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

FAQ's
Will heat recovery influence my baking process?
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.
My ovens do not run continuously. Is a heat recovery system still an interesting investment?
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.
What is the minimum temperature required for the system to work cost efficient?
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.
How is fouling managed in the HeatMatrix heat recovery systems?
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.
