The Venturi gas mixer is a device used for mixing gas and air, widely applied in combustion systems, industrial heating, gas boilers, and other fields. Its core principle involves utilizing the Venturi effect from fluid dynamics, where the negative pressure generated by high-speed airflow draws in another gas to achieve uniform mixing. Below is a detailed introduction to the Venturi gas mixer:

main features

Automatic adjustment of the mixing ratio: through the zero pressure valve or intelligent control system, ensure that the ratio of gas to air is stable, even if the air pressure fluctuates, it can still maintain safe combustion.

No additional pressurization: gas does not need additional pressurization, only the butterfly valve needs to be adjusted to adjust the heat output.

Safe and reliable: there are oxygen analyzer, calorific value meter and other safety interlock system, when the mixing ratio is abnormal, the gas supply can be automatically cut off.

Multi-tube parallel design: suitable for large flow demand, can automatically start and stop a single tube to match the gas consumption.

Main applications

Industrial combustion system: such as boiler, kiln, drying equipment, etc.

Gas mixing station: used for air mixing of natural gas and liquefied gas to improve combustion efficiency.

Environmental protection energy system: such as biomass gasification, biogas utilization, etc.

Installation and maintenance precautions

Installation environment: good ventilation, away from flammable and explosive items, and in accordance with explosion-proof electrical specifications.

Pipeline requirements: The shut-off valve shall not be installed on the outlet pipe of the mixture to avoid the risk of backfire.

Periodic inspection: oxygen content, gas pressure should be monitored, and air filter should be cleaned regularly.
