According to the local conditions, the boiler use unit formulates the relationship between the boiler outlet water temperature and the outdoor air temperature. In the operation, according to the corresponding relationship between the specified outlet water temperature and the outdoor air temperature, the combustion amount is adjusted in time, and the water supply temperature of the network management system is required to be different from the specified temperature. 120 ° C. The change of water supply temperature should be carried out step by step, and the water temperature increase or decrease should not exceed 20 °C.
The outlet temperature of the hot water boiler should be lower than the corresponding saturation temperature at the operating pressure (ie, the vaporization temperature of the boiler water) below 20 °C.
The outlet temperature of the parallel running hot water boiler should also be controlled at any time. When the heating load is not large, the water temperature of the boiler with a higher outlet temperature is lowered by the method of weakening the combustion; when the heating load is large, the method of opening the boiler outlet valve with a large outlet water temperature is adopted for adjustment.
