Description
Technical field
The present invention relates to a kind of toughened glass furnace.
Background technology
China's Industrial Stoves and Industrial Boiler are the main bodys of energy consumption, and Industrial Stoves ubiquity thermo-efficiency is low, the phenomenon that energy dissipation is larger.Low for the ubiquitous effective utilization rate of energy of Industrial Stoves, the problem that energy dissipation is larger, general taked Main Energy-saving Measures is both at home and abroad: (1) adopts the light weight type lagging material of high insulating effect as far as possible; (2) far infrared energy-saving paint spay-coating technology is adopted; (3) flue gas heat recovery; (4) blackbody radiation element power-saving technology.
Traditional way adopts the light material and lagging material brickwork that thermal capacitance is less, to reduce accumulation of heat and heat lost by radiation.This power-economizing method, just heat " is blocked up " in burner hearth, do not need the net heat of the product of sintering to absorb, do not change " diffuse-reflectance " state of invisible heat, do not solve the problem whether invisible heat puts in place, so need the net heat of the product of sintering still very low.People by heat calculation or test, find that body of heater accumulation of heat and heat lost by radiation are up to 60% ~ 70%, and the net heat needing the product of sintering only 25% ~ 30%.
The thermo-efficiency of heat accumulating type toughened glass furnace obtains raising by a relatively large margin; The application of infrared radiation coating subsequently, the net heat that the basis of high thermal effect solves the product needing sintering absorbs problem, further increases thermo-efficiency.
Heat transfer has in industry kiln burner hearth: the transmission of heat by convection of the product radiation of flame radiaton, burning, the radiation of furnace wall solid surface and furnace gas radiation and furnace gas.In simple terms, what participate in heat exchanging process in kiln has 3 kinds of basic objects: furnace gas, furnace wall, heating and calcining thing.That heat transfer between kiln gas and heating object mainly relies on transmission of heat by convection below 800 DEG C; Be rely on convection current and radiation between 800 DEG C ~ 1000 DEG C, when temperature mainly relies on far-infrared radiation heat exchange higher than the thermal conduction between kiln gas when 1000 DEG C and heating object, the heat 90% that heating object absorbs is realized by radiation heat transfer simultaneously.By refractory brick in major part industry kiln burner hearth, refractory castable, fire-resistant light insulating brick or ceramic fiber are built by laying bricks or stones.These refractory materialss have resistivity against fire, under high temperature, intensity is high, the characteristics such as stability is high can meet kiln needs, but the far infrared transmissivity of these refractory materialss generally about 0.35 (as at 1100 DEG C: fireclay brick: 0.35 ~ 0.65, mullite 0.4, aluminum oxide 0.18 ~ 0.52, refractory fibre 0.35), and the emittance of coatings capable of preventing from far infrared radiation is 0.85 ~ 0.95.Infrared radiation heat transfer is exactly the radiation capacity heating object utilizing infrared rays uniqueness, object is heated, at a certain temperature, heating object gives off the infrared wave with certain penetrativity, make heating object generation molecular oscillation, produce energy level transition, the infrared rays of the certain wave band of radiation, thus produce heat.Its feature one is heat absorption object thermally equivalent, and two is heat from inside to outside, thus decreases heat-up time, improves energy utilization rate.
The basic weakness of far infrared coating technology is that coating is easily aging, and continuous efflorescence is in actual use dropped or by air-flow erosion, thermal infrared emittance progressively decays, and loses infra red radiation function, and thermal effect passes decline in time.
