Heat recovery # Heat recovery HEAT RECOVERY SYSTEM ## Reducing energy costs and CO2 In a market with ever increasing energy prices and stricter requirements for CO2 emissions, it is important for us to look for and emphasize other ways to recover energy from flue gases, steam and other processes that are generated during combustion. Therefore, we consider heat recovery to be economically advantageous in terms of saving and utilising energy from heat generating processes that would otherwise escape through the flue and chimney directly into the atmosphere. The recovered heat can be used for heating buildings, domestic water or for other purposes in production areas. Or, if there is an option, return the energy to the provider. ## Reduction of fuel consumption The energy loss from flue gas or other thermal process is typically around 15 – 20%. With an exodraft heat recovery system, up to 95% of the heat can be recovered. In other words, there is a potential for a reduction in fuel consumption of up to 12 – 16% and a reduction in CO2 emissions. Exodraft’s solution offers efficient heat recovery with a combination of competitive pricing and an attractive payback period for your investment. ## Customized Calculations for Your Business With our exodraft OptiCalc HR™ simulation software, we can offer you a specific calculation of how much energy your company can save by investing in an exodraft heat recovery system. The exodraft OptiCalc HR™ simulation software also provides information on the reduction of CO2 emissions as a result of the implementation of a heat recovery system. ## Examples of completed projects where the investment pays off From examples of several installations and projects across Europe, we list the industry sectors where the installation pays off in terms of the amount and temperature of the heat removed due to the production processes. We note that previously the heat would have been removed through the ‘stack’ to the atmosphere without further use, with the consequence of increased CO2 emissions. **Sector** **Industry** **Daily Operation** **h** **Days of Operation** **for** **year** **Savings** **kW/​​h** **Flue Temperature** **°C** **Exhaust Gas Flow** **m3/​​h** **CO2** **(kg/​​year)** **Return on Investment** **ROI — years** Zinc Plant24 365 52,5 170 2682 41,433 1,7\* Powder Coater16 280 165 408 3552 63 012 2,9\* Zinc 224 365 62 160 4922 73 830 0,6\* Bakery24 360 190 260 3200 23,941 3\* Launch, paint drying16 250 120 210 2400 9607 1,2\* Bakery 224 360 110 240 2500 37,500 1,2\* \*gas price 0,21 euros / kWh The referenced media source is missing and needs to be re-embedded. 1\) Safe 80 heat recovery unit 2\) Heat generation process, e.g. Boiler, engine, oven, dryer 3\) Stack fan to ensure optimum draft and perfect production results 4\) Hot water storage tank 5\) Circulation pump 6\) 3‑way mixing valve 7\) Integrated bypass 8\) Compact heat exchanger ## Where can heat recovery be used?
