Abstract

The invention relates to a catalytic combustion control system, comprising fluid pre-mixed control system and PLC controller. The fluid pre-mixed control system comprises a fan connected with venturi-mixed reactor in series. Suction port at the hollow throat of venture-mixed reactor is connected with proportional regular valve and the inlet of proportional regular valve is connected with the outlet of zero-pressure valve. The zero-pressure valve is connected with needle valve in parallel. PLC controller comprises a CPU of PLC controller. By the combination technology of fluid control and PLC automatic control, in the whole fluid pre-mixed system, there is only need to control the inputting frequency of fan so as to control the outputting air quantity by the PLC control parts and different mixed concentration of gas and air demanded in the catalytic combustion process is realized. Automatic control ignition, pre-heat flaming combustion and catalytic combustion can be realized on the catalyst carrier of catalytic combustion directly. It is provided with simplified structure of catalytic combustor, decreased cubage, decreased cost, improved automaticity and control accuracy.

Description

(1) Technical field

[0001] The invention relates to a catalytic combustion control system and method of a gas catalytic burner. (2) Background technology

[0002] The survival and development of human beings depend on the development and utilization of energy, but the negative effects such as environmental pollution brought about by the development and utilization of energy are increasingly threatening the survival of human beings and the sustainable development of society. Such as emissions SO from ordinary combustion of fossil fuels 2 , NOx, CO 2 , CO and incompletely burned hydrocarbon UHC, causing acid rain, photochemical smog and greenhouse effect, causing serious damage to the ecology and threatening human health. To solve the problem of environmental pollution caused by combustion, it is necessary to change the traditional and backward combustion methods, improve combustion efficiency, develop new burners and combustion control technologies, and carry out comprehens...
