APPARATUS FOR CO2 IN GREENHOUSES
Something (sources) is burnt with the aid of some apparatus to CO2 and water. The CO2 will be distributed and give rise to a change of the CO2-concentration.
In more detail the following points will be looked at:
Sources. As such are known: 1° gases CH4, C3H8 and C4H10; 2° fluids paraffin and ethylalcohol; 3° pure CO2 and 4° organic material. The possibilities for use depend on the S-content.
Apparatus. Demands made upon combustion gases by man and plant. Causes of uncomplete combustion, products of uncomplete combustion and damage done on plants. Several types of burners.
Distribution of CO2, by means of a fan or without. The influences of apparatus, glasshouse cover, windspeed, photosynthesis and weather on CO2-concentration.
