The position of fundamental the sources of energy that the resource gift of our country rich coal, lean oil, little energy of life decided coal. Our country the sources of energy consumed gross to amount to coal of 4.36 billion tons of mark 2016, among them coal consumption is occupied than 62% . What pollute a problem as the environment is increasingly austere, promotion coal cleanness is efficient use technical extremely urgent.
“Water coal oar is one kind accords with the clean the sources of energy of structure of our country the sources of energy to use a technology. ” on the current situation of technology of coal cleanness combustion that held a few days ago and development informal discussion, chinese coal division is versed in Wang Jinhua shows group president, “As home the large-scale industrialization of technology of aerification of oar of coal of water of own intellectual property is advanced, industry of water coal oar greets high speed to send exhibition period, the dosage that predicts the aerification before 2020 uses water coal starch will break through 200 million tons. The dosage that predicts the aerification before 2020 uses water coal starch will break through 200 million tons..
“Water coal oar is efficient and clean the technology is coal cleanness efficient a kind of when use a technology efficient way. ” Li Falin of director of research center of technology of project of oar of coal of water of nation of coal division courtyard expresses, “After 2010, large coal chemical industry and technology of aerification of water coal oar develop quickly, water coal oar is transformed to raw material attribute by fuel gradually, our country already made technology of water coal oar banner, produce the country with the biggest dosage. Our country already made technology of water coal oar banner, produce the country with the biggest dosage..
In the meantime, the expert also expresses, cleanness of water coal oar is efficient technical equipment reliable, technology is mature, need to emphasize hair power in 4 big fields.
The 3rd acting technology solves difficult problem of coal chemical industry
Water coal oar is by the water of the coal of 65%-70% , 30%-35% and the additive of 1% , through what certain treatment technology makes fuel of coal radical fluid turns raw material compatibly, its use a way to basically combustion exothermic, aerification synthesizes coal industrial chemicals two kinds.
Incorporate combustion technology, aerification technology inside, efficient and clean technology still includes water coal oar technology of preparation of water coal oar. And, technology of preparation of water coal oar is right burn follow-uply or aerification has immediate effect.
As we have learned, coal the 3 big factors that grading of granuality of qualitative, coal fines, additive is preparation of oar of influence water coal. To improve the combustion efficiency of coal, coal bead should be achieved certain and fineness. According to introducing, technology of preparation of water coal oar is in the 3rd generation to make oar technology level at present, namely bead accuses grading oar craft. This technology that make a starch can control coal bead size and scale strictly, basically use at aerification of water coal oar, be in by research center of technology of project of oar of coal of water of nation of coal division courtyard the 2nd acting technology that make a starch classifications undertake equipment and craft upgrade to improve and come on the foundation of abrade craft, its make oar chroma can be as high as 70% , coal oar chroma makes an appointment with 6-8 than rising on foundation of former rod mill percent.
As we have learned, water coal oar includes through what arise after aerification technology carbon monoxide and hydric inside synthesis is angry, it is the important raw material that produces the item of coal chemical industry such as methanol.
“Coal aerification is the gas head of coal chemical industry, coal oar chroma and relationship of coal aerification efficiency are close, every increase concentration a percent, apparent to the effect of aerification. ” Li Falin says, “The 3rd generation made oar technology solve industry of coal chemical industry to need to raise question of coal oar pH indicator considerably, enterprise of the chemical industry that it is coal enrages chemical art course in coal new space was extended on the choice. Enterprise of the chemical industry that it is coal enrages chemical art course in coal new space was extended on the choice..
According to not complete count, up to by 2016, dosage of oar of coal of water of our country fuel already broke through 30 million tons / year, domain of chemical industry of coal of; of combustion of the acting coal that basically is used at industrial boiler, acting oil, acting gas, furnace of aerification of water coal oar amounts to more than 300 to cover, the dosage of oar of aerification water coal achieves 120 million tons of above.
Economy of energy-saving environmental protection is strong
