Description
Technical field
The present invention relates to the equipment of gasification of carbonaceous material, be specifically related to the vapourizing furnace of carbonaceous material slurry attitude (as coal water slurry, petroleum charred slurry, mud, waste liquid etc.) or powder attitude (as fine coal, solid waste, biomass etc.) charging.
Background technology
Gasification is that the coal cleaning transforms and the efficient leading core technology of utilizing, entrained flow bed gasification technology is used widely with its production intensity height, efficiency of carbon conversion height, environment amenable advantage, as production chemical product, IGCC generating, direct reduction iron making, Poly-generation, hydrogen manufacturing etc.In order to be complementary with its derived product demand and process characteristic, obtain maximum capacity usage ratio and economic return, water chilling-type vapourizing furnace and synthetic gas cooled vapourizing furnace have been proposed in succession.Representative water chilling-type vapourizing furnace is the coal slurry gasifier (ZL 94193847.6) of GE company and the multi-nozzle opposed type coal water slurry or the powder coal gasification furnace (ZL 98110616.1) of East China University of Science; What Shell company vapourizing furnace (ZL 90103807.5) then adopted is the circulation synthetic gas type of cooling.
When the synthetic gas after the gasification was used for IGCC generating or direct reduction iron making, the raising of synthetic gas temperature helped improving the efficiency of utilization of system.But if adopt water Quench mode that the high-temperature synthesis gas temperature is reduced to about 220 ℃ in this case, this obviously is uneconomic.For this reason, this patent has proposed a kind of novel vapourizing furnace that helps heat recuperation.
The vapourizing furnace of patent ZL 90103807.5 inventions is provided with a plurality of nozzles in its underpart, nozzle is in become the cut Small angle to install with the vapourizing furnace body of heater; High-temperature synthesis gas is discharged from vapourizing furnace top, and adds entry at 4～6 times of diameter places of distance outlet or gas cools off high-temperature synthesis gas.Its heat-eliminating medium is the cold cycle synthetic gas in the practical application.Its nozzle setting angle of the vapourizing furnace of this structure is difficult to accurate realization on engineering, installation deviation easily causes vapourizing furnace furnace wall scaling loss, influences vapourizing furnace work-ing life; It is long that heat-eliminating medium inlet that the said vapourizing furnace of patent upper end is provided with and high-temperature synthesis gas export distance, and the useful space of vapourizing furnace is increased, and the increase of heat transfer ratio surface-area causes production intensity reduction, thermosteresis to increase; The lime-ash that carries of high-temperature synthesis gas needs the natural temperature-fall period of one section longer distance on the other hand, and slag phase transformation after fixing in this process easily condenses in wall and makes that cross section of fluid channel is long-pending to be reduced, and the gas take-off rate improves, and the phenomenon of carrying scum silica frost secretly is even more serious.
The vapourizing furnace of patent ZL 01131780.9.5 invention, its underpart burner hearth is a horizontal type structure, is provided with a plurality of nozzles, vapourizing furnace top is the vertical cylindrical structure that has dwindled diameter.On the cylinder on vapourizing furnace top, spray into the secondary coal dust and go into stove,, outlet synthetic gas temperature is minimized by the gasification reaction of secondary coal dust.But because the residence time of secondary coal dust in vapourizing furnace that sprays into is too short, be in cryogenic reaction zone again, these coal dusts have little time to react completely and just are synthesized gas and carry and come out of the stove, and methane content rises and contains tar in the reaction product under the cold zone condition, will directly cause the quality of synthetic gas to descend.
