The oil burner for waste combustion furnace is a device that injects oil and air into the furnace according to a certain share, a certain speed and a certain mixing method to provide the heat required when the combustion furnace is started / stopped, and the auxiliary heat required when the calorific value of waste is lower than the lower limit of planned calorific value.

   The effect of burner is to start combustion and shut down the furnace to control the reduction rate of furnace temperature; Auxiliary combustion when the calorific value of waste is too low to reach the regular furnace temperature; Drying after new furnace and repairing furnace wall refractory. When the calorific value of waste is lower than 8500kj / kg, the combustion air needs to be heated.

   When the calorific value of waste is lower than 7500kj / kg, auxiliary burners are usually set to meet the requirements of 2S and slag ignition reduction rate when the furnace temperature reaches 850 ℃. When the calorific value of waste is greater than 8500kj / kg, no auxiliary burner can be set, and only temporary combustion burner can be set.

   The oil burner is mainly composed of oil atomizer and air regulator. The fuel oil is atomized into fine oil particles through the atomizer, sprayed into the furnace at a certain atomization angle, and mixed with the air flow with a certain shape velocity distribution sent through the air regulator. At present, compressed air, steam or mechanical centrifugal force effect and other atomization methods are mostly used.
