Characteristics of Blast Furnace Gas Burner, also Known as Blast Furnace Gas Burner

In response to the characteristics of low calorific value, difficult ignition, easy designation, and slow reaction speed of blast furnace gas, the designed and manufactured blast furnace gas burner adopts a three-stage combustion method, which is divided into three stages of combustion. That is, high calorific value fuels (such as natural gas and liquefied gas) are first ignited and used as a normal open flame to ignite a portion of the gas (i.e. auxiliary gas) for stable combustion before igniting the main combustion gas. The burner is equipped with a heat-resistant and stable combustion chamber inside, where gas and air are mixed in the annular gap with swirling blades and sprayed out for combustion, ensuring combustion stability and adequacy.

Basic Principles of Solid Fuel Gasification Reaction

The fixed bed gas generator produces gas by first allowing air to pass through the fuel layer, where carbon and oxygen undergo a cooling reaction to increasing temperature. Subsequently, steam and air are mixed through the fuel layer, and carbon undergoes a mixed reaction of absorption and release of cooling with steam and oxygen to generate producer gas. From the chemical reaction principle of the gas production stage, it is hoped to form conditions conducive to steam decomposition and carbon dioxide reduction reaction. Therefore, it can be considered that increasing the thickness and temperature of the gasification layer is beneficial, and appropriately reducing the steam flow rate is also beneficial. In the chemical reaction between carbon and steam, measures such as increasing the thickness of the gasification layer and reducing the airflow speed can accelerate the reaction speed, increase the content of carbon monoxide, and improve the steam decomposition rate.
