[0002] The primary energy consumed by the tunnel kiln, in addition to the energy that must be consumed for heat dissipation of the kiln, product water evaporation, sintering, etc., about 70% of the energy is wasted with the heat loss of the exhaust gas and the heat loss of the product cooling, among these wasted heat ( 20% of the waste heat can be used, 20% cannot be used due to low grade, and about 30% of the waste heat has not been fully utilized; the waste heat can be heated by the waste heat boiler Convert thermal energy into superheated steam, and send the superheated steam generated by collecting waste heat from the waste heat boiler to condensing steam, extraction steam condensing or back pressure turbogenerator for power generation; currently used between the waste heat boiler and the generator set The connection method is conventional steam pipeline erection, but the pipeline of this method is grafted from conventional steam pipeline, which is relatively thick and not suitable for this small-scale power generation, and the pipeline is fixed installation, which is time-consuming and laborious to install and lacks flexibility. Since the moving speed of the generated steam is not stable enough to provide a stable pressure difference, the efficiency of directly using the steam to generate electricity after expanding through the nozzle of the steam turbine is low, which brings certain adverse effects during use. Therefore, we propose a tunnel High temperature steam transportation supply device for kiln waste heat power generation
