Questions regarding the lock hopper circulation pump and the lock hopper
Thread Content
Everyone, I would like to ask: if the size of the lock hopper increases, does the flow rate of the pump used for circulating water in the lock hopper also need to increase? Still the same?
Personally, I don’t think it’s necessary to make it bigger! If the lock hopper is enlarged, the slag skimmer must also be enlarged! Increase investment in equipment!
Reply 1# wonchin: An increase in the size of the lock hopper indicates an increase in the amount of slag, as well as a higher ash content in the raw coal used. It is inevitable that the circulation rate increases under such conditions; the extent of this increase depends on the actual operating conditions. The pump outlet valve is usually kept fully open to ensure smooth slag discharge. In general, such situations should be designed by a design institute, as they are experts after all.
1. There is no need to increase the lock chamber. 2. Even if the volume is increased, there is no need to increase the circulating water, as the vaporization furnace remains unchanged
