High speed burner is different from high speed temperature regulating burner, they are both related and different, the following is a detailed introduction for you:

High-speed temperature-regulating burners are a type of high-speed burner and possess some basic characteristics of high-speed burners. The fundamental feature of high-speed burners is that the fuel reaches near-complete combustion in the first half of the combustion chamber or channel. Since the combustion chamber is sealed and maintains sufficiently high pressure, the high-temperature combustion products are ejected at a speed of 100 to 300 meters per second, enhancing convective heat transfer within the furnace. High-speed temperature-regulating burners can also achieve high-speed ejection of combustion gases, with the gas outlet velocity reaching over 100 meters per second.

Usage

High-speed burner: It is widely used in industrial furnaces with strict requirements on furnace temperature uniformity, such as large heat treatment furnaces and forging heating furnaces. Its main function is to realize uniform and rapid heating of furnace temperature by promoting the strong circulation of furnace gas through high-speed gas flow.

High speed temperature control burner: usually used in heat treatment and drying furnace, the temperature of combustion gas can be adjusted according to process requirements to meet different heating needs.

Structure and working principle

High-speed burner: After the fuel is basically completely burned in the combustion chamber, the high-temperature combustion products are ejected at high speed by the pressure of the combustion chamber. Some high-speed burners realize the flue gas temperature regulation by supplying adjustable secondary air at the outlet of the combustion chamber or the rear half of the combustion tunnel.

High speed temperature control burner: most of them have secondary air, which reduces the temperature of the combustion gas at the outlet to close to the heating temperature of the workpiece by mixing in secondary air. The temperature regulation range of the combustion gas is large.

Performance parameters

Excess air coefficient: the high-speed non-temperature regulating burner used for rapid heating in the high-speed burner does not supply secondary air, and the excess air coefficient varies little; while most of the high-speed temperature regulating burner has secondary air, the excess air coefficient changes greatly, usually between 1 and 50.

Temperature regulation range of combustion gas: the temperature regulation range of combustion gas is small for high-speed non-temperature regulating burner; the temperature regulation range of combustion gas is large for high-speed temperature regulating burner, which can meet different process temperature requirements.

sum up

The characteristics of high-speed burners include high-speed non-adjustable nozzles for rapid heating and high-speed adjustable burners for heat treatment and drying furnaces. The feature of high-speed adjustable burners is that the combustion gas outlet speed can reach over 100 meters per second. By adding secondary air, the temperature of the combustion gas at the outlet can be reduced to near the heating temperature of the workpiece. Therefore, using high-speed adjustable burners can enhance convective heat transfer.
