Determination of boiler steam blowdown flow rate
Thread Content
How is the flow rate for steam purging in a boiler determined? Can the electric feed water pump supplied as part of the system meet the water supply requirements? Is it related to the boiler’s rated parameters? I would appreciate your guidance. Thank you!
According to the specifications of power construction industries, the steam flow rate required for blowing pipes should be 60-70% of the rated evaporation capacity. Additionally, the normal water supply flow rate is only 30% of the capacity, and a pressure-reduction blowing method is used. Purpose of the blowing pipe: The blowing pipe uses steam under certain pressure to purge the superheaters and main steam pipes, releasing this steam into the atmosphere. Through this steam purging process, impurities such as rust, dust, and oil in the pipes are removed, thereby preventing these impurities from posing a threat to the safe operation of the boiler and turbine.
