Description
Technical field
The utility model relates to a kind of full premix Chinese meal cooking stove burner.
Background technology
There is the supply pressure shakiness in production and use of marsh gas system, bigger some problems that wait of component fluctuation ratio at present.Since winter biogas gas production than significantly reducing summer, and the gas consumption of Chinese meal cooking stove is bigger, actual present biogas Chinese meal stove has adopted the burner form of the cooking stove of natural gas or liquefied petroleum gas or artificial coal gas substantially, and there is not a large-scale application, when therefore common air blast burner is used for the Chinese meal cooking stove, exist air-biogas ratio to change greatly problems such as combustion instability.Cause inefficiency, pollutant emission serious etc.
200420086517.9 pairs of interior low biogas of methane content of methane-generating pit starting period of the patent No. make full use of, make that the burning of the normal biogas of methane content is more abundant, firepower is more violent, simultaneously can also save a large amount of high-quality marsh gas, the service efficiency of biogas is improved greatly, make the gas consumption of normal biogas save more than 40%.Accelerate the normal time of using of methane-generating pit input, reach low pressure, lean-burn, province's gas.The patent No. 200920072378.7 provides a kind of internal flame formula biogas burner, and flame can not influence environment on every side because of burning in the burner internal-combustion; The burner design height is low; Burner operation is controlled automatically by PLC.The patent No. 200910265344.4 adopts mixer or introduces in the section and is provided with the swirling flow sheet, and the upper port of mixer is provided with latticed flame holder.
Present biogas Chinese meal cooking stove is subjected to the little restriction of consumption, all adopts the burner of natural gas or liquefied petroleum gas or artificial coal gas, uses the diffusion type combustion technology of forced-air blast, has following problem:
(1) component of biogas and pressure, stable unlike natural gas or liquefied petroleum gas or artificial coal gas, the diffusion combustion technology of forced-air blast, problems such as incomplete combustion, efficient reduction appear in fluctuation easily that can not bear component and pressure.
(2) if use electronically controlled burner in the Chinese meal cooking stove of biogas, cost will improve greatly, exceed biogas user's ability to bear.
To sum up, patent 1 is applicable to small-sized household biogas kitchen range, and patent 2 adopts PLC to carry out the control of burner, and patent 3 adopts injector and the steady flame technology of small fire hole.The adaptability problem that does not all relate to the biogas pressure fluctuation.
The utility model content
The purpose of this utility model is to provide a kind of full premix Chinese meal cooking stove burner.
The full premix Chinese meal cooking stove burner that the utility model proposes, by blender 1, current-sharing pipe 2, burner 3, the quirk 4 that refractory material is made, biogas butterfly valve 5, air butterfly valve 6 and link-type air biogas ratio control device 7 are formed, wherein: burner 3 tops are provided with the quirk 4 that refractory material is made, blender 1 top connects burner 3 by current-sharing pipe 2, one side is connected biogas pipeline by pipeline with biogas butterfly valve 5, the bottom is connected air duct by pipeline with air butterfly valve 6, and biogas butterfly valve 5 is connected by link-type air biogas ratio control device 7 with air butterfly valve 6.
In the utility model, described burner 3 is provided with the scrak type cyclone fire hole.
The utility model utilizes the device of air ejection biogas, and whole premixs before burning with biogas and air burn outside the scrak type cyclone fire hole afterwards, add the hyperthermia radiation ability of the quirk that refractory material is made, and have strengthened diabatic process.Have burning fully, compact conformation, efficient advantages of higher.The principal character of technical scheme is:
(1) adopts the full premix combustion technology.Keep the air blast that diffusion flame burner uses, increase structures such as injector, high temperature quirk, before burning, biogas is fully mixed with air, can realize fast, burn completely.
(2) biogas, the AIR Proportional control device that adopts mechanical linkage to control guarantees that the ratio of air and biogas is in the best all the time in the whole load range of burner.
The beneficial effects of the utility model:
(1) utilize air ejection biogas, the duty of burner is not subjected to the influence of biogas pressure and component.
(2) cyclone fire hole linking rod control guarantees stable full premix combustion, and efficient height, heat transfer simultaneously by force.
(3) cost is compared with diffusion type biogas Chinese meal cooking stove, increase only be the cost of high temperature quirk part.Compare with electronic control system, under the identical situation of reliability, cost increases little.
(4) share of radiant heat transfer is higher in the energy of the outside output of the utility model, and the coefficient of heat transfer is big, and when being used for the Chinese meal cooking stove, burning is complete, efficient is high.The test shows of carrying out according to national standard: when power 35kW, the thermal efficiency can reach 34%, traditional forced-air blast formula biogas Chinese meal cooking stove, and efficient only is about 20%.
