Roots Blower Used in Power Industry Flue Gas Desulfurization Plant
Product Introduction
The performance tables provide the blower's model number, bore,
rotational speed (r.p.m), discharge pressure, air capacity, and
required power.
The air capacity in the tables is indicated in the standard suction
state.The standard suction state herein mentioned is defined as the
condition at 20℃ temperature, 1.0332Kgf/cm2 (101.3KPa) absolute pressure and 65% relative humidity.
The reference air capacity (temperature 0℃ and 1.0332kgf/cm2 (101.3kpa) absolute pressure) is generally indicated in Nm3/min.
However, it may be converted into the standard air capacity by the
following equation, if the suction pressure is equal.
Qs = QNx1.0732
Where, Qs: standard air capacity (m3/min); and
QN: reference air capacity (m3/min).
The discharge air capacity can be converted into the standard air
capacity by the following equation.
Qs = Qdx (1.0332+Pd)/ 1.0332x(273+Ts)/(273 + Td)
Where, Qd : discharge air capacity, in m3/min;
Pd : discharge pressure, in Kgf/cm2,
Ts : suction temperature, in ℃,
Td : discharge temperature, in ℃.
Based on the air capacity and discharge pressure calculated as
above, the performance table lists the model, bore, r.p.m., and
required power.
