Chapter Nine: The Combustion Fan



The amount of air, and thus oxygen, reaching the flame is one of the factors you can vary to affect how the fire burns. Grain stove operators usually want to get more air to the fire so they can get the fire going strong to create enough heat to keep the grain-burning process going. In fact, we have found that the grain burning process requires so much air, that when the dip switches are set to recommended grain-burning settings (3,4,7 and 8 are turned on), the combustion fan is constantly on high. Therefore, after the dip switches have been set, there is little you can do to increase the amount of air reaching the flame. If you are trying to burn extremely tough grain, the only other thing you can do to increase the air is to install a double paddle combustion fan (part #3-20-50221 approximately $11.60 ). However, most grain stove operators in Western Canada should not need the double paddled fan.
