specific Embodiment approach

[0045] Such as figure 1 As shown, a double cyclone combustion water heater, its principle is that the gas-solid mixture of small particles of biomass fuel (such as rice husk, crushed straw, etc.) and air is cut from the bottom of the furnace by negative pressure suction. Inhale and ignite the feed inlet. Since two tangential feed inlets are set, the combusted material forms a double upcycling airflow; the material burns and rises with the double upcycling airflow. When the material is completely burned into ash and the quality becomes lighter, it will automatically It is separated from the incompletely burned material and sucked out of the furnace body from the top of the furnace body to the discharge port. At the same time, the incompletely burned material falls slowly with the downward swirling airflow in the middle of the furnace body and continues to burn, forming a suspended continuous combustion layer in the middle of the furnace body to continuously ignite subsequent ma...

Abstract

The invention discloses a top cyclone burning method and device. The principle of the method and device lies in that a gas-solid mixture of air and a small particle biomass fuel (for example, rice hulls, crushed straws and the like) are inhaled from tangential feed inlets at the bottom of a furnace body by way of negative pressure inhalation and are ignited. As two tangential feed inlets are formed, the burning material forms double top spin air flows; the material burns along with the double top spin air flows and ascends. When the material fully burns to ash, the ash lightened in mass is automatically separated from incompletely burning material and is extracted out of the furnace body from a tangential discharge port at the top of the furnace body. Meanwhile, the incompletely burning material slowly falls to continuously burn along with a down spin air flow in the middle of the furnace body, and forms a suspended persistent burning layer in the middle section of the furnace body to persistently ignite follow-up materials, so that the benefits of continuous feeding, continuous burning, continuous ash removal and continuous heat supply are achieved.

Description

technical field [0001] The invention belongs to the technical equipment field of small-particle biomass fuel combustion and heat supply, and specifically relates to a method and device for the combustion and self-separation of small-particle biomass fuel with double upcycling airflow, and also relates to medium heat conduction technical equipment, especially a A method and device for cyclone combustion. Background technique [0002] As the prior art, there are many types of combustion equipment for burning coarse pulverized fuels such as pulverized coal and rice husk, such as straight-through type, vortex type, and reflux type. When these pulverized coal combustion furnaces are used for pulverized coal with a particle size of less than 50 μm, the combustion efficiency is high, and the carbon content in the ash is less than 1%. When burning coarse pulverized coal with a particle size greater than 50 μm, due to the limited volume of the furnace, the combustion time of the fue...
