Description
Technical field
The present invention relates to baker burner technical field, especially relate to a kind of low temperature diesel oil burner for gasification furnace baker.
Background technology
Can in coal gasification industry, startup burner be the core component in coal gasifier startup procedure, and can startup burner be lighted smoothly, be realize smoothly the key that coal gasifier is successfully driven.The conventional mode that adopts gaseous fuel and liquid fuel collocation to use of baker, such as liquefied gas baker+diesel oil baker, factory's fuel gas baker+diesel oil baker, direct factory fuel gas baker etc.
In gasification furnace baker process, need gasifier temperature progressively be raise in strict accordance with heating curve, and fusing point-18 ℃ of diesel oil, relative density 0.87-0.9, boiling point 282-338 ℃, 38 ℃ of flash-points, 257 ℃ of ignition temperatures.Physical property due to diesel oil itself, and the employing of baker burner is inversion type, diesel oil atomization particle is larger, therefore in coal gasifier the ignition temperature of diesel oil more than 500 ℃, and cannot ignite under baker initial stage low temperature environment, can not smooth combustion even if light, therefore coal gasification industry adopts diesel oil at low-temperature space as the direct baker of fuel at present or blank.
1, some company's gasification furnace baker flow process does not arrange natural gas and diesel pipeline, and the tail gas of directly producing with the said firm is as fuel, so gasification furnace production equipment needs regularly maintenance, in order to make normally to drive after gasification furnace maintenance, between turn(a)round, needing to utilize diesel oil that oven drying temperature is remained on more than 500 ℃.Suppose that turn(a)round is 26 days, diesel consumption is 250Kg/h, and diesel oil is according to 9000 yuan/ton of valuation, and between turn(a)round, single diesel consumption cost, up to 1,170,000 yuan, wastes energy and fuel cost.
2, existing gasification furnace adopts liquefied gas+diesel oil baker flow process, and liquefied gas large usage quantity, need arrange lng tanker as storage tank, but liquefied gas storage need to have the particular place layout of safe distance scope, and risk is higher, is unfavorable for application implementation.Therefore gasification furnace baker becomes the bottleneck of gasification furnace initial start-up and involuntary stoppage driving.
3, for the CO of our company baker, save the economic benefit of volume increase MDI, purify ice chest CO Design cooling load 17500Nm
3/ h, photochemical operation does not have the CO of surplus at full capacity time for our baker, and normal gasification furnace needs hot standby, the about 200-400Nm of baker CO consumption
3/ h, producing 1 ton of MDI needs 195Nm
3cO gas, calculate with 15 days, convert out the MDI that produces less 400 tons of left and right, monthly once, year underproduction MDI:4800t/y, according to 4000 yuan of MDI rates of gross profit/(ton MDI), can increase MDI annual earnings: 1,920 ten thousand yuan (turnover income).
