CO2 Combustion Generators
The CO2 generator
has long been
a fixture
of commercial greenhouse growers. Unlike the injection system, the generator works by constantly creating CO2, instead of releasing enough to treat an entire room at one time.
The generator is often used in greenhouses because the structures are drafty and the CO2 enhancement would be soon lost if the release was intermittent. The process used by commercial CO2 generators is quite simple. A clean burning gas such as propane or natural gas is burned through a burner like is found in a stove or furnace. Each pound of gas burned yields about 3 pounds of CO2, or about 25 cubic feet.
The generation principal works on all levels. Large commercial generators are used in greenhouses and large area growth chambers. A simple and small alcohol lamp can be used in a closet growth chamber to provide CO2 enhancement, although I cannot recommend a flame in a room with combustible materials.
