Abstract
The invention discloses a micro-oil pure-oxygen enhanced plasma ignition method. The method comprises the following steps: when burning coal of a boiler is ignited, firstly a plasma flame generator generates plasma flame, burning oil is ejected around the plasma flame, and is pyrolyzed by the plasma flame to form a gas-phase mixture, and the content of hydrogen is about 90%; the gas-phase mixture is ignited by the plasma flame, simultaneously is matched with pure oxygen flow for combustion supporting, so that the formed flame torch is larger, the energy of the plasma flame is enhanced and meanwhile, the burning oil is saved; in the ignition process of the boiler, a large oil gun is not needed completely for combustion accompanying, and the ignition oil-saving rate of the smokeless coal boiler is increased to 85%-90%; and meanwhile, the low-load combustion-stabilizing capability is stronger, the oil can be saved by more than 90% when in low-load combustion stabilization, the combustion stabilizing purpose can be achieved even by using plasma and pure oxygen, and the burning oil is not used completely. The invention also discloses an igniter applied in the method.
Description
Technical field
The present invention relates to a kind of little oily pure oxygen of coal-burning boiler that is applicable to and strengthen the isoionic point ignition method, also relate to the igniter that uses in this method simultaneously.
Background technology
China is energy resource consumption big country, and the thermal power output of China accounts for 80% of national gross generation at present, and major part is the coal fired power generation unit; Be provided with coal-burning boiler; Coal-burning boiler is adopted traditional fuel ignition mode and low-load combustion-stabilizing, and annual igniting and stable combustion oil reach more than 1,000 ten thousand tons approximately.To the year two thousand twenty, estimate that China's coal fired power generation unit installed capacity will reach 600,000,000 KW, fuel consume also can increase sharply.Along with the continuous enhancing of China's economic development and national power, become the world's second largest oil consumption country that is only second to the U.S..Under this background, advocate energy conservation, carry out necessary fuel-economizing work and just have very important Special Significance.
China advocates the energy-conservation project that the Plasma Firing Technology and the tiny-oil ignition technology of station boiler are promoted as emphasis since 2000, to practice thrift a large amount of ignitions of the boiler with oil.Plasma Firing Technology is oily, only to utilize the technology of the direct firing coal-dust of plasma torch; The tiny-oil ignition technology be with a spot of fuel oil light the fraction coal dust, again utilize the coal dust burnt light more coal dust, with the firing technique of powder for oil.
The pulverized-coal fired boiler Plasma Firing Technology of China grows up through technology transfer, absorption, improvement, raising during the nearly last ten years, is the technology with independent intellectual property right and technical characteristic.In technology popularization and commercial Application, obtained many gratifying oil-saving effects, but simultaneously also exposed gradually should technology weak point.A large amount of commercial Application facts have proved; It is consistent that existing plasma technology can be lighted the conclusion of " pyrolysis under plasma condition of the bituminous coal of volatile matter 25%-40%, gasification result better " that volatile matter draws greater than 25% high-quality bituminous coal and some experimental studies smoothly.But existing plasma technology is still undesirable for the igniting effect of high moisture content brown coal, meager coal, also needs big oil gun companion combustion, and oil-saving effect is greatly affected; Plasma ignition for anthracite-fired boiler does not more have ripe commercial Application case at present.
The tiny-oil ignition technology is the native country technology of growing up in China, and the tiny-oil ignition technology is to go deep into the inner firing technique of airduct one time, is the further deeply development of small oil gun few-oil ignition technology in China's primary air nozzle of the nineties in 20th century.Utilization tiny-oil ignition technology is carried out the igniting and the low-load combustion-stabilizing of bituminous coal fired boiler, all ripe grasp of domestic many igniting companies.But the firing technique for the meager coal boiler is still immature, says with regard to the whole country, and the tiny-oil ignition technology for anthracite-fired boiler still is in the desk study stage at present.
The shortcoming of existing Plasma Firing Technology shows through the commercial Application practice; Except the electrode material life-span fall short of, cost is higher, the less reliable; Topmost shortcoming is that ignition energy is not enough, coal adaptability is poor, needs big oil gun to accompany problems such as combustion, can not light low volatile coal and anthracite.
At present, domestic plasma igniter power is mostly at 150KW, and minority is 250KW, and the AC plasma igniter can reach 300KW but commercial Application is still immature.Because power is little, can not satisfy the requirement of lighting low volatile coal and anthracite-fired boiler.
For existing Plasma Firing Technology; No matter be direct current plasma technology or AC plasma technology; Increase ignition energy and igniting power, need to increase rectification or power transformation ability, ability to transmit electricity, add large electrode etc., not only cost further strengthens; Installing space also can strengthen, and some technical bottlenecks are still difficult in a short time to be broken through.
