Abstract

The invention discloses a low-fuel-air-ratio combustor. The low-fuel-air-ratio combustor comprises a fan. An air inlet is formed in the lower portion of the fan. The air inlet is provided with a baffle. An air outlet of the fan is connected with an air inducing box. The air inducing box comprises a wind inlet, a box body and a wind outlet. The wind inlet is connected with the air outlet. An air inducing cavity is formed in the interior of the box body and in a truncated cone shape. The wind outlet is connected with an air channel. The air channel is connected with a mixing cavity. The mixing cavity is connected with a fuel oil channel. A fuel oil atomizer is arranged at the joint of the fuel oil channel and the mixing cavity. The mixing cavity is connected with a combustion head. According to the low-fuel-air-ratio combustor, the flow rate of air entering the equipment can be increased, and the mixing efficiency of the air and atomized fuel oil is higher and more uniform; the optimal mixing ratio of the fuel and the air can be reached; heating of unnecessary air can be avoided; the combustion efficiency is improved; the production cost is reduced.

Description

technical field [0001] The invention relates to asphalt mixture mixing equipment, in particular to a low air ratio burner. Background technique [0002] The burner is a general term for devices that make fuel and air spray out and combust in a certain way. Burners are classified by type and field of application industrial burner , burner, civil burner, special burner several. [0003] In industrial applications, the fuel utilization rate and combustion efficiency of the burner greatly affect the production cost, and the low fuel utilization rate and combustion rate will also cause great pollution to the environment. The ratio of atomized fuel to air in the use of existing fuel burners is too high, resulting in low combustion rate. Contents of the invention [0004] In view of the above, the object of the present invention is to provide a low air ratio burner to solve the problems existing in the prior art. [0005] The present invention adopts following technical schem...
