Description
Technical field
The present invention relates to a kind of saving energy in kiln system, particularly a kind of ceramic kiln energy saving system.
Background technology
Along with the market demand of pottery is increasing, ceramic kiln is also built longer and longer, cross section is also more and more wide, but kiln temperature is also more and more difficult to control simultaneously, and the firing defects such as such as distortion, aberration etc. caused because kiln temperature is uneven is also on the rise.
Meanwhile, ceramic kiln is often using combustion gas as thermal source, and during burning, whether the proportioning of combustion gas and air rationally directly has influence on the size of energy consumption.When air capacity is very few, incomplete combustion, the material containing a large amount of contaminated environment in imperfect combustion product, also causes the waste of the energy simultaneously; And air capacity excessive time, take away again a large amount of heats when excessive air is discharged, increase the loss of heat.
In addition, the fossil energy such as coal gas, natural gas is all non-renewable resources, peters out under the mankind exploit on a large scale.And these fuel can discharge a large amount of toxic and harmfuls when burning in air, cause Air seriously polluted.
Biomass fuel (being called for short BMF, such as agriculture and forestry organic waste material, as stalk, sawdust, bagasse, rice chaff etc.) has following feature: 1, the energy of BMF comes from when it grows nature CO
2absorption, therefore BMF has CO
2the feature that ecological " zero " discharges; 2, the burning of BMF is based on fugitive constituent, and the content of its fixed carbon is about 15%, is typical low-carbon (LC) fuel; 3, the sulfur content of BMF is also lower than diesel oil, is only 0.05%, does not need to arrange desulfurizer and just can realize SO
2discharge; 4, the ash of BMF is only 1.8%, is about 1/10 of coal derived fuel, and arranging simple dust arrester, just to realize dust emission up to standard; 5, BMF nitrogen content is low, and oxygen content is high, generates less NO during burning
x; 6, BMF derives from agriculture and forestry organic waste material, and feed distribution is extensively various, and cost is low, and cycling deposition is inexhaustible, is typical recycling economy project.
But industry does not also develop the ripe equipment and the technology that biological fuel gas are used for ceramic kiln so far.
