止する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention discloses that the fluid and viscous gas produced during the gasification process contained in the product gas stream that flows upwardly toward a solid boundary and is then deflected at any of the fuel The present invention relates to a method for preventing ash particles from sticking.

方法でガス化過程の作動の経過に影響を与えてこれを乱
すおそれ一工ある。As is well known, in conventional O-bent pipes, stiction occurs before the generated gas containing fuel ash particles, which are either sticky or sticky, is deflected, and this causes an uncontrollable process during the gasification process. There is a risk of affecting and disrupting the process of operation.

とを目的とする。The present invention is directed to a solid boundary in which the product gas stream (including the fluid and/or viscous fuel ash components resulting from the gasification process is contained in the solid boundary OII salient zone KI!
The purpose of this study is to develop a method to avoid the occurrence of li1.

り以下で低下させることによって達成？れる。According to the present invention, the velocity of the produced gas stream as well as the fluid and/or viscous fuel ash particles contained therein reaches a hard boundary. This is achieved by reducing the settling velocity of any fuel ash particles below the value.

料灰粒子はその自重によって下方へ沈下し故に偏向した
のちに始めて固い境界に達する。According to this, the fluid and/or sticky fuel ash particles sink downwards under their own weight and thus reach a hard boundary only after being deflected.

の作動を糺すことはない。The sticking that occurs with the pair 9IIK according to the invention at a hard boundary outside the collision zone can preferably be removed by means of a hammer, so that it is not carried back into the gasification process and impairs its operation.

。Furthermore, tkfl&combination is achieved by reducing the velocity of the gas flow so as to flatten the temperature distribution of the product gas after deflection.

ス偏向装置から送出される。The fluidity and viscosity produced during gasification are determined by the high iIO product gas stream l that carries any of the fuel ash particles.
It flows upward from the lower blade at a constant speed in the direction of the boundary. The generated gas flow exits from the guide tube J into the space (
, whose velocity is the settling velocity yv of fluid and/or sticky fuel ash particles due to the expansion of the free flow cross-section,
Yoshi also decreases with low vh and v1o. As a result, the fuel ash particles, which are still fluid and sticky, sink downward IK and are carried outside the collision area S of the solid boundary by the deflected product gas flow and become stuck. It may be that this stuck gas is removed from the hard boundary by the striking tool 6, and the sloped surface is sent out from the gas deflection device by other means.
