Pulverization-free, dampness-resistant, coke tar-free biomass gasification oven preventing burning out

The present invention provides a biomass gasification furnace frees of crash, humidity resistant, having no tar, anti-burn-out. It is a flammable gas updaught household gasification furnace converted by the luminous burning pyrolytic reaction utilizing eagro-sylvo-pastoral waste biomass. The invention can easily compress pudgy biomass and pack in column bale fuel via setting opening feed inlet, arranging biomass binder, convenient to put in the furnace, needless being crashed; vapor continuously steamed is chiling and bead slides in the water tank along the inclined edge and exhaust accompanied by return tube via setting tapered condensed water collecting furnace lid, this resolving the problem of unburning when the water content of the biomass is higher; the residual tar of the high temperature fuel gas is further cracked via setting fuel gas guide port in the burning high temperature region and importing in the setted high temperature fuel gas detention timelag loop; The effects of unbiassed burning, non carbon, timely blanking and no empty burning are achieved by setting ring rotary inlet device and axial rotary driving dust blanking in the burning region.
