The thermal load regulating system comprises a main channel arranged between a combustor and a gas source, one or more additional channels, a valve body arranged on the main channel, a stop valve arranged on each additional channel, a conventional nozzle corresponding to the main channel and a control device. The thermal load regulating system is characterized in that independent additional nozzles and air blowing devices are arranged corresponding to the additional channels, and the control device is in control connection with the air blowing devices and the stop valves; the air blowing devices supplement primary air needed by gas flowing through the corresponding additional channels; the control device controls on-off of the stop valves so as to realize switching of the thermal load of the gas stove between the large-load working mode and the conventional working mode. According to the thermal load regulating system, in the conventional working mode, the thermal load is regulated by regulating the diameter of the conventional nozzle and the valve body; in the large-load working mode, the thermal load can be increased further by adding the additional channels, and the number of the additional channels can be freely increased according to needs and is not easily limited by the system.
Description
Technical field
The present invention relates to home furnace technical field, particularly relate to a kind of gas-cooker heat load adjustment system.
Background technology
Current gas-cooker maximum heating load depending nozzle aperture is determined, regulates at maximum heating load by means of only valve body to closing in closed interval.As increased maximum heating load and combustion conditions is normal, then need to comprise nozzle, burner, pan bracket whole combustion system improve, can not adjust flexibly.And strengthen along with maximum heating load, burner volume can corresponding increase, and performance parameter is more difficult to reach, and also can improve the designing requirement of system other side.
In the prior art, the patent No. be 201310465072.9 patent a kind of gas-cooker is disclosed, although have employed multichannel design, but its multichannel is still given vent to anger by same nozzle, because nozzle bore is determined, then can to increase load extremely limited for its reality, and the more single passage of multiple passage only can increase combustion gas static pressure before nozzle slightly, actual very limited on the impact of thermic load; As less and limit static pressure subnormal pressure in designed first passage, reach normal pressure when design second channel is opened, the object that reaching in this approach increases flow is made an unnecessary move again, and it can realize the object of large load completely by single channel.And it only increases the primary air admixture that gas flow does not improve system, then, after it increases thermic load, combustion conditions will become badly, therefore its Practical significance is also little.
Summary of the invention
For problems of the prior art, the object of the invention is to design a kind of stable, reliable, heat load adjustment by system restriction, the gas-cooker heat load adjustment system not affecting combustion conditions.
For reaching above object, the present invention adopts following technical scheme.

Further illustrating as such scheme, corresponding additional nozzle is provided with independent induction tunnel.
Further illustrating as such scheme, described additional nozzle is arranged on the induction tunnel of main channel.
Further illustrating as such scheme, the air channel of described air-blast device is connected to the induction tunnel position that additional nozzle stretches into.
Further illustrating as such scheme, a stop valve controls one or more additional channels
Further illustrating as such scheme, in the normal working state, described stop valve and described air-blast device are all closed, and under large load operating conditions, described stop valve and described air-blast device are opened.
Further illustrating as such scheme, described valve body is that separate machine controls or carries out the automatically controlled control of independence by control device, and when valve body rotates to most big fire position, control device starts additional channels air feed, air-blast device startup simultaneously.
Further illustrating as such scheme, described control device is connected with valve body signal, and when control device starts additional channels air feed and air-blast device, valve body is automatically rotated to most big fire position.
Further illustrating as such scheme, in the normal working state, regulates thermic load by adjustment valve body spool folding size; Under large load operating conditions, the quantity opened by quota outer tunnel carrys out the load of heat that quota increases outward.
Further illustrating as such scheme, described additional channels is at least two, and the air channel of air-blast device is provided with air blast current divider, and described air blast current divider is connected with each additional channels for each additional channels supply simultaneously primary air.
Further illustrating as such scheme, described valve body and stop valve are all automatic valve, and control device is connected with thermic load input unit; When the maximum heating load that the thermic load inputted can provide lower than main channel, control device application valve body is opened, and controls stop valve and closes; When the maximum heating load that the thermic load inputted can provide higher than main channel, control device application valve body and stop valve are all opened.
Compared with prior art, the invention has the beneficial effects as follows:
One, there are two kinds of duties in combustion system: normal operation state, and thermic load depending nozzle aperture and valve body regulate, and itself and conventional combustion system are similar; During large load operating conditions, under the condition that former burner is constant, by increasing additional channels, thermic load can be improved further, the quantity of additional channels can increase arbitrarily as required, and be not subject to system restriction, the amplitude improving thermic load can according to different product demand, bring up to any amplitude, and only need to provide for simple replacement of indivedual accessory and can accomplish, under the prerequisite not changing conventional combustion system, can effectively promote combustion system maximum heating load.
Two, by arranging the air-blast device corresponding with additional channels, under two kinds of fired states, this system stable combustion condition, all can meet the requirements normally used combustion conditions, the expansion of maximum heating load does not affect the stability of combustion system, reliability and combustion conditions.
Three, the additional nozzle of system can flexible arrangement, as additional nozzle arranges independently injection passage and fire hole, and function burner can being supported to realize multiple flame profile switch
Four, each additional channels and blower system all can independently control, and related system breaks down, and burner still can normally use.
