When the boiler’s heat load fluctuates frequently and frequently, measures should be taken to balance the load so as to achieve effective adjustment. The system of multiple boilers should be equipped with centralized control devices to ensure the boiler running balance and in economic operation. The selection of boiler medium parameters should meet the requirements, and the rated outlet pressure and temperature of the boiler should not be much different from the applied pressure and temperature.
The boiler auxiliary equipment should be matched with the boiler to meet the requirements of efficient operation of the boiler and its system. The boiler feed water pump should adopt the variable speed device and use the variable speed unit to operate the unit. The selection of the burner parameters should be calculated according to the rated output of the boiler, the variety of fuel, the mode of combustion and the resistance of the smoke air system, and it is modified according to the air oxygen content, the temperature and density of the smoke and the local pressure. The heat discharged from the waste water should be rationally utilized. It is advisable to set up a continuous sewage discharging and expanding container and a sewage discharge heat exchanger according to the total amount of continuous sewage discharged from the boiler room. For a steam boiler room with a total capacity greater than or equal to 10t/h, a discharge container or a drain heat exchanger should be set up to recover the heat of the sewage and reduce the loss of sewage. The boiler and its system should eliminate running, risking, dripping and leakage, making full use of the heat of condensate, two steam and continuous drainage, and taking measures. As far as possible, the recovery and utilization rate of condensable water can be raised; the cooling water of the pump bearings and the water for ash removal and ash removal should be circulated as far as possible.
