Carbon dioxide (CO2) is an important aspect to improve crop production
In crop production, it is important to ensure that there is enough carbon dioxide (CO2) in the air since that is essential for photosynthesis and hence for plant growth. CO2 is generated whenever the boiler is in operation since it is contained in the flue gases.
The waste heat can also be stored, depending on the requirements of the greenhouse facility. CO2 is required for plant growth during the day, whereas at night the heat is needed to maintain a stable growing climate. The excess heat produced during the day is stored in a heat storage tank so that it can be used at night.
