Abstract
The utility model relates to an oil and gas combustion boiler for areas with high elevation above sea level, which consists of a combustion chamber, a combustion device and an insulation layer; wherein, the burning device comprises an air blower and an air transferring cartridge that is connected with the air blower. The utility model is characterized in that the length of an air delivering direction is increased; the exit of the air delivering cartridge has a central airflow rotating area and an outer ring airflow rotating area is arranged around the central airflow rotating area; the central airflow rotating area is provided with a rotating guiding groove and the outer ring airflow rotating area is provided with a guiding wing slice; the ratio between the length and the diameter of the combustion chamber is two to one; the included angle between the air delivering cartridge and the combustion chamber if a right angle and a right angle negative pressure vortex is generated between these two parts. The utility model has the following advantages that firstly, applying to the high elevation above sea level areas with a normal combustion and ensuring the normal power; secondly, ensuring the thermal efficiency of the boiler with a steady combustion flame; and thirdly, the structure is simple and the design is reasonable, economic and practicable.
Description
Technical field
The utility model belongs to a kind of fuel oil, gas fired-boiler, particularly a kind of fuel oil, gas fired-boiler that is suitable for high area above sea level use.
Background technology
General fuel oil, gas fired-boiler can both normal combustion below 1000 meters and guarantee normal power at height above sea level, and arrived height above sea level more than 3000 meters the time, because rarefaction of air, oxygen content reduces in the air, and it is insufficient that fuel combustion (oxidation reaction) is carried out, and causes the oil burning boiler over-emitting black exhaust, fuel value can not discharge, carbon black pollutes boiler heating surface simultaneously, influences the heat exchange of boiler, causes boiler power to descend.The reason that causes this situation be general fuel oil, gas fired-boiler under the hypoxemia situation, oil/gas (oxygen) undercompounding, and simple the increasing given air quantity, can cause the flame combustion instability again, causes boiler thermal output to descend simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of fuel oil, gas fired-boiler that use in high area above sea level that be suitable for, and it has overcome above-mentioned defective, has solved the problem that high altitude localities oil burning boiler over-emitting black exhaust and power descend.
The technical solution of the utility model is: a kind of fuel oil, gas fired-boiler that is suitable for high area above sea level use, it is made up of combustion chamber, burner and heat-insulation layer, burner comprises blower fan and connected air funnel, it is characterized in that: air-supply to length lengthening; Be provided with the central gas stream Rotary District in the exit of air funnel, outer shroud air-flow Rotary District arranged around the central gas stream Rotary District; The rotary steering groove is equipped with in the central gas stream Rotary District, and guide vane is equipped with in outer shroud air-flow Rotary District; The L/D ratio of combustion chamber is 2; Air funnel and combustion chamber angle meet at right angles, and form negative pressure vortex, right angle.
The utlity model has following advantage: 1, be suitable for the high altitude localities, can normal combustion, and guarantee normal power; 2, combustion flame is stable, guarantees boiler thermal output; 3, simple in structure, reasonable in design, economical and practical.

Accompanying drawing 2 is the utility model air funnel exit enlarged drawings.
Accompanying drawing 3 is side views of accompanying drawing 2.
The specific embodiment
As shown in the figure, a kind of fuel oil, gas fired-boiler that is suitable for high area above sea level use, it is made up of combustion chamber 1, burner and heat-insulation layer 2, burner comprises blower fan 3 and connected air funnel 4, it is characterized in that: the length lengthening of air funnel 4, and blower fan 3 is by the centrifugal action of flabellum, air is pressed into air funnel, the air funnel 4 that has extended makes the air to obtain the current stabilization effect in process of flowing, has guaranteed the stability of flame combustion; Be provided with central gas stream Rotary District 5 in the exit of air funnel 4, outer shroud air-flow Rotary District 6 arranged around central gas stream Rotary District 5; Rotary steering groove 7 is equipped with in central gas stream Rotary District 5, and guide vane 8 is equipped with in outer shroud air-flow Rotary District 6, and air fully mixes with fuel by the different whirligig rotation back of angle, guarantees full combustion of fuel; The L/D ratio of combustion chamber 1 is 2, makes flame fully be stretched, and also is beneficial to flame and refluxes and heat exchange; Air funnel 4 meets at right angles with combustion chamber 1 angle, forms negative pressure vortex, right angle 9, and the flame of backflow and the air that has neither part nor lot in burning be in this further mixing, make burn more complete, abundant.
