Embodiment one
Referring to Fig. 1, the method for the raising efficiency of combustion showing in first embodiment of the invention, can be applied to combustion gas
In wall-hung boiler, the method includes the steps S01 to step S04.
Step S01 obtains revolving speed of the blower in blast switch operating point.
Wherein, the blast switch operating point refers to the critical point of blast switch when closed or opened, is being embodied
When, can when burnt gas wall hanging furnace is in non-burning state (misfiring) or minimum load (minimum combustion power) combustion state,
By way of adjusting rotation speed of fan, to search for revolving speed of the blower in blast switch operating point.Due in non-burning state and
Under minimum load combustion state, the intracorporal excess air coefficient of furnace is very high, so there will not be near blast switch operating point
The exceeded risk of flue gas.
Step S02, according to revolving speed of the blower in blast switch operating point, establish combustion power and working speed it
Between corresponding relationship.
It should be pointed out that blower blast switch operating point revolving speed be benchmark revolving speed, the reference rotation speed of blower and its

In gas wall-hung boiler, the method includes the steps S11 to step S20.
Step S11 adjusts rotation speed of fan under minimum load combustion state, obtains blower with search and acts in blast switch
Revolving speed when point.
In the specific implementation, within a period of time after fuel wall hanging furnace heating burning starting, minimal negative can be at
Under lotus combustion state, and rotation speed of fan is during this period of time constantly regulate, blower is obtained in blast switch operating point with search
Revolving speed.Since under minimum load combustion state, the intracorporal excess air coefficient of furnace is very high, so in blast switch operating point
It nearby there will not be the exceeded risk of flue gas.
Step S12, according to revolving speed of the blower in blast switch operating point, establish combustion power and working speed it
Between corresponding relationship.
Specifically, it is assumed that revolving speed of the blower of acquisition in blast switch operating point is searched under minimum combustion power is
w0, and measuring maximum (top) speed of the blower when voltage is rated value 220Vac is about 1.7w0, and demarcate minimum combustion power PminWhen
Blower operating point is 1.2w0, maximum combustion power PmaxThe operating point Shi Fengji is 1.5w0.Then have:
The combustion power P of burnt gas wall hanging furnace is in PminTo PmaxBetween when, the working speed w of blower will be in 1.2w0To 1.5w0
Between linear distribution, it may be assumed thatWherein P is subsequent step
The target combustion power that S13 is obtained, PminAnd PmaxThe respectively specified minimum combustion power of burnt gas wall hanging furnace and specified maximum combustion
Burn power.To establish the corresponding relationship between combustion power and working speed.
Step S13 obtains target combustion power.
Wherein, the target combustion power refers to combustion power to be achieved needed for burnt gas wall hanging furnace, the target combustion

Step S20.
Step S18, judges whether the blower is in maximum output state.
Wherein, when determining the blower and being not in maximum output state, S19 is thened follow the steps, when determining
When to state blower be in maximum output state, shape between furnace body and outdoor can not still be made by representing blower and being in maximum output state
At standard wind pressure, S20 is thened follow the steps.
Step S19 improves the target operation revolving speed, and returns to step S15, to continue to supervise blast switch
It surveys.
In the specific implementation, can by a certain percentage (as every time speed-raising 15%) Lai Tigao target operation revolving speed, to mention
The actual speed of high blower.Revolving speed is w=1.15 (1.2+0.3 λ) w after raising speed such as first time0, revolving speed after second of speed-raising
For w=1.152·(1.2+0.3λ)·w0... and so on.Meanwhile the calibration of minimum combustion power can also be leaned on after speed-raising
To restore conventional rotating speed.
It is born it should be pointed out that the actual speed for improving blower can obtain part under the premise of not reducing resistive drag force ability
The promotion of lotus efficiency improves practicability and energy-saving effect.
Step S20, closing gas valve report wind pressure failure to stop burning.
It should be understood that combustion gas is unable to fully burn, and flue gas when that can not form standard wind pressure between furnace body and outdoor
It can not exclude in time, there are combustion completion hidden danger, therefore when that can not form standard wind pressure between furnace body and outdoor, can close immediately
The gas valve of burnt gas wall hanging furnace is closed to stop burning, and the alarm of capable of emitting wind pressure failure.
To sum up, the method for the raising efficiency of combustion in the present embodiment, by detecting wind pressure during normal work
Whether switch disconnects, and after blast switch disconnection, by the strategy for the resistance that raises speed, to continue to reduce surplus, thus further
Improve efficiency of combustion.

Air quantity needed for generating blower, to meet the api request that burnt gas wall hanging furnace works under target combustion power.
Step S35, judges whether the current combustion time reaches preset threshold.
Wherein, the preset threshold is preferably 1 hour, when determining the current combustion time and reaching preset threshold, is returned
Step S31 is executed, to reacquire revolving speed of the blower in blast switch operating point, with the change of timely response environment
When changing, and burning away after the revolving speed when reacquiring to blower in blast switch operating point, restart to carry out comburimeter
When, with duplication check；When determining the current combustion time and being not up to preset threshold, then S35 is returned to step, to continue to supervise
Whether the current combustion time for surveying burnt gas wall hanging furnace reaches preset threshold.

It states blower and whether is in maximum output state, and when determining the blower and being not at maximum output state, improve the mesh
Working speed is marked, and is in maximum output state determining the blower, stops burning.
7. improving the system of efficiency of combustion as claimed in claim 5, which is characterized in that the rotational speed regulation module is also used to sentence
Whether the disconnected current combustion time reaches preset threshold, and when determining the current combustion time and reaching the preset threshold, described
Revolving speed obtains module and reacquires revolving speed of the blower in blast switch operating point.
8. improving the system of efficiency of combustion as claimed in claim 6, which is characterized in that the rotational speed regulation module is also used to
When determining blast switch disconnection, the current real work revolving speed of the blower is obtained, and judges that the real work turns
Whether speed is higher than minimum speed value, and when determining the real work revolving speed not higher than the minimum speed value, stops combustion
It burns.
9. a kind of burnt gas wall hanging furnace, which is characterized in that including processor, memory and store on a memory and can locate
The computer program run on reason device, when the processor runs the computer program, the burnt gas wall hanging furnace perform claim
It is required that 1 to 4 described in any item methods for improving efficiency of combustion.
10. a kind of storage medium, which is characterized in that it is stored with meter used in burnt gas wall hanging furnace as claimed in claim 9
Calculation machine program is realized when the computer program is executed by processor such as the described in any item raising burning effects of Claims 1-4
The method of rate.
