The combustion efficiency of industrial burners plays a vital role in its industry, but the combustion efficiency of industrial burners is affected by a variety of factors, which we will explain in the following aspects:

Combustion temperature: Combustion temperature is one of the key factors affecting the combustion efficiency of incinerator. According to the principle of chemical reaction, the combustion reaction rate is positively correlated with the temperature, that is, the higher the temperature, the faster the combustion reaction rate and the higher the combustion efficiency 1.

Fuel Properties: The calorific value, volatile matter, moisture content, and ash content of fuel all affect combustion efficiency. For example, fuels with high calorific value can release more energy during combustion, improving efficiency; fuels with high volatile matter content are easier to ignite during combustion, which also enhances efficiency; fuels with high moisture content require more heat to evaporate water during combustion, thereby reducing efficiency.

Airflow Angle: The influence of airflow Angle on combustion efficiency in industrial burners is mainly reflected in mixing speed and combustion completeness.In the burner operation, natural gas and air flow at a certain angle. The greater the angle between the two, the faster they mix, leading to more complete combustion. If the flow rates of natural gas and air are very slow and they move in parallel, their mutual diffusion is much slower, resulting in insufficient combustion. The path of mixing will be longer, and the visible flame will also be longer. This is why many users aim for a long flame but not high temperature during use.

Air excess rate: Air excess rate refers to the ratio of the actual air supply to the theoretical air required. The appropriate air excess rate can ensure that the fuel is fully burned, thus improving combustion efficiency.

Flow characteristics in the furnace: Flow characteristics in the furnace include the speed, direction and distribution of gas flow. Good flow characteristics help fuel and air mix well, thus improving combustion efficiency.

Burner design: The design of the burner directly affects the mixture of fuel and air, which in turn affects the combustion efficiency. For example, the mixing conditions can be improved by changing the gas flow rate and reducing the diameter of the gas flow to improve the combustion efficiency.

Exhaust loss: Exhaust loss refers to the percentage of heat carried away by the flue gas to the input heat. Exhaust loss can be reduced by reducing the amount of flue gas and reducing the temperature of the flue gas, so as to improve the combustion efficiency.

Flue gas purification technology: Flue gas purification technology can reduce the emission of harmful substances, but also affect the combustion efficiency. For example, the use of low nitrogen oxide combustion technology can reduce the emission of nitrogen oxide while improving the combustion efficiency.

To sum up, the combustion efficiency of industrial burners is affected by a variety of factors. In order to improve the combustion efficiency, it is necessary to comprehensively consider the above factors and take corresponding optimization measures.
