Abstract

The drainage waste heat utilization system of the power station boiler comprises a water collecting tank and multiple sets of water outlet and return devices, each water outlet and return device comprises a water outlet mechanism and a water return mechanism, the water outlet mechanism comprises a water outlet mechanism arranged on a drainage tank, and the water return mechanism comprises a water inlet pipe connected to a water cooling wall. The water outlet mechanism and the water collecting tank are used for inputting drained water into the water inlet pipe of the other water outlet and return device. The method has the effect of improving the drainage waste heat utilization effect.

Description

technical field [0001] The present application relates to the field of waste heat utilization, in particular to a drainage waste heat utilization system for power plant boilers. Background technique [0002] Power plant boilers are mainly divided into pulverized coal boilers and circulating fluidized bed boilers. The circulating fluidized bed boilers use the clean coal combustion technology with the highest degree of industrialization. [0003] The boiler includes a furnace, a cold water wall installed in the furnace, a steam drum connected to the cold water wall, a downcomer connecting the steam drum and the cold water wall, and a steam pipe connected to the steam drum. The water in the tank is heated so that the water in the cold water wall forms a steam-water mixture and enters the steam drum. After the steam-water mixture is separated by the steam drum, the water returns to the cold water wall through the downcomer, and the water vapor is transported to the steam turbine...
