Embodiment 1
[0027] Such as figure 1 As shown, a heat billing method for heat billing provided by an embodiment of the present invention includes:
[0028] S1, to obtain the supply water temperature of the water supply pipe, the return water temperature of the return water pipe, the mass specific heat capacity of the hot water, the start time of the hot water flowing through the flowmeter, and the end of the hot water flowing through the flowmeter during the heat supply process within a predetermined period of time Comprehensive correction coefficient of time and relative density and specific heat capacity of hot water;
[0029] Wherein, the predetermined time period is set according to the actual situation, and one day may be taken as a time period during specific implementation.
[0030] It can be understood that the flow meter is installed on the return pipe, the hot water flows through the flow meter, and the flow meter can collect multiple parameters of the hot water. Exemplary such...
Embodiment 2
[0039] Such as figure 2 As shown, the embodiment of the present invention provides a multi-level grade thermal energy and thermal cost statistics device based on the return water temperature, including: a multi-gradient integral integrator 1, a first temperature sensor 2, a second temperature sensor 3 and a flow meter 4 , the first temperature sensor is installed on the water supply pipe of the thermal power plant, the second temperature sensor and the flow meter are installed on the return water pipe of the thermal power plant, and the multi-gradient integral integrator is respectively connected with the first temperature sensor, the second Two temperature sensors and flowmeters are connected,
[0040] The first temperature sensor is used to collect the water supply temperature of the water supply pipe during the production of various grades of heat energy by the thermal power plant within a predetermined period of time, and transmit the water supply temperature to the multi...
Embodiment 3
[0048] It can be understood that for high-grade thermal energy, the higher the temperature of the water supply, the higher the input cost of the power plant. Low-grade thermal energy, the lower the temperature of the water supply, the lower the input cost of the power plant. The lower the return water temperature, the lower the steam condensate temperature, the higher the operating efficiency of the boiler, and the higher the recovery rate of low-grade waste heat. Therefore, it is necessary to comprehensively consider the utilization efficiency and cost of heat energy, so the water supply temperature of the water supply pipe and the return water temperature of the return water pipe are the factors that affect the heat price. The lower the return water temperature, for the heat buyer, on the one hand, the more intense the degree of heat exchange, the higher the heat utilization efficiency, the lower the power consumption of the transmission, and the higher the recovery and util...
