8.6.2 Steam accumulator: Steam flow control. In order to prevent a rapid increase in the level inside the steam drums connected to the high-pressure collector due to high steam flow rates, which could lead to the activation of the boiler protection system via an alarm from the steam drum, the steam flow from these drums must be limited to the maximum allowable value during the heating phase of the steam accumulator, until it is connected to the steam network under normal operating conditions. What does this mean? :'(
In order to avoid a rapid increase in the pressure inside any of the steam drums connected to the high-pressure collector due to high steam flow rates, which could lead to the activation of the boiler protection system via an alarm from the steam drum, the steam flow from these steam drums must be limited to the maximum allowable value during the heating phase of the steam accumulator, until the accumulator is connected to the steam network under normal operating conditions. To avoid this issue with the high-pressure collector (heat accumulator?) ) The drum connected to it experiences a rapid rise in liquid level due to the high flow rate of steam supplied, which triggers the LZH alarm protection. The amount of steam supplied from outside the drum needs to be limited to the maximum allowable value during the heat storage heating phase, until normal operating conditions are restored in the steam pipeline system.
Don’t understand. Maximum allowable value during the heat storage heating phase: (
Don’t understand. Maximum allowable value during the heat storage heating phase: (
It should be the maximum temperature and pressure that the regenerator can withstand.
The steam accumulator must be capable of handling the maximum steam flow rate required by the steam piping system; otherwise, a sudden increase in load can cause excessive flashing of the boiler’s water, resulting in a liquid level that drops below the low-level threshold and triggering a boiler alarm.
