Heating of the waste heat boiler
Thread Content
The unit has been put into operation. When the waste heat boiler is heated, is the steam generated by it released on-site, or is it retained in the boiler until the steam pressure reaches the level required for delivery? Everyone, tell us how you did it – extra points!
If the furnace needs to be boiled, release the steam first. If there is no need to heat the furnace, reducing the steam pressure to the normal operating level will allow connection to the grid.
The starting pressure does not reach the level required for grid connection, so it is necessary to vent
Can it be kept inside the boiler so that the pressure can increase gradually, without the need to release it?
It is not conducive to raising the temperature. The boiler operation procedures are clearly written
Why is it not conducive to raising the temperature? Can you tell me?
It should still be based on the furnace heating temperature, following the furnace heating curve.
Before the remaining heat in the boiler stabilizes, vent it on-site first; however, the steam drum needs to be kept under pressure as its temperature rises, otherwise the temperature inside the waste heat boiler will not increase
