Abstract


High temperature corrosion is the power plant boiler water wall face of a more serious problem. Taking dagang power plant 2 x 328.5 MW tangential burning coal boiler as an example, carries on the experimental study. In the prototype boiler on the basis of 1:20 scale test rig is established. Preliminary design scheme for the original furnace, in the cold state aerodynamic field modeling experiment platform, a wind concentric methods of combustion in furnace cold experimental research. Using IFA 300 thermostat hot-line anemometer (membrane), combined with ribbon method and particle tracer technique, under the arrangement of burners for different furnace air dynamic field measurements and observations, and comparing with numerical simulation results, we grasp the burner area airflow characteristic, proposed the thorough settlement of power plant boiler water wall high temperature corrosion problems reasonable Suggestions, to have certain guiding significance to the engineering practice.
