Combustion beam provided with air cooling device and used for lime kiln
The invention provides a combustion beam provided with an air cooling device and used for a lime kiln. The combustion beam comprises a beam body, and a fuel pipeline and a burner which are located in the beam body, wherein an air channel is limited by the beam body; the burner comprises a fuel burner arranged on the fuel pipeline, and a combustion-supporting air pipeline which is arranged on the position, corresponding to a fuel nozzle, of the beam body and is communicated with the air pipeline; a cooling air pipeline is formed in the upper side or the periphery of the beam body and is communicated with the air channel; sprayed air can be used for effectively cooling a top wall of the beam body and preventing high-temperature flame from being in direct contact with the part, particularly the crossed part of a bottom side plate of the top wall of the beam body, so that the ablation effect is reduced; furthermore, the brushing effect on the top wall of the combustion beam by particles clamped in the airflow sprayed out from the burner can be weakened so that the service life of the combustion beam is prolonged; the cooling air pipeline is easy to machine and the total structure size of the combustion beam is not changed; a mounting hole in the combustion beam of an existing kiln body does not need to be adjusted and the combustion beam can be directly mounted on the existing kiln body.
