By the many winding of autoexcitation of the present invention, turbulence type coal furnace, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, the present invention is with the thermal current boiler structure, realized that coal furnace satisfies the inside and outside gas exchange process of boiler in the coal combustion process by self-loopa, suck required air, discharge after-flame gas; The present invention can make fuel burn away in vaporized state, thereby the temperature height, has improved the thermal efficiency, does not have flue dust in the burner hearth simultaneously, and pernicious gas is after-flame or curing slagging substantially, is discharged out of the furnace with slag by the steam vent below the burner hearth; Therefore, the fuel combustion of boiler of the present invention is abundant, the thermal efficiency is high, smokeless environment-friendly, energy-efficient.Boiler multi-use of the present invention can satisfy various uses such as heating such as family, factory, office, school, building site, bathing, diversion and industry heating.Structure of the present invention can be used for variously making the combustion apparatus of the energy with fire coal, as boiler, smelting furnace, kiln etc.
The present invention and traditional product relatively have following characteristics:
1, medium small boiler is fully without additionaling power, and main equipment only needs minimum relatively power guiding, can satisfy the coal conditions needed of fully burning.
2, can be without chimney air inducing, blowdown, supporting with it without air blast, air inducing, smoke abatement device, so save electric power, eliminated noise that dynamo-electric operation produces and volume of smoke, heat, pernicious gas release conditions needed to atmosphere.
3, because the interior temperature high combustion of burner hearth is abundant, so flame cleaning in the burner hearth, no flue dust stops, furnace bottom can not form schmutzband, and the flame heated body that can go directly is so thermal efficiency Gao Keda is more than 90%, also make boiler structure simple thereby heating surface area can significantly reduce, low cost of manufacture, life-span are long.
4, be convenient to realize automatic control, by the furnace pressure of setting, the variation of the furnace temperature STATE FEEDBACK CONTROL circulatory system, implementation method is easy.
5, reduced the manufacturing cost of boiler.
6, can use the awkward low calorific value coal of traditional coal combustion equipment; Reach good result of use.
