Abstract
This invention relates to a burning device and process of petroleum coke water slurry which is applicable for industrial boiler and furnace using the petroleum coke water slurry as fuel. In this burning device the boiler body has the multiply positioned inlet of the straight flow triple fuel burner in which each array includes the independent inlet, the inlet adaptable for refinery off-gas lance and the inlet adaptable for slurry and oil lance, and each level has identical inlets. The burning process uses petroleum coke water slurry as the primary fuel and refinery off-gas, fuel oil as assistant fuel, it first combusts refinery off-gas, petroleum residual slurry or fuel oil to raise the temperature of the combustion chamber to 680-700deg.C and the boiler load to 60-70%, and then switches to petroleum coke water slurry gradually.
Description
Technical field
The present invention relates to a kind of burner and combustion method thereof, particularly relate to a kind of Industrial Boiler of burning petroleum water coke slurry fuel that is applicable to and use, also can be used for the petroleum water coke slurry combustion apparatus and the combustion method thereof of industrial furnace.
Background technology
In recent years, a large amount of Industrial Boilers or industrial furnace equipment are because of must the control exhaust pollution using the less what is called " clean fuel " of burning back discharging waste gas pollution such as heavy oil, natural gas or coal gas instead, cause the demand of these energy increasing thus, and these natural energy resources are fewer and feweri, price is subjected to the soaring influence of international oil price also more and more higher, making the cost of combustion of industrial boiler this type of " clean fuel " rise significantly, is that the Thermal Power Station of fuel is in general lossing state with heavy oil, residual oil particularly.And adopt the discarded petroleum coke of factory of oil refinery, oil refining waste gas to carry out twice laid, and both can reach the purpose that reduces cost and save energy and reduce the cost as station boiler fuel, meet the environmental protection policy of national energy-saving and emission-reduction again.At present, the burnt slurry of water, oil refining waste gas replace heavy oil, coal tar or natural gas etc. not to appear in the newspapers as yet for fuel uses on station boiler.The high sulfur petroleum coke that the applicant adopts petroleum refining process to produce carries out twice laid, research and develop out a kind of can wide popularization and application in petroleum water coke slurry fuel and the prescription and the process for making of Industrial Boiler, high sulfur petroleum coke through break process, and is added the clean fuel that an amount of water and chemical addition agent are made a kind of high heating value, low ash content, low sulfur amount.Petroleum water coke slurry is with a wide range of applications as the New-type fuel of a kind of alternative oil, coal.This fuel not only raw material sources is wide, cheap, and use this fuel can also reduce the petroleum coke of stacking as waste residue because of PETROLEUM PROCESSING enterprise to take the large tracts of land soil, and in the petroleum coke dust, petroleum coke based on sulphur etc. the release of harmful substance and the environmental pollution that causes.Use this petroleum water coke slurry fuel, can rationally utilize natural resources, can reduce the fuel cost of Industrial Boiler equipment again, simultaneously can also be by the back discharged flue gas of burning being carried out environmental protection treatment to reduce environmental pollution and to reclaim the raw material of industry, more meet country and save petroleum resources, improve the energy policy of resource circulation utilization rate.Oil refining waste gas is after oil plant is processed crude oil, to obtain the byproduct that a series of chemical products obtain simultaneously, mainly makes some low-carbon (LC) hydrocarbon gas.Because of reutilization technology is that a few countries such as Japan, Germany are grasped at present, the cost recovery of oil refining waste gas is very big, and therefore general oil plant does not reclaim, but will be discharged in the atmosphere after its burning.Not only waste the energy, but also can cause atmosphere pollution.But because petroleum water coke slurry viscosity is big, easy precipitation, its fugitive constituent is about 11.3%, and water content is about 30%, has the difficulty of catching fire, easily coking, easy problems such as dust stratification, difficult after-flame during burning, and it catches fire, surely difficulty of combustion is all big than water-coal-slurry.Therefore this just needs a kind of burner and combustion method thereof that can use petroleum water coke slurry stably, reliably.
China utility model patent ZL200520102406.7 disclosed " hexagonal is arranged direct current water-coal-slurry, heavy oil dual burner " (Granted publication number: CN 2800082Y; July 26 2006 Granted publication day), this patented technology obviously can't be suitable for the requirement of burning petroleum water coke slurry.
Chinese invention patent application 200610071211.X discloses " process that the burnt slurry of water uses " (publication number: CN 1935712A on glass melting furnace, open day: on March 28th, 2007), this patented technology is had relatively high expectations because of preheat temperature, and main fuel is too single, the combustion-supporting fuel of the use fuel oil of also just having to highly rely on.
Chinese invention patent ZL03113078.X discloses " water burnt slurry cyclone burner and method " (Granted publication number: CN 1181287C; Granted publication day: on December 22nd, 2004), this device is made up of spray gun, combustion chamber, tangential wind inlet, the burnt slurry of water spray gun is located at an end of whirlwind tube combustion chamber, once tangential wind inlet, the tangential wind inlet of secondary are set in sequence on the wall of whirlwind tube combustion chamber in the burnt slurry of water spray gun downstream, whirlwind tube combustion chamber temperature is more than 900 ℃, the wind rate 30%-50% of once tangential wind, the wind rate 70%-50% of the tangential wind of secondary, wind speed is 20m/s-100m/s.This burner exists the temperature requirement that catches fire higher in actual applications, and the fuel range of choice is narrow, and igniting is difficult, and than problems such as easy cokings.
