Venturi burner is a device that uses the Venturi effect (fluid acceleration in the contraction section and pressure increase in the expansion section) to achieve efficient mixing and combustion. It is widely used in industries that need precise control of combustion process. The following are its main application fields and characteristics:

1. Industrial Heating and Heat Treatment

-Metallurgical Industry: Used for metal smelting (e.g., aluminum, copper), annealing, forging heating, etc., with excellent high-temperature stability.

-Glass Manufacturing: Used in conjunction with kilns to ensure uniform glass melting and energy efficiency.

-Ceramic Production: Provides stable high temperatures during firing processes to reduce fuel consumption.

2. Chemical and petroleum

-Petrochemical industry: used in cracking furnace, heating furnace, efficient mixing of fuel and air, improve thermal efficiency.

-Chemical reactor: to provide uniform heat source for endothermic reaction (such as ammonia synthesis).

3. Energy and environmental protection

-Waste incineration: combined with secondary combustion technology to reduce the emission of harmful gases.

 -Biomass combustion: suitable for low calorific value fuels, such as straw, wood chips, to facilitate the use of renewable energy.

4. Food processing

-Drying and baking: such as biscuit production line, tobacco drying, temperature control is accurate to avoid contamination.

 -Boiler system: provide efficient combustion scheme for steam boilers in food factories.

5. Other special fields

-Laboratory equipment: Small Venturi burner for scientific combustion experiments.

-Aerospace: Simulate high temperature environment and test the heat resistance of materials.

Technical advantages

-Energy saving and high efficiency: the air and fuel are fully premixed, and the combustion efficiency can reach more than 95%.

-Low pollution: reduce the generation of CO and NOx, and meet environmental standards.

-Strong adaptability: the air-fuel ratio can be adjusted, and it is compatible with natural gas, liquefied gas, diesel and other fuels.

Venturi burners have been widely used in the above industries due to their advantages of simple structure, low investment cost and high combustion efficiency. At the same time, because they do not need an auxiliary burner, they are particularly popular in the occasions where equipment configuration is simplified and energy consumption is reduced.
