The system resistance is relatively large when the boiler is running, and the clinker power generation is about 0.4KWh / t, which is relatively low. Therefore, an air duct for the outlet of the kiln boiler is proposed.

A first expansion joint is arranged at the lower end of the first air duct. The diameters of the first air duct, the second air duct, the connecting pipe, the elbow, and the boiler air outlet pipe are 3300-3700mm. The utility model optimizes the first air duct, the second air duct, and the boiler air outlet pipe, expands the diameter, minimizes air intake extrusion, increases the ventilation area, and improves the resistance reduction effect. By utilizing the waste heat of the kiln system as much as possible and increasing the power generation power as much as possible under the same exhaust gas heat conditions, the best comprehensive effect of waste heat utilization efficiency and working medium circulation efficiency is achieved.
