released to the atmosphere at high temperature. The bakery would like to recover heat from these vapours to reduce overall energy consumption.

Because of the smooth surface of the polymer tubes the HeatMatrix polymer APH has a low tendency to fouling. This aspect in combination with an in-situ cleaning system made it the perfect combination for heat recovery at this bakery. A polymer Air PreHeater was installed and cools down all the baking vapours from the oven.

Circulation air for the oven is preheated from 15 to 103°C, which results in a heat recovery of 143 kW and a reduction of the oven gas consumption of 20%.

Heat Recovery Proposal

We engineer a robust heat recovery solution for your bakery. You receive a proposal with all technical details and an economic assessment with payback time. You have everything for budget approval.


Turnkey Project Delivery

HeatMatrix will design, deliver and install a complete heat recovery system in your bakery, so you don’t have to worry about the implementation.


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.
