[detailed description of the invention]
It is described in further detail with embodiments of the present invention below in conjunction with the accompanying drawings:
As shown in Figure 4, existing premix gas heating system, heating system can only be when producing to rotation speed of fan and gas valve
Flow carries out the most complicated structure adjusting, make heating system reach the optimum condition that user requires.But this system is in reality
In operation, gas component, gaseous-pressure, temperature, the change of voltage can make the problems such as equipment ignition success rate, combustion thermal efficiency
Produce change.Obviously the adjustment at initial stage can not meet the actual state changed, and reaches user's optimum condition requirement.I.e. Fig. 4 institute
Showing that existing premix gas heating system is equivalent to opened loop control in control theory, wherein A is air, and B is combustion gas.
As Figure 1-3: a kind of self-regulation pre-mixing gas combustion heating system, include shell 1, in shell 1, be provided with heat exchange
Combustor 2 and master controller 4, one end of described heat exchange combustor 2 connects the blower fan 3 for controlling air and gas flow,
Described blower fan 3 connects to be had the gas ratio valve 5 for controlling gas flow and senses for detecting the blast of blower fan 3 output flow
Device 6, described master controller 4 is connected with wind pressure sensor 6 and controls blower fan respectively by the detection information of wind pressure sensor 6
3, the output of gas ratio valve 5；It is connected between described heat exchange combustor 2 and blower fan 3 and has for mixing air and combustion gas and for changing
The gas mixing pipe 7 of hot chamber 2 supply；It is air and combustion gas mixed air in gas mixing pipe 7 between described heat exchange combustor 2 and blower fan 3,
Wherein A is air, and B is combustion gas.
As shown in Figure 3: described wind pressure sensor 6 is arranged on master controller 4, the sensing of the blast on described master controller 4
The blast for controlling gas ratio valve 5 pressure reduction it is connected between device 6 and blower fan 3 and between gas ratio valve 5 and blower fan 3
