が多く、除塵効率の安定向上化が望まれていた。However, when the blending ratio of a plurality of fuels having different contained components greatly changes (especially when the fuel is switched), such as when co-firing coal and heavy oil, the dust particle size is changed. Since the distribution of Pd also greatly changes, the dust removal efficiency (collection efficiency) may fluctuate drastically. In such a case, it is often impossible to stabilize the dust removal efficiency simply by adjusting the flow rate of the exhaust gas, and it has been desired to stabilize and improve the dust removal efficiency.

低下する。(1) The relationship between the inlet wind speed u i and the limit particle size δ is expressed by an equation. δ = (18μrk 3 / ρ v k 4 2) 1/2 · 10 4 · u i -1/2 ... Here, mu: static viscosity coefficient of the gas (g / cm · S), r:
Radius of gyration (cm), ρ v : true particle density (g / cc), k
3 : constant determined by cyclone size, k 4 : constant determined by cyclone size. From the above equation, when the same cyclone and other operating conditions are the same, the limit particle size δ is inversely proportional to the square root of the inlet wind speed u i . For example, the inlet wind speed is 20 liters / min to 2 liters / m
When it becomes in, the limit particle size δ becomes 3.2 times, and the collection efficiency decreases. It can be considered that this is because the lowering of the wind speed lowers the inertial force of the dust in the introduced gas, which lowers the collision effect. Therefore, when sampling at a constant flow rate, the diameter a of the gas introduction pipe 5
The collection efficiency is improved by decreasing. But too much diameter a
If the value is too small, the pressure loss becomes large and the processing capacity decreases.

The relationship with and is expressed by an equation. log η 2 / log η 1 = (d 2 / d 1 ) 2 Here, η is the collection efficiency, and the relationship of δ∝d is established.
That is, the smaller the diameter d of the gas outlet pipe 7, the higher the collection efficiency. However, if the diameter d is made too small, the pressure loss becomes large and the processing capacity decreases.

Is expressed by an equation, and the relationship with the collection efficiency η is expressed by an equation. δ∝u r 1/2 / uθ∝ (L + H) 1/4 ... log η∝ (L + H) n / 4 ... where u r is an inward radial velocity, n is a particle size distribution index. Therefore, when the length L of the cylindrical portion 2 becomes large, the collection efficiency η slightly decreases.

Is expressed by an equation, and the relationship with the collection efficiency η is expressed by an equation. δαu r 1/2 / uθαD -1/4 ... logηαD -u / 4 ... the collection efficiency η as the diameter D is increased to a little improvement.

る。(5) In addition, regarding the influence of the size of the cyclone, δ∝r 1/2 and log η m / log η 1
There is a relation of = (m n ) 1/2 , and the collection efficiency decreases as the cyclone becomes larger. Here, m is a size ratio. Regarding the influence of the cone angle ξ,
The larger the cone angle ξ and the shorter the cone, the better the collection efficiency. However, since the conical surface may be worn, it is not preferable that the cone angle ξ is made as small as possible and the diameter d ′ of the dust collecting port is too small. On the other hand, the finer the particle size of the powder (dust) and the smaller the density, the lower the collection efficiency. Then, as the temperature rises, the limit particle diameter increases, and the collection efficiency decreases.
