New-energy intelligent double-rotation boiler

Abstract

The invention relates to a new-energy intelligent double-rotation boiler. The boiler comprises a boiler body, a combustion chamber, a feeding system, a slag discharging and ash removing system, a combustion supporting oxygen conveying air inlet system, a smoke channel system and a hot air channel system. Fuel enters from the lower portion of an initial combustion volatile decomposition room and is subject to layered segmented combustion, the fuel utilization rate is improved, and energy waste is avoided; the multilevel multi-angle combustion supporting oxygen conveying air inlet system is adopted, the oxygen conveying amount in the fuel combustion process is ensured, the combustion speed and the combustion quality are improved, air is supplied through a porous air supply pipe and a material groove air supply container, and the effects of non-dead-corner combustion, balance oxygen supply and sufficient combustion are achieved. After initial combustion decomposition, fuel is turned over through ejecting force of a feeding machine and is re-combusted through a re-combustion chamber, combustible gas in smoke can be thoroughly burned out through a secondary ignition opening, natural air enters the boiler body and passes through a low-temperature air channel, a low-temperature air collection box, a medium-temperature air channel, a medium-temperature air collection box, a high-temperature air channel and a high-temperature air collection box to be subject to layer-by-layer warming, heat exchange is thorough, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to a new energy intelligent double-rotation boiler. Background technique [0002] Boiler is a kind of heating equipment commonly used in daily production and life. In the prior art, organic heat carrier boilers are mainly coal-fired, adopt layered combustion mode, and the combustion equipment is in the form of fixed hand furnace, chain furnace, reciprocating grate furnace and vibrating grate furnace. The existing circulating fluidized bed boiler, Although it is a dynamic combustion, the burnout rate is high, but the high positive pressure combustion dust is large. Although a separator is added at the outlet of the furnace to collect part of the soot and return it to the furnace for combustion, the boiler has a large concentration of circulating soot and wear on the heating surface. serious, low coal combustion rate, and serious environmental pollution. [0003] With the c...

Problems solved by technology

Practice has proved that returning straw to the field will increase the risk of production reduction for growers to a certain extent, and the transportation costs of processing feed and granulating power generation are too high. Problems from various aspects comprehensively restrict the root cause of straw burning.
