A combustion energy-saving safety control system and method

Abstract

The invention relates to an energy-saving and safe burning control system which comprises a burning device with a burner and a flue. An air inlet of the burner is internally provided with a fan, and a fuel gas inlet of the burner is connected with a fuel gas source through a pipe. The air inlet of the burner is connected with an air volume regulator in series. The pipe, connected with the fuel gas source, of the burner is provided with a fuel gas flow regulator. The fan, the air volume regulator and the fuel gas flow regulator are controlled by a terminal controller. The flue is internally provided with a sensor set for detecting the concentration of O2, CO and CH4 in the flue gas and the temperature of the flue gas. The sensor set is connected to the terminal controller in a feedback mode. The terminal controller is connected to a cloud data processing platform of a monitoring center through network. The invention further provides an energy-saving and safe burning control method. By means of the energy-saving and safe burning control device and method, the problem that an existing burning device cannot achieve accurate control is solved, and energy-saving and safe operation of the burning system is guaranteed.

Description

technical field [0001] The invention relates to combustion system technology, in particular to a combustion energy-saving safety control system and method. Background technique [0002] At present, the combustion debugging of gas-fired boilers is usually carried out by the staff through visual observation. The combustion status is completely determined by the experience of the staff. They often use the color and shape of the flame to debug the combustion. This kind of subjective control often fails. to the ideal combustion conditions. Although some units also detect and analyze the flue gas composition through flue gas analyzers and other equipment, and regularly adjust the air-fuel ratio of the burner accordingly, the combustion conditions are always changing in real time. For example, natural gas pressure fluctuations will affect the flow of natural gas in the same proportion. , so that the combustion air-fuel ratio is actually out of control during most of the running ti...
