Description

For making the burner of solid fuel gasification
Technical field
The present invention relates to a kind of for making the burner of solid fuel gasification.Described burner is particularly suited for using oxygen-containing gas to the carbonaceous fuel (solid fuel ground such as carried by carrier gas, the coal dust such as carried by the carrier gas of such as nitrogen and/or carbonic acid gas) gasification in use, such as, for generation of the synthetic gas pressurizeed, fuel gas or reducing gas.
Background technology
Reacted by fuel and oxygen and obtain the gasification of solid carbonaceous fuels.Fuel mainly comprises carbon as combustibleconstituents and hydrogen.Oxygen-containing gas and the carbonaceous fuel ground carried by gas enter into reactor with high relative velocity via the autonomous channel in burner.In the reactor, under keeping flame to be in higher than 1300 DEG C temperature condition, in described flame, fuel reacts with the oxygen in oxygen-containing gas, main formation carbon monoxide and hydrogen.
Propose multiple burner design scheme in the prior art.EP-A-328794 describes a kind of burner, and wherein, the centre channel that the coal ground is arranged via the longitudinal axis along burner is supplied to burner front portion, and oxygen-containing gas is via at least one circular channel supply around described centre channel.Oxygen is introduced in coal stream in burner front portion.
EP-A-130630 describes a kind of burner, wherein, anterior at burner, with at a high speed from center channels discharge oxygen-containing gas, and discharges oxygen-containing gas with low speed from ring exit.From the multiple outflow open discharge solid fuels between described center oxygen outlet and annular oxygen outlet.According to this open source literature, outside low velocity stream is used for preventing burner overheated because sucking hot gas.If this open source literature discloses burner for high-throughput, then preferably not there is annular shape for solid-fuelled outlet.Having set forth this design can not cause all solids fuel pellet suitably to contact with oxygen.
Dropped into business according to the burner types of EP-A-328794 to use howling success.But under high-throughput condition, the heat flux of leading to burner front portion increases to the value making to become too short the work-ing life of burner.
EP-A-130630 solves the problem of the heat flux of leading to burner front portion by applying low velocity barrier at flame periphery.Shortcoming according to the burner of EP-A-130630 is: for high-throughput, and solid fuel passes to burner front portion by autonomous channel, and this can cause etching problem.Another problem makes design complicated, and the described fact is the metalwork needing to manufacture many passages had for solid fuel and oxygen-containing gas.And because of synthesis gas/oxygen flame, the heat flux of leading to burner front portion may be still very high.
Summary of the invention
Following burner aims to provide for high-throughput and does not have the burner of the shortcoming of prior art burner:
A kind of for making the burner of solid fuel gasification, this burner comprises burner front portion, described burner front portion has for discharging solid-fuelled opening and the one or more openings for discharging oxygen-containing gas, wherein, for discharging solid-fuelled open fluid communication to centre channel, and wherein for the open fluid communication of discharging oxygen-containing gas to the circular channel being provided for oxygen and passing through; And
Wherein, centre channel has downstream part, wherein, the diameter of passage is cumulative on first paragraph, then end in burner front portion place second segment on decrescence, and wherein, hollow member is positioned with at the downstream inner of centre channel, described hollow member is positioned to it and closes an end and have opening at the anterior place of burner, described hollow member has corresponding with the cumulative of centre channel and diameter decrescence cumulative and diameter decrescence, solid-fuelled circular channel is used for be formed, this circular channel ends in burner front portion in the annular opening for discharging solid-fuelled inside sensing, and
Wherein, hollow member is communicated with the circular channel fluid for oxygen-containing gas by means of one or more connecting tube, and wherein, the opening of hollow member is formed for discharging the opening of oxygen-containing gas at least partially.
The invention still further relates to a kind of method by using said burner to make solid fuel gasification to prepare the mixture comprising hydrogen and carbon monoxide, wherein, oxygen-containing gas flows through the passage for oxygen-containing gas, and centre channel is flow through in solid fuel and carrier gas, and in the anterior generating gasification of burner.Detailed description of the present invention
