Biogas Stove Design
This biogas stove design page contains designs developed explicitly for low-pressure gas burners from digesters or storage holders containing biogas. The significant advantage of a gas burner is that the heat can be directed to where it is needed. In a good design the stove avoids problems that can occur when burning gas, especially biogas. For example, biogas burns over a narrow range of mixtures containing 9 to 17 per cent of air. If the burning flame is fed too much gas, the burn will be poor and incomplete. It can give off poisonous carbon monoxide and contain sooty carcinogenic particles.
A good biogas stove design aims to reduce unburned methane and soot from incomplete combustion. For this reason, a stove should burn on the lean side. A small amount of air is mixed to avoid the flame becoming rich. In a good biogas stove design, the air is mixed with the gas before it is burned. This ensures the correct air-gas mix is obtained. Reading through documents below, you will see other problems such as flame lift, pressure drop and the burner manifold issues.
A good design will have significant health advantages compared to traditional cooking practices over an open fire. Good design means smokeless cooking, reducing the number of eye infections and respiratory problems among women and children. Small children around a well designed stove means greater safety and less likely to receive burns when cooking is underway.
