In the field of furnaces and kilns, the most popular burners are high-speed burners and flat-flame burners. High-speed burners are generally installed on the side wall or end wall of the furnace, and flat-flame burners are generally installed on the top of the furnace, and can also be installed on the side wall according to the needs of use. Depending on the fuel used, burners are divided into gas burners and fuel burners. Users can choose to use it according to their needs.

High-speed burners are widely used in various furnaces in various industries. The high-speed burner is a > 100m/s high-speed flame gas emitted from the burner to coil the gas in the furnace to form a strong circulation, which can improve the convective heat transfer and temperature uniformity in the furnace. The temperature of the outlet combustion flame gas is reduced to close to the heating temperature of the workpiece by adding secondary air, and the mass flow rate of the flame gas in the low temperature section of the furnace increases after the secondary air is added, which can increase the convective heat transfer coefficient of the air flow to the workpiece, thereby improving the heating quality of the workpiece. When the high-speed burner is equipped with two-position control, the fuel and combustion air can be adjusted according to the actual measured temperature in the furnace and the temperature required by the heating process, so that the temperature of the workpiece can be automatically adjusted according to the requirements of the required heating process.

Flat flame burner - the air passes through the tangential cyclone, forming a strong rotation, the gas radial spray at the flared diffusion port is mixed with the air flow, under the action of centrifugal force, the air flow is evenly diffused around the inner edge of the furnace wall, and the reflux area is formed in the axial center of the burner, when the reflux medium is refluxed to the outlet of the rotary air flow, it is rolled into the main rotating flow strand by the air flow and becomes a part of it, and the reflux medium with the flame gas in the furnace can play a role in stabilizing the flame ignition, and can also promote the flow of the flow strand attached to the wall. The result is a flattened disc flame. The main advantages of using a flat flame burner are: uniform furnace temperature, fast heating speed, good ignition performance, and low fuel consumption.
