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.
You lack time to investigate energy saving possibilities.
Vapours from your ovens may be greasy, sticky or may contain dust which causes heat exchanger blocking.
The payback time of waste heat recovery systems must be less than 5 years.
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.
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.
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.
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.
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 air preheaters with anti-fouling properties extract heat from flue gases or baking vapours to warm up combustion, convection or circulation air.
In our economisers heat from flue gases or baking vapours can be used to heat make-up, boiler feed or CIP water.
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%.
Our heat recovery experts determine the most interesting opportunities for waste heat recovery for your bakery. You receive an overview of options.
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.
HeatMatrix will design, deliver and install a complete heat recovery system in your bakery, so you don’t have to worry about the implementation.
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.
