Embodiment Construction
[0030] The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0031] A method for monitoring the safety impact of water-cooled wall tube weld bumps on the tube wall, comprising the following steps:
[0032] 1. Continuously collect the inlet and outlet header pressure of the water wall, the wall temperature of the water wall, the temperature of the furnace combustion center, the load of the unit and the flow rate of the feed water to obtain the collected data under each load condition, and check the validity of the collected data;
[0033] 2. Carry out three-dimensional flow and heat transfer calculations for water-cooled wall tube panels under each load condition;
[0034] In the calculation process of each load condition, a water-cooled wall tube in the water-cooled wall tube panel is taken as an object, and the shape of the weld bead in the water-cooled...
