As we all know, the Venturi combustion nozzle, also known as the self-priming burner, is a combustion device that uses the Venturi effect. The characteristics of wenturi combustion nozzle include simple structure, low investment cost and no need for combustion fan. They usually use natural gas or LPG as a fuel, and are widely used in modern kilns, especially in shuttle kilns. The nozzle works based on the momentum exchange process in Venturis, where high-speed gas drives the surrounding air into the nozzle, realizing the mixture of gas and air. Due to its special structure, venturi combustion nozzle can achieve effective combustion in the absence of external fan, and due to the fast combustion speed, hydrocarbons are too late to decompose, so there are no or few free carbon particles in the flame, showing the characteristics of flameless combustion. Let's talk about its advantages and disadvantages.

The advantages of the Venturi burner include:

High combustion efficiency: The Venturi burner can provide a stable combustion environment and ensure product quality and yield.

Simple operation: wenturi burning mouth structure is simple, convenient installation, flexible operation, reduce the labor intensity of workers.

Energy saving and environmental protection: Venturi burner has high combustion efficiency, high thermal efficiency, and can effectively reduce energy consumption and exhaust emissions, and meet the requirements of environmental protection.

Small air excess coefficient: can make the gas completely burned, low pollutant emissions.

Gas and air premixing: high combustion temperature.

Modular design: easy to replace and repair.

The nozzle material is excellent: the nozzle is made of high temperature stainless steel or ceramic material, with long service life.

Simple pipeline design: do not need tedious pipeline valve design.

The disadvantages of the Venturi burner include:

Single size: limits its application in specific situations.

High gas pressure requirements: increased in the use of restrictions.

Limited air and gas preheating: it may affect the combustion efficiency.

Small burner load ratio: it limits its performance at high load conditions.

Large fluctuation of the furnace pressure: poor stability.

Small power: it may not be suitable for industrial applications that require large amounts of heat.

In conclusion, Venturi burner has many advantages, but also some limitations. Users should consider their own needs and the above advantages and disadvantages to choose products.
