Boiler biogas burner is composed of back pressure valve, flame arrester, manual inspection valve, pneumatic valve, burner, exhaust hole, electrical control device, igniter and so on. The integrated device collects the biogas produced in the anaerobic treatment of sewage and transports it to the biogas burner through pipelines. Pressure control to detect the air pressure in the pipe. When the pressure reaches the set value, the pneumatic ignition device will open the pneumatic valve, and the biogas will pass through the flame arrester to the burner, mixed with air for combustion, and discharged into the atmosphere through the exhaust hole. When it is lower than the set value, close the valve and end the combustion.
The main component of biogas, methane, is an ideal gaseous fuel, which will burn when mixed with an appropriate amount of air. The calorific value of pure methane per cubic meter is 34,000 kilojoules, and the calorific value of biogas per cubic meter is about 20,800-23,600 kilojoules. That is, after 1 cubic meter of biogas is completely burned, it can produce the heat equivalent to 0.7 kg of anthracite. Compared with other gases, it has better antiknock performance and is a good clean fuel.
Biogas is a renewable and clean energy that can replace not only traditional biomass energy such as straw and firewood, but also commercial energy such as coal, and its energy efficiency is significantly higher than that of straw, firewood, and coal. Biogas can also generate electricity. The biogas produced by large and medium-sized biogas projects can be used to generate electricity, burn boilers, process food, heat or supply residents. It is a renewable, multi-efficiency and cheap energy source. The use of biogas can alleviate energy shortage and reduce my country's dependence on foreign energy. It has great practical significance for the development of low-carbon environmental protection economy and the establishment of a conservation-oriented society.

Since biogas is a flammable gas, the exhaust hole is at a high position, so the installation of the boiler biogas burner must pay attention to the grounding of the system. The grounding device uses a galvanized angle steel ground electrode (50*50*5, L-2500), and uses a galvanized flat steel (40*4) to connect the ground electrode and the exhaust hole. According to the site conditions, the ground electrode can also be Use underground reinforced concrete or buried metal pipelines (non-flammable and explosive, liquid steam, electrical and other pipelines).
Carry out ignition debugging manually, record the pressure-time, temperature-time curves, and set the parameters of the pressure controller and temperature controller according to the debugging situation. After everything is normal, switch to automatic mode.
Operation method:
Manual operation mode: the rotary switch is placed in the manual position. When the pressure controller shows that the pressure is >1-2Kpa, use the knob switch to open the pneumatic valve, use the button switch to control the ignition, and observe the ignition and combustion process through the observation window on the exhaust hole.
Automatic operation mode: After manual abnormality, the main rotary switch is placed in the normal position. When the air pressure in the pipeline falls below the upper limit of the set value, open the pneumatic valve and start the ignition device at the same time. As the biogas enters the burner, the boiler biogas burner starts to ignite and burn. Automatically half-close the pneumatic valve to end the combustion process.
