Summary of the invention
For achieving the above object, the technical solution of the utility model is as follows:
A kind of boiler of organic heat carrier, it comprises boiler body, boiler foundation and external air blast, boiler body is supported on the boiler foundation, air blast is placed on the air blast bearing, the boiler body inner chamber is a main chamber, its indoor design has the spiral heat exchanger tube of solid matter, heat exchanger tube is about two-layer, leave flue between two-layer, flue links to each other with outlet flue, boiler adopts single layer fixed fire grate, is characterised in that: furnace wall material bottom, boiler foundation combustion chamber is circumferentially designed along furnace wall the air intake endless tube, and design has blower fan to take on the air intake endless tube, the air intake endless tube is taken over by blower fan and is linked to each other with air blast, vertically be connected with tube connector on the air intake endless tube, design has air outlet to the boiler axis in the tube connector end, and air outlet communicates with main chamber by air outlet reserved passageway on the adiabator layer.
Above-mentioned a kind of boiler of organic heat carrier is characterized in that: tube connector termination portion is equipped with the air intake box, is connected with the airduct of tubulose on the sidewall of air intake box, and airduct points to the boiler central axis direction.
Above-mentioned a kind of boiler of organic heat carrier is characterized in that: air intake box upcast ventilation pipe tilts with respect to the boiler furnace diameter of section, and all airducts tilt in the same way.
Above-mentioned a kind of boiler of organic heat carrier is characterized in that: air intake box upcast ventilation pipe is divided into upper strata airduct and lower floor's airduct, and the upper strata airduct is different with lower floor airduct angle of inclination, and during boiler operatiopn, the last lower air conduit air intake that cooperatively interacts forms scopiform air distribution structure.
Above-mentioned a kind of boiler of organic heat carrier is characterized in that: the inclination angle of upper strata airduct is 25 °, and the angle of inclination of lower floor's airduct is 20 °.
Above-mentioned a kind of boiler of organic heat carrier is characterized in that: airduct adds up to 6~8.
Above-mentioned a kind of boiler of organic heat carrier is characterized in that: design has hygrosensor on the furnace wall, and hygrosensor all links to each other with Furnace Temperature Controller with air blast.
The advantage of such scheme is as follows:
1, scopiform secondary air distribution structure makes air fully mix with fuel gas, flammable grit, helps the thorough burning of ickings particle, fuel gas, improves boiler efficiency;
2, the time of staying of prolong smoke in burner hearth, make auxiliary air and fuel gas, flammable grit that be arranged a reasonable burning time.The time of staying of flue gas in stove is long more, helps the combustible in the flue gas and the abundant burning of fuel gas more.
3, provide powerful centrifugal power, strengthen the disturbance effect, prolong flying dust and in stove, collide growth.Flying dust runs foul of each other in flow process and constantly grows up, and around gravity and action of centrifugal force are compiled burner hearth, falls at last.Reach the dust exhausting concentration that reduces boiler, reduce the purpose of the imperfect combustion heat loss of boiler.Reduce the wearing and tearing of flying dust simultaneously to boiler heating surface.
The boiler course of work:
On fire grate, coal-fired primary combustion under a wind effect generates burning mixtures such as a large amount of carbon monoxide when producing heat.Fuel gas enters high temperature combustion zone.
High-pressure blast device produces the high-voltage secondary air distribution, preheat the back and replenish high temperature disturbance secondary wind by brush air distribution device along the combustion chamber tangential direction in the boiler high temperature combustion zone, produce powerful vortex power, form strong aerodynamic field, make the interior air-flow of burner hearth become the eddy current rotation status, the time of staying of prolong smoke in burner hearth.The high temperature air that replenishes under the effect of vortex perturbed force with flue gas in combustibles such as ickings particle more fully mixes, thoroughly burn.The growth that under the effect of strong disturbance power, runs foul of each other of flying dust in the flue gas, and under gravity and action of centrifugal force, compile around the burner hearth and fall, the dust exhausting concentration of boiler reduced.Realize saving fire coal, improve product efficiency, reduce the environmental protection purpose of soot emissions.
Below in conjunction with drawings and Examples the utility model is further described.
