Natural gas intelligent heating system and heating method

Abstract

The invention provides a natural gas intelligent heating system. The system involves a temperature measuring sensor, a statistical filter, a storage analyzer, a heat calculator, a heat meter and an automatic combustor, wherein the input end of the statistical filter is connected with the output end of the temperature measuring sensor, the input end of the storage analyzer is connected with the output end of the statistical filter, the input end of the heat calculator is connected with the output end of the storage analyzer, the heat meter and the automatic combustor form a closed-loop controlsystem, and the input end of the closed-loop control system is connected with the output end of the storage analyzer. According to the natural gas intelligent heating system, the heat calculator calculates instantaneous heat consumption of a heating building according to a real-time outdoor air temperature measured by the temperature measuring sensor and data information of the heating building, then the instantaneous heat consumption is directly compared with actual output heat of a gas-fired boiler, the output heat of the gas-fired boiler is adjusted in time according to the comparison result, compared with an existing return water temperature control mode, the adjustment basis is more direct, the adjustment time is shorter, heat adjustment at a certain time period and a certain time point can be completed, adjustment is more accurate, and the conditions of output heat adjustment lag, indoor overheating or no heating cannot occur.

Description

technical field [0001] The invention relates to the field of heating, in particular to a natural gas intelligent heating system. Background technique [0002] With the rapid development of our society, the scale of central heating is getting bigger and bigger, and the society's requirements for the quality of heating are also increasing. Under the circumstances that the current heating mode and energy pattern are constantly changing, the competition in the heating market is becoming increasingly fierce. With the current pressure on environmental protection and the adjustment of pollution and haze reduction measures, a large number of coal-to-gas projects have been implemented in various places, resulting in an increase in the price of natural gas and high heating costs, and my country's energy structure is one of less oil, less gas and more coal. Therefore, only by constantly creating new combustion control methods to reduce gas consumption and waste, thereby reducing heatin...

Problems solved by technology

However, this method cannot directly quantify the amount of heat needed to heat a building at a certain moment and at a certain temperature, especially hot water heating has a large thermal inertia, and the response speed is obviously lagging behind. At the same time, operators are required to frequently adjust the given return water. The temperature and gas volume, the operation task is heavy, and the energy saving effect and heating quality are difficult to achieve the predetermined goals
