Installation of spray nozzles at the condenser throat
Thread Content
The small unit has a capacity of 20 MW and 5,500 R. Without condenser throat spraying, but now the management wants to make modifications by adding throat spraying, which can improve the vacuum level. I would like to ask the experienced experts what impact adding a spray system can have on vacuum, and what flow rate is required to achieve a more significant effect The condensate pump has a rated capacity of 95 T/H; currently, the amount of condensate produced is around 88 T/H. There isn’t much space left – will this approach be effective?
We usually use turbines associated with condensers; in such systems, the amount of condensate produced is roughly proportional to the amount of steam used. To increase the vacuum level, it is necessary to increase the thermal load, that is, the amount of cooling energy applied. Installing spray nozzles can be effective, but the heat exchange area also plays a role – if this area is too small, the effect of installing spray nozzles will be limited. In such cases, it might be advisable to divert some of the steam and connect it to a smaller heat exchange device, thereby increasing the effective heat exchange area.
What does 5500 R mean by the poster?
