Abstract
The invention discloses a three-channel slurry fuel gasification burner, which comprises an outer ring channel jet pipe, a middle ring channel jet pipe, a center channel jet pipe, an outer ring nozzle, a middle ring nozzle and a center nozzle that are coaxial. A slurry fuel enters a gasification furnace from a middle ring channel, and a gasification agent enters the gasification furnace from a center channel and an outer ring channel in two parts. The lateral sides of the center nozzle are provided with a lateral gasification agent jet orifice, along which the gasification agent can enter a middle ring channel from the center channel. The end face of the center nozzle is provided with an end face gasification agent jet orifice. At the center nozzle, the gasification agent is divided into a plurality of material flows, which are respectively jetted from the lateral gasification agent jet orifice and the end face gasification agent jet orifice of the center nozzle. The gasification agent jetted from the lateral gasification agent jet orifice contacts with the slurry fuel of the middle ring channel inside the head of the burner. And the slurry fuel also mixes with the gasification agent of the center channel and the outer ring channel at the outlet area of the burner, thus achieving a good atomization effect.
Description
Technical field
The present invention relates to the fuel slurry atomisation unit, especially a kind of triple channel fuel slurry gasification burner tip.
Background technology
The clean and effective utilization of carbonaceousfuels such as coal becomes the important topic of current energy utilization gradually.The fuel gasification preparing synthetic gas can be systems such as modern chemical industry production, combined cycle generation (being called for short the IGCC generating), ICL for Indirect Coal Liquefaction and coal hydrogen manufacturing the tap technology is provided.At present, the vaporizing system synthetic gas technology of carbonaceousfuels such as coal is divided into two types usually, and one type is the slurry gasification technology, and another kind is a dry powder solid gasification technology, and what existing domestic and international application was the widest is the slurry gasification technology.As one of key part that gasifies, the development of burner technology has directly determined the operation stability and the safety of slurry gasification technology, and the backwardness of burner technology has seriously restricted the raising of production efficiency.
Because the vapourizing furnace interior reaction temperature is up to 1400 ℃, the nozzle structure design is improper, its head of will ablating, and the ablation gasification stove internal wall produces serious consequence.When burner is abundant inadequately to the atomizing of fuel slurry,, reduce synthetic gas available gas component concentration with the efficiency of carbon conversion that influences fuel.When the burner head design is unreasonable, possibly cause the abrasion of burner top wall flooring, influence its work-ing life.It is the burner of straight pipe type structure that existing patented technology such as USP 4736693,4858538,4443228 and Chinese patent 89104265 etc. all adopt core jet pipe; The common shortcoming is that material lacked accelerator before spraying into reactor drum; The speed of leaving burner is low; Atomizing effect is not good enough, and is easy to the burner of ablating.The structure of employing pipe core front end reducings such as USP 3743606,3705108,4443230 improves logistics speed; Core jet pipe outlet logistics speed improves; The burner atomizing effect is strengthened, but speed will make the abrasion of burner head quicken after improving, and influence the work-ing life of nozzle.And for single nozzle overhead type vapourizing furnace, top jet nozzle outlet material flow velocity is crossed senior general directly influences the residence time of material in vapourizing furnace, thereby influences whole efficiency of carbon conversion.USP 6228224 adopts the four-way nozzle structure, with the atomizing effect of raising burner, but so will make nozzle structure complicated more, and the processing maintenance difficulties increases.In addition; Above-mentioned patent does not mostly adopt fire resistant wear prevention coating protection burner end face material at the burner section; Because more than temperature reaches up to 1400 ℃ near the burner spray orifice; Though adopted the end face water quench, be difficult to avoid the appearance of the bad working environments such as ablation and wearing and tearing of nozzle head.
In sum, solving problems such as the anti-wear and burner head cooling of high-efficient atomizing, the burner head of fuel slurry, is the key point that improves present burner use properties.Therefore, the advanced long lifetime high-efficient atomizing gasification burner tip of exploitation is one of gordian technique approach that improves China's fuel slurry gasification technology safety.
