1. If there is a desuperheater, the water flow of the desuperheater can be increased.
2. Steam spraying to reduce temperature: At the inlet and outlet of the gas storage tank, properly spray to the saturated pressure vessel to reduce the temperature.
3. Discharge ash on the heating surface in front of the overheating vessel: if you discharge ash on the reheater, it can increase the heat absorption of the volatilized heating surface in the furnace, reduce the excess air coefficient at the entrance and exit of the furnace, and then reduce the heat transfer temperature of the heating surface .
4. Reduce excess capacity within the allowable range.
5. Increase the water supply and drainage temperature: When the load does not change, the ignition must be weakened so as not to increase the annual rainfall. The weakening of the ignition will reduce the amount of soot and soot water flow, and reduce the heat absorbed by the heating surface. Reduce the temperature of the overheated pressure vessel.
6. Sinking the ignition management: Moderately reduce the induced draft fan and the fan, so that the flame management in the furnace sinks, so that the amount of smoke and dust entering the heating surface is reduced, the excess air coefficient is reduced, and the temperature is reduced.
