Functional Features of Biogas Booster Fans The biogas boosting and pressure-regulating system is a key design component for both biogas combustion and biogas power generation. It consists of a biogas pressure regulator tank, an explosion-proof booster fan, a control box, pressure gauges, pressure sensors, pipeline fittings, and other related components.
Biogas booster fan Functional features
The biogas booster fan is a specially designed device for the combustion of biogas and biogas power generation. It consists of a biogas pressure regulator tank, an explosion-proof booster fan, a control box, a pressure gauge, a pressure sensor, pipeline fittings, and other components. This device is designed as a booster pump for combustible gases such as natural gas, biogas, alcohol-mixed gases, and straw gas, as well as for harmful and toxic gases. It effectively addresses the issue of insufficient air pressure, ensuring more complete gas combustion and stronger flame intensity. Thanks to its negative-pressure operation, the biogas booster Roots blower is widely used in pipeline transportation systems for various types of biogas and natural gas. It is particularly suitable for situations where biogas or natural gas has low combustion pressure or low pipeline pressure. When the gas supply is insufficient, the booster function of the negative-pressure pump can be utilized to meet the required supply standards and maintain normal pressure levels. The gas booster pump is reliable and leak-free, making it both safe and dependable. Equipped with an automatic control system, it can achieve automated on-off operations within a preset pressure range. Gas fans find applications in boilers, hotels, canteens, firing kilns, residential buildings, and other facilities. They serve as pressure-maintaining devices for gas supply. Biogas suction and supply equipment represents an indispensable and reliable solution for transporting all kinds of harmful gases.
The biogas booster fan employs three sealing methods—packing seal, piston ring seal, and mechanical seal—to ensure the safe conveyance of gases. Among these, the piston ring seal significantly extends the maintenance and replacement cycle of the original packing seal—from 6 months to 3 years. At the same time, while guaranteeing zero leakage of all types of gases, this approach substantially reduces maintenance costs and completely eliminates oil leakage issues found in both double-leaf and triple-leaf fans. The sealing method is thus more effective and cost-efficient.
Biogas projects should be equipped with internal-combustion biogas flares for emergency combustion in cases of excessive gas production or during equipment maintenance. In some industrial projects, biogas generated is treated by burning it through internal-combustion flares to meet stringent emission protection requirements. Landfill gas is actively guided by flares for controlled combustion, achieving both safety, full combustion, and odor removal. Biogas flare ignition design: The flare is designed with a two-stage ignition system, featuring primary and secondary ignition valves. The secondary valve uses a Dongsi solenoid valve, while the primary control valve is an electric butterfly valve. The ignition success rate reaches as high as 99%. Among these, elevated flares are widely used as flare discharge devices in industries such as petroleum, chemical engineering, natural gas, and coal gasification. For flows below 200 square meters, a jet-type combustion method can be adopted without the need for a combustion blower, ensuring quiet and silent flare operation. Flares exceeding 200 square meters are equipped with a combustion cooling fan, which is explosion-proof and low-noise; thus, biogas flares burn without generating any noise pollution. After setting the pressure value for the biogas blower, the pressurizing blower will automatically start or stop based on the pressure within the buffer tank’s biogas pipeline network. When the biogas pipeline network pressure falls below the set value, the pressurizing blower will automatically start. Conversely, when the biogas pipeline network pressure exceeds the set value, the pressurizing blower will automatically stop, thereby maintaining stable pressure inside the tank.
Biogas booster fan Leak-free and safe and reliable. After being equipped with an automatic control system, the device can achieve automated on-off operations within the set pressure range. Frequency conversion can also be used to regulate flow rate and speed. The biogas booster fan is a specially designed process geared toward biogas combustion and biogas power generation. It is primarily used for pressurizing and stabilizing biogas and features safety, convenient transportation and installation, stable pressurization, and automatic control.
The size of the biogas booster fan, as well as the models of the fan and buffer tank, can be customized according to customer requirements. The height and diameter of the biogas inlet and outlet pipes can also be adjusted to meet the specific needs of each project.
