The stirring vane of bottom and the motor composition being located at outside blowdown drum.
Preferably, the pipeline streamwise that connects between described top steam drain and water-blaster has downward gradient, and this inclines
Oblique angle is preferably 4 °～6 °.
Injection boiler described in the utility model uses fluidized-bed combustion boiler, coal-powder boiler, grate furnace, gas fired-boiler or oil burning boiler.
This utility model has the following advantages and beneficial effect compared with conventional continuous blowdown system of boiler: 1. common platoon can only be by life
Become steam discharging, and this utility model can by Steam Recovery heating boiler feed water, economize on water, energy-saving effect obvious；2. can
Reclaiming the salt such as potassium, sodium salt, precious metal rare for separation and Extraction further from potassium, sodium salt provides guarantee reliably,
Economic benefits；3. this utility model simple in construction, easy to implement, can join with newly-built or old uphole steam generator
Set uses, and injection boiler can be fluidized-bed combustion boiler, coal-powder boiler, grate furnace, gas fired-boiler or oil burning boiler；4. can be complete
Realizing Electronic control, labor strength is low.
