The invention relates to a biomass particle hot-blast furnace which comprises a furnace body, wherein the furnace body is sequentially provided with a fire box, a flue connecting pipe, a sieve-plate heat exchange plate, heat-conducting plates and a furnace shell from inside to outside; and the lower part of the fire box is provided with a hearth; the outer wall of the hearth is a sieve-plate structure; the upper part of a furnace chamber formed by the heat-conducting plates is provided with a heat air inlet; an air inlet plate is arranged below the heat air inlet; and an outlet of the flue connecting pipe is connected with a deduster. The biomass particle hot-blast furnace has the advantages of high efficiency, environment friendliness, low carbon, low consumption, time saving, labor saving, low cost, long service life, high temperature control precision and high heat recovery rate (up to 80%), and can save the coal amount by 30% and save the firewood amount by 40%.

The invention discloses a color smoking treatment technology for a wood modification face layer. The color smoking treatment technology comprises the specific steps that firstly, to-be-treated wood is stacked and is blown through hot air; secondly, a layer of alcohol is brushed on the surface of the wood, cleaning is conducted through a sodium carbonate solution, then thorough scrubbing is conducted through water, and the wood modification face layer is obtained; thirdly, the overall wood is immersed in a phosphoric acid solution and taken out to be aired dry; fourthly, the wood is subjected to smoking, and the wood is subjected to further baking smoking through fuel materials; fifthly, the wood is placed in a heat treatment box to be tidily placed, rapid temperature rising is conducted, vacuum pumping is carried out, then slow temperature rising is conducted, and drying is conducted till absolute dry is achieved; sixthly, the surface of the wood subjected to heat treatment is wiped thoroughly through water; seventhly, the surface of the modification face layer is coated with a wood modification agent; and eighthly, the surface of the wood modification agent is coated with a layer of protective paint again. According to the color smoking treatment technology, physical treatment and oil paint treatment are combined, the permanency of the wood color is guaranteed, the wood waterproofness is guaranteed as well, and the wood is free of toxicity, environment-friendly, safe and sanitary.

The invention relates to a functional layer for high-temperature fuel cells and to a method for the production of functional layers. The functional layer is in particular a low sintering, electrically conductive ceramic layer, which is configured between an interconnector and a cathode of a fuel cell. The functional layer according to the invention is made of a material having at least two phases. A first phase is a bismuth cobalt-containing perovskite ceramic and a second phase is a bismuth manganite and / or bismuth cobaltite (Bi-Mn-Co-O).
