Problems solved by technology
[0003] At present, most of the existing boiler fuel addition and ventilation control are done manually based on experience. On the one hand, it is not only inefficient and wastes manpower, but also the accuracy of adjustment is also very poor, often resulting in insufficient fuel or air, and the combustion efficiency of the boiler. relatively low
In addition, it is dangerous to do it manually

The invention provides an intelligent boiler system for detecting and controlling tail gas emission on line. The intelligent boiler system comprises a CO / CO2 content setting and acquiring apparatus, a CO / CO2 content measuring apparatus, a fan regulating valve, a fan, a fuel flow control regulating device and a fuel spray gun, wherein one end of the fuel spray gun is connected to a boiler; the other end of the fuel spray gun is connected to the fuel flow control regulating device; the control regulating device is in data connection to a central controller; one end of the fan is connected to the boiler, and the other end of the fan is connected to the fan regulating valve; the fan regulating valve is in data connection to the central controller; the CO / CO2 content measuring apparatus is arranged in a smoke discharge flue of the boiler, and is used for measuring content of CO and CO2 in smoke; one end of the CO / CO2 content setting and acquiring apparatus is connected to the CO / CO2 content measuring apparatus, and the other end of the CO / CO2 content setting and acquiring apparatus is in data connection to the central controller; and the CO / CO2 content setting and acquiring apparatus is used for acquiring CO / CO2 content data and setting data. On one hand, the intelligent boiler system ensures enough and sufficient combustion of fuels inside the boiler to improve the boiler combustion efficiency, on the other hand, pollutant emission is reduced to achieve purposes of saving energy and protecting the environment.
Description
technical field [0001] The invention belongs to the combined field of boilers and automation, and in particular relates to an intelligent boiler system for on-line detection and control of tail gas discharge. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. . Widely used in daily life of residents, power stations, ships, locomotives and industrial and mining industries. During the operation of the boiler, fuel and air must be continuously sent to the furnace, and the combustion products are discharged from the furnace and flue. The reasonable combination of fuel and ventilation can make the fuel burn fully and achieve the effect of energy saving. [0003] At present, most of the existin...
