The purposes of continuous and intermittent slag discharge in waste heat boilers
The purpose of regular sewage discharge is to remove the solid deposits accumulated at the bottom of the furnace. The purpose of continuous drainage is to remove water with a high salt content from the surface of the drum water level.
Continuous discharge constitutes a type of surface discharge; it involves releasing boiler water with a high salt concentration from the surface, thereby keeping the salt content of the boiler water within acceptable limits. This helps to reduce boiler water expansion and foaming, as well as the humidity and salt content of the steam, and it can also minimize scaling in the evaporation tubes； Regular sludge discharge is primarily aimed at removing the sediments formed in the water due to the hardness salts generated after chemical addition.
The purpose of continuous drainage is to remove water with a high salt content on the surface of the drum level, as well as oils and foam. The purpose of regular slag discharge is to remove water sludge, scale, and other deposits at the bottom of the furnace.
The purpose of regular blowdown is to remove the solid scale deposited at the bottom of the furnace, reduce the salt concentration in the furnace water, and prevent or slow down the formation of scale on the heating surfaces. The purpose of continuous drainage is to remove water with a high salt content from the surface of the drum water level, reduce the amount of water carried in the steam, and improve the quality of the steam.
Continuous discharge refers to the release of suspended solids from the steam drum； Regular sewage discharge involves the release of sediment from the steam drum.
The regular discharge volume is determined based on the conductivity of the boiler water
Ensure the safe and economical operation of the boiler, and maintain the quality of the steam.
Continuous discharge involves releasing the suspended solids from the steam drum, while periodic discharge involves releasing the settled solids from the steam drum; both methods are intended to ensure the safe operation of the boiler
Well, everyone upstairs explained it very clearly. Thank you
Continuous discharge involves removing boiler water with a high salt content, thereby improving the quality of steam and preventing foaming. This is because there is a critical value for the salt content in the boiler water; exceeding this value leads to excessive water being carried in the steam ； Regular slag discharge is used to remove water sludge, preventing excessive accumulation of such sludge from affecting the water circulation and avoiding tube failures in the water cooling walls.
