Flame.Combustion-supporting fan blade 1 obtains air channel by several involute in form and formed, and passes through casting or machining circular discoid bottom surface
Upper to design and process several spiral vortex type air channels, the purpose is to obtain the vortex hot blast of uniform stirring.Detailed form see accompanying drawing 2 ~
4。
In order to obtain thermal-flame temperature field, it is necessary to combustion air is preheated, preheating temperature is higher, combustion flame temperature
Higher, engine thermal efficiency is considerably improved.To one recuperator 5 of this independent design.Recuperator by inner bag and
Outer courage and the first heat exchange fin and the weldering of the second heat exchange fin group form.
First heat exchange fin first and the second heat exchange fin are a pair of stamping forming fins.Upper bottom left is obtained by punching press
The passage of right ventilation.Man-to-man group is carried out to the first heat exchange fin and the second heat exchange fin first to weld to form a small group part.It is left
Take the continuous welding of rolling or contact weld in right both sides.It is No leakage wind between ensureing inside both sides, either under normal temperature also
It is that also not ftracture under the conditions of hot operation.Formed a pair of of one group exchange backings according to the form of accompanying drawing 6 be assembled into inner bag and
Between outer courage, continuous No leakage welding is carried out using all contact positions.Above and below one group of heat exchange fin and another group of heat exchange fin
Contact position will be closed using the form of high temperature brazing and be welded, and forms exhaust gases passes and combustion air passage is independently opened, pass through heat exchanger fin
Body separates.Specific air channel wind direction and high-temperature flue gas air draft are to being shown in accompanying drawing 3.
The method of operation of the system is as follows：
The burner gas port and combustion air entrance are to separate design.The flange of burner top installation is connection Gas Pipe
The interface on road.Difference is designed according to different gas families flange port size diameters, burner hole size will be also adjusted.Fuel
It is ejected into from burner hole with certain pressure value in combustion chamber.Now, in the presence of outside combustion fan, the cool of burning is participated in
Air enters the combustion air entrance 7 of recuperator 5 under the conditions of certain pressure.Combustion-supporting fan blade 2 is entered by heat exchange fin
Eddy flow is formed, by fuel rotation mixed combustion.Now ignitor provides pulsed electricity sparking signal, the fuel point that will be mixed
Combustion burning.Gaseous-pressure and air pressure, gas flow and air mass flow are adjusted by external air-fuel ratio system
To optimal fired state.It can be adapted to automatically adjust, also be adapted for adjusting manually.High-temperature flue gas after burning has heated engine suction
After heat pipe, remaining flue gas produces heat convection by the heat exchange fin of recuperator 5 with combustion air, on the one hand by heat
The combustion air for persistently entering combustion chamber has been passed to, has on the other hand reduced exhaust gas temperature, has improved whole system efficiency.In order to
Need to obtain the combustion field of higher temperature, combustion-supporting air temperature is higher, and the combustion flame temperature of acquisition is higher.Pass through recuperation
Combustion-supporting air temperature after device heat absorption is attained by 600 ~ 700 DEG C.And high-temperature flue gas discharges a part of heat by recuperator
The temperature at exhaust opening 6 is reduced to 200 DEG C once afterwards, and great improvement conventional burners high fume temperature, discharge be not up to standard etc.
Problem.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
