(1) two blowers are stopped.
(2) Two induced draft fans are stopped.
(3) Two air preheaters are stopped.
(4) Two primary fans are stopped.
(5) The furnace pressure is extremely high.
(6) The furnace pressure is extremely low.
(7) The drum water level is extremely high.
(8) The steam drum water level is extremely low.
(9) All three water circulating pumps are stopped.
(10) the total wind m of the boiler is lower than 30%fMCR.
