in steam generator comprises economizer, evapora-tor, and superheater. Saturated steam from the boiler drum is fed to the superheater to further heat it to the steam turbine inlet temperature of 510 C at a pres-sure of 86.2bar. With regard to the flue gas
Get price2016/7/30 · Steam is first heated in a steam generation system (for example, in boilers or waste heat recovery systems), where it reaches a high temperature, around 400 C to 600 C. The first valve that the steam encounters as it travels from the steam generation system to the steam turbine is the main stop valve (main trip or shutdown valve), which is either fully opened or fully …
Get priceAs can be seen, the steam and condensate system represents a continuous loop. Once the condensate reaches the feedtank, it becomes available to the boiler for recycling. Energy monitoring. In today's energy conscious environment, it is common for customers to monitor the energy consumption of their plant.

Get priceIn some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler …
