Corrosion and fouling problems limit heat recovery in breweries, distilleries and soft drinks plants. We design and deliver a robust heat recovery system for your plant so you can recover more heat.
It is complex to determine the best way to lower your energy consumption.
Your flue gas is potentially corrosive or fouling.
Your flue gas is corrosive when you burn biogas, oil or coal. Recovery of additional heat below the acid dew point is however possible. The heat is used to preheat combustion air or water
When hot flue gas leaves the stack, it still contains a significant amount of energy. Our heat recovery system captures this heat from steam- or hot water boilers, or CHP systems.
Combustion air, boiler feed water, make-up water, CIP water or building heating are warmed up with the captured waste heat. This directly reduces the consumption of fossil fuels.
Warm up combustion air by extracting heat from flue gas. The air preheater is corrosion resistant, easy to maintain and to clean.
Within the Together Towards ZERO program, Carlsberg strives to make their breweries more sustainable. One of the steps taken in their Ukraine brewery is using a biogas fired steam boiler.
Due to the usage of biogas, high concentrations of sulphur elements can be found in the flue gas. If the flue gas is cooled down, these sulphur components condense and form sulphuric acid which is very corrosive. To prevent this from happening, Carlsberg operated their system such that the flue gas was at a high temperature (>140 °C) leaving the stack. Additional heat present in the flue gas was not used.
HeatMatrix installed a polymer air preheater which allowed Carlsberg to cool to temperatures below the acid dew point and achieve additional heat recovery on their steam boiler. There are no corrosion issues because of the corrosion resistance of the polymer used in the HeatMatrix APH. Based on the success in Ukraine, Carlsberg Serbia introduced the same solutiton on their biogas fired boiler.
HeatMatrix will design, deliver and, upon request, install a complete heat recovery system on your site, so you don’t have to worry about the implementation.
The thermal efficiency is the precentage of the combustion energy (Lower Heating Value) that is effectively converted to steam. The remainder of the heat is lost via the stack. The efficiency of a steam boiler lies in the range of 85 - 95%. By installing an economiser or an air preheater, the loss of heat in the flue gas is reduced and thereby the boiler efficiency is improved and CO2 emissions are reduced.
Making your boiler more efficient reduces its fuel consumption and therefor lowers fuel costs. Clients have improved their efficiency by 5 to 10% and achieved payback times on the project investment in the range of 3 to 5 years.
The steam boiler(s) and Wort boiler (in case of a brewery) are sources of waste heat. Improving energy efficiency of the beverage plant process can be achieved by recovering this waste heat. The Wort boiling step is one of the major energy consumers in the brewing process. Recovered energy can be directly integrated in the process or used to generate hot process/washing water.
Payback times for waste heat recovery in breweries or beverage plants will be in the range of 3-5 years. A heat recovery scan provides the best starting point to determine the best integration of waste heat into the plant.
