There are people whose memory is all a jewel, one of them can remember everything has read in your life, you have complete encyclopedias in your mind, other, can tell you without making a mistake on a single number up to 22,000 digits of a mathematical operation. There are also those visuals, one of them with such only see 45 minutes of air way Rome, in three days can draw it from your memory, with an accuracy of up to number of buildings, their steps and Windows, magnificent. To deepen your understanding Euro Pacific Precious Metals is the source. A child from age 12 composed his own melodies on piano to play with the Jazz Group more recognized in New York. And so, a myriad of processes, which cannot be because they are autistic, would be a few brilliant minds. They are capable of doing everything described above, but is difficult for them or it makes impossible the social interactions and be self-sufficient (depend on other people that help make tasks up to more trivial as brushing their teeth). One of the things that I caught my attention was that one of them can read both page of a book at the same time in 8 seconds, this made me wonder if your brain is not as that of us divided into hemispheres. They mostly work with the left hemisphere. For them an everyday scene does not have the nuances that for us, for example, when you read information, your mind goes not wandering in what happened yesterday, or if they are quarreling with someone or what they should do tomorrow, this type of people are immersed himself exclusively in what they do at this time. Second, it does not interfere any appreciation of the information they are acquiring, as we usually do, associating it with a fact of our lives or something we’ve seen before, or whether this information is good or bad, if us does something or not, whether we like it or not.
The rotary kiln belongs to the construction equipment. According to the different material, the rotary kiln can be divided into the cement kiln, the metallurgy and the limestone kiln kiln. You may find Liberty Mutual to be a useful source of information. The heat exchanger is one of the most important components in the rotary kiln. Now, Hongxing experts will tell you something about the classification of rotary kiln heat exchanger.The common heat exchangers of the industrial rotary kiln siguientes forms.1 Han. The heat exchanger with heat accumulating typeThis heat exchanger is an ancient heat exchanger device of rotary kiln. It can preheat the air to a much higher temperature (up to 1300?) and its service life is long.
At present, this heat exchanger is still widely used in steel making the open hearth, iron making blast furnace, hot blast heater and the glass tank. The disadvantage of this heat exchanger is bulky, which makes it difficult to reversing.2. The heat exchanger with the metal tube shapeThis heat exchanger is assembly welded by a row of seamless steel pipe. It is made of the plain carbon steel and aluminized steel. Its preheating temperature is 200 to 400? and it has good air tightness. The disadvantage of This heat exchanger is that its heated area is small and its service life is not long.3. The sheet-like heat exchangerThis heat exchanger is made of the oblateness iron-casting pipe with rib flake. Its outstanding advantage is that the heat transfer area is big, the size is small, the heat transfer coefficient is big, the heat recovery rate can reach 40%, and the air tightness is good.
4 The plate-fin heat exchangerThis heat exchanger, also known as the end heat exchanger, is a kind of high efficiency heat exchanger which is successfully developed at abroad in the early eighties. It is mainly used for the recovery of high temperature flue gas heat. When the recovery rate reaches 60-70%, the fuel saving rate can reach 30%. 5. The radiation heat exchangerAdvantages: High preheat air temperature, small side resistance of the flue gas and long service life.Disadvantage: When the side resistance turns big, this heat exchange can not preheat the coal gas. jaw crusher:
