Chinese Patent Application No. is 201620853863.8, discloses a kind of hydrogen-oxygen mixing auxiliary combustion equipment, it includes electrolysis
Pond, electrolytic cell can be made hydrogen and oxygen simultaneously, the logical storage equipment of deposit after treatment of hydrogen and oxygen obtained, hydrogen and
Oxygen and air are sent into gas mixer by air blower, and after being sufficiently mixed with natural gas, enter boiler combustion through air duct
Burner can be improved ignition temperature by oxyhydrogen combustion, reduce exhaust smoke level, reduces thermal loss, so that the thermal efficiency is improved, hydrogen
Burning can also the full combustion again of the CO during combustion of natural gas be improved the utilization rate of fuel, accomplish 100% burning, reach
To environmental protection effect, though hydrogen and oxygen gas mixture can be combustion-supporting in that patent, the content of hydrogen and oxygen in boiler but without
Method examinations, in fact it could happen that hydrogen and the excessive or very few situation of oxygen, fruit oxygen content is very few, then combustion of natural gas is not
Sufficiently, fruit hydrogen content is excessive, is easy to happen explosion, there is security risk.
Summary of the invention
The object of the invention is that providing a kind of combustion-supporting control method of natural gas boiler to solve the above-mentioned problems, lead to
