Description
Technical field
The present invention relates to the liquid fuel gasification burner, especially a kind of load controllable multi-pass road liquid fuel gasification burner.
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 liquid fuel gasification technology, and another kind is the dry-powder solid fuel gasification technology.As one of key part that gasifies, the development of burner technology has directly determined the operation stability and the safety of liquid fuel 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 the fuel atomizing of burner liquid towards is abundant inadequately,, 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.In addition, the evaporation efficiency of burner head cooling system directly influences the LP reliability service of burner.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, and the gasification burner tip that it adopted can't carry out load control usually.
In addition; The liquid fuel gasification burner of existing industrial application all adopts the simple relatively coil tube type water-cooling system of manufacture craft basically; Like Chinese patent 95111750.5 and 200710037138.9 etc., it mainly exists head cooling jacket structure design simple, the problem that cooling performance is not good.And adopting the triple channel structure design, the load control ability is relatively poor, during particularly to integrated gasification combined cycle for power generation, can't adapt to the electrical network peak change by flexible gasification load.
In sum, problems such as the high-efficient atomizing of solution liquid fuel and the cooling of burner head are the key points that improves present liquid fuel gasification burner use properties.Therefore, the advanced load controllable type long lifetime high-efficient atomizing gasification burner tip of exploitation is one of gordian technique approach that improves China's liquid fuel gasification engineering reliability.
