At present, the construction of biogas digesters is progressing steadily everywhere, but there are still some problems in the use of biogas digesters, such as the use of biogas lamps. In order to facilitate the normal use of gas by biogas users, the author will introduce the installation and use of biogas lamps and troubleshooting methods as follows.

Install using 1. Before the new biogas lamp is used, the unstrained gauze cover is used for ventilation test firing. If the flame is light blue, it is short and powerful and evenly ejected from the mud hole, and the whirring sound is emitted. The flame is stable and there is no off-fire. Tempering and other phenomena indicate that the lamp has good performance. At this time, the biogas valve can be closed and the shroud can be placed after the mud has cooled.

2. When installing the gauze cover, it should be firmly set in the mud slot, and the asbestos line should be wrapped two times or more, and after the knot is knotted, the excess thread head should be cut off, and then the wrinkles of the yarn cover should be straightened to make it evenly distributed. .

3. When the new yarn cover is first ignited, a higher pressure in front of the stove is required to ensure that there is sufficient amount of methane to burn the yarn cover into a spherical shape. When you turn on the lights, the starting pressure should rise slowly to avoid breaking the gauze.

4. After the biogas lampshade was burned, the man-made fibers were burned and the rest was a white grid of silica. Since thorium dioxide is a toxic white powder, one touch breaks. Therefore, the burned gauze cannot be touched by hand or hit with other objects.

Troubleshooting 1. If there is blue floating fire on the outer layer of the yarn cover, it won't disappear after prolonged use, which means that the air brought into the combustion is insufficient. The lamp pan should be rotated clockwise to gradually increase the air intake.

2. When the biogas lamp is burning, if the yarn cover is not white and red, it is because there is too little biogas or too much air. Rotate the lamp counterclockwise to gradually reduce the amount of air intake. Adjust the lamp to white and the brightness is optimal.

3. The lamp does not emit light. It may be that the nozzle is clogged. Take off the nozzle and use a small sewing needle to pierce the hole. When the lights are bright and dark, it is the reason that there is more water in the gas pipeline or the pipeline is not open. You can open the valve that houses the condensate to eliminate the water in the pipeline or clear the pipeline.

4. Sometimes the combustion is in good condition and the light is not white. This is caused by the poor quality of the yarn cover or the dampness of the collection time. Replace the new yarn cover with good quality.
