Abstract

The invention discloses a gas use peak adjusting method for a heating system. The heating system comprises a heating loop, a heat storage loop and a heat release loop; a gas boiler, a second electrictwo-way valve, a heat storage tank, a heat storage circulating pump and a first electric two-way valve are arranged on the heat storage loop in sequence according to a fluid circulating direction; a heat storage tank, a heat storage circulating pump, a third electric two-way valve and a heat exchanger are arranged on the heat release loop in sequence according to a fluid circulating direction; a primary side of the heat exchanger is connected to the heat release loop; and a secondary side of the heat exchanger is connected with the gas boiler in parallel. The method comprises the following steps: in the gas use valley period, the heat storage tank stores redundant heat generated by the gas boiler; and in the gas use peak period, the heat storage tank releases the heat to the heat exchanger, and the heat exchanger and the gas boiler provide the heat to a heat exchange unit together to reduce the gas use demands of the gas boiler. The gas use demands in the gas use peak period of naturalgas in cities can be greatly reduced.

Description

technical field [0001] The invention relates to a gas peak-shaving method, in particular to a gas-shaving peak-shaving method for a heating system. Background technique [0002] With the implementation of the "coal-to-gas" policy, the supply of natural gas in major cities in winter has entered a serious shortage, seriously affecting the use of heating systems and kitchen gas systems. [0003] The hourly load of the heating system is affected by the use function and load characteristics of the heating users, and it shows an operation rule of high during the day (7:00-21:00) and low at night (21:00-7:00) during the day; in actual operation, The demand for natural gas in the heating system is linearly related to the heating load, that is, the demand for natural gas also shows an operating law that is large during the day and small at night. [0004] The demand of the kitchen gas system is affected by the meal time of urban residents, three meals a day in the morning (7:00-9:00...
