What is a low calorific value fuel burner? What are the characteristics of low calorific value burne

Time :2024-01-03 74

A low calorific value fuel burner is a burner that can fully and stably burn fuels with low calorific value (such as blast furnace gas, converter gas, tail gas and various cracked gases, etc.).

This kind of low calorific value burner generally adopts two-stage ignition method. First, a high-energy ignition device is used to directly ignite the combustion-supporting fuel (such as light diesel or flammable gas with a high low calorific value), and then the main fuel is ignited through the combustion-supporting fuel, ensuring the safety and reliability of low-calorific value gas ignition.

Each low calorific value burner is equipped with a flame detection device, which can reflect and process the furnace flame signal in time to ensure the safety of combustion.

This kind of low calorific value burner can realize the proportional adjustment of heat demand and fuel amount, fuel amount and combustion air amount, ensuring the stability of combustion.

The special structural design of the low calorific value burner results in high flame outlet injection speed, strong flame rigidity, and can withstand wind speeds up to 40m/s. Such a design can effectively solve problems such as flame instability, coking, and clogging caused by tar, impurities, liquid hydrocarbons, etc. in the gas.

Low calorific value burners have the advantages of compact structure, stable combustion, large regulation ratio, low noise, good flame spread, complete combustion, and easy control. Its combustion efficiency can reach more than 95%, and it is an energy-saving, economical and environmentally friendly combustion equipment.
