Waste 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% energy via the stack or chimney
What is keeping you from recovering this waste heat?
Operational priorities?
You lack time to investigate energy saving possibilities.
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.

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.
How waste heat recovery systems work
Our waste 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.
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 Air Preheater 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
How to save energy in a Bakery plant?
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.
Will waste 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 waste 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 waste heat recovery 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 waste 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.
Payback time of waste heat recovery in a Bakery plant?
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.
