--- Check that the inlet smoke temperature of water-cooling separator should not be more than 1100℃, the refractory material or the metal pressure parts would be burnt if the smoke temperature is too high.
--- Check whether the bed-temperature thermocouple and the related instruments are under normal working state or not.
--- Check the primary air flow of air distributors; make sure that the primary air flow and the secondary air flow should be of normal distribution.
--- Check the percentage of oxygen content in flue gas, and make sure that the oxygen content meter should operate normally.
--- Check the bed pressure of the combustion chamber, prove that the measuring points and the pressure transmission pipeline would not be blocked, and make sure the bed pressure indication would be normal.
--- The operation of the bottom ash disposal system should be monitored, and the bottom ash discharge temperature should be monitored.
--- Check whether the drum water level is normal or not. If necessary, the glass water level sewage should be carried out. And prove that the feedwater control valve operates normally.
--- The sample collection and analysis of the “boiler front material” should be carried out frequently so as to verify the particle size distribution of solid fuels and fuel composition changes.
--- Periodic sampling and laboratory analysis of the feeding water, the boiler water, the saturated steam and the superheated steam should be carried out.
--- The impact of water quality on the steam should be periodically inspected, and the dosing treatment should be done to the boiler water in time.
--- The ash blowing system should put into use periodically. If the outlet temperature of economizer is 16℃ higher than the normal temperature during the boiler normally operating process, ash blowing should be done.
--- Check that whether there is abnormal noise or not, vibration or movement in boiler area or not.
