Extrusion (24) also continuously squeezes out biomass powder fuel to transition interflow chamber (10), the life just squeezed out from powder extrusion (24)
Substance powder is dispelled rapidly in transition interflow chamber (10) by air outlet (34) blowout pressurized air, due to powder extrusion (24)
Annularly in the surrounding of the air outlet (34), and then its air outlet (34) blowout pressurized air makes biomass powder fuel uniformly float
It being dispersed in transition interflow chamber (10), the biomass powder fuel dispelled is gushed out in dispersion chamber (25) together with pressurized air, into
And biomass powder fuel and pressurized air are formed by mixture in dispersion chamber under the action of conical flow guiding wall body (8)
(25) dispersion is expanded in horn-like rapidly in, and is quickly entered in preheating cavity layer (5) under Action of Wind pressure, in wind pressure and spiral shell
Under the drainage of rotation drainage band (4), pressurized air and the formed mixture of powder fuel in the preheating cavity layer (5) do edge
Spiral drainage band (4) spiral direction spiral flow-disturbing movement so that pressurized air and the formed mixture of powder fuel are more equal
It is even；At the same time, the pressurized air and powder fuel institute shape of flow-disturbing movement of spinning in cavity layer (5) are preheated under Action of Wind pressure
Resulting mixture is directed into combustion chamber (7) through several powder fuel inlet hole (29) continuous uniforms, and then makes in the combustion chamber (7)
Surrounding pressurized air is poured in by continuous uniform and powder fuel forms mixture；The pressurized air poured in and powder fuel
Formed mixture with from gas spraying portal (75) spray natural gas meet in helical heating pipe (77) position, melt
It closes；Start ignition at this time, and then make that the powder fuel in combustion chamber (7) drifts object and natural gas burns rapidly, puts
The natural gas injection mode for penetrating shape makes to generate more uniform flame in combustion chamber (7) after burning, and entire helical heating pipe
(77) it is completely submerged in the flame in combustion chamber (7), and then helical heating pipe (77) is sufficiently heated, and then to spiral
Water in heating tube (77) carries out continuous heating, and then makes hot water delivery line (83) that hot water persistently be discharged；
Control centrifugation booster fan (35) increases the pressure of export pressurized air after chamber (7) burning to be combusted, and then keeps preheating empty
The air pressure being consistently greater than in combustion chamber (7) is kept in cavity layer (5), the flame in combustion chamber (7) after guaranteeing burning will not reflux
Into preheating cavity layer (5), adaptability adjusts the supply gas pressure of natural gas supply pipe (73) at the same time, maintains the stabilization of burning
Property；
Burning in combustion chamber (7) can make furnace core (27) to generate high temperature, and then to the pressurized air and powder of the preheating cavity layer (5)
Grain the formed mixture of fuel preheated, by the preheating cavity layer (5) pressurized air and powder fuel formed it is mixed
Conjunction object is in flowing always and renews state, thus the temperature in the preheating cavity layer (5) will not continue to increase, thus the preheating is empty
Cavity layer (5) also acts as heat-blocking action, prevents furnace core (27) from transferring heat to furnace body (6).
