Boiler startup capacity
Thread Content
May I ask, what capacity is generally required for a start-up boiler for a 600,000-unit unit?
A boiler with a capacity of 30 T/H will be sufficient to meet the requirements.
How is 30T/H calculated? How much is needed for the deaerator? How much shaft seal is needed? Are there any other places that need to be used besides these two?
0.7MW is equivalent to 1T/H. 600M/0.7M = 858T/H. Is this calculation clear? Hope it helps
The basic specifications of the southern power plant are 35 T/h, 1.27 MPa, and 350 degrees. It is related to the requirements for auxiliary steam parameters; power plants in the north may also need to take into account factors related to winter heating. However, since it is a boiler meant for startup, 35t should be sufficient. The 1000MW unit has a capacity of 50T/h.
The deaerator requires about 27 tons, the shaft seals need 5 tons, and there is also steam for heating oil tanks and steam for purging air preheaters.
Due to environmental influences, the south and the north are different.
A 600,000-kilowatt power unit refers to a generator set with a capacity of 600,000 kilowatts; the boiler associated with it has a capacity of 2,000 steam tons. The steam used for pneumatic purposes is mainly applied in areas such as deaerators, superheaters, reheaters, and shaft seals； It requires a superheated steam boiler with a capacity of 50 steam tons, at 2.5 MPa and 350°C
How many tons exactly? Is the ambient temperature in this power plant relatively high? Average ambient temperature: 30 degrees Celsius
The specific figures depend on the decision made by the power plant’s design department
