The operational aspects of forced draft fans of boiler are analyzed and its modification plan based onthe working principle of hydraulic pressure coupler with speed control is briefly introduced in this paper.

This analyzes looks for processe of 1 175t/h boiler forced draft fan surging much times, through analysis finds forced draft fan surging of reason and preventive measures, for other power company have definite reference value.

Prior to engaging an air velocity measuring device at a boiler s forced draft fan s exit manifold, it s volume flow and its pressure differential have both to be calibrated to provide quantitively accurate correction factors for compensating differences between instrument readings and actual magnitudes.

There are no existing design criteria for primary fan and blower volume and pressure head design margins.

type A-B1557 medium voltage transducer for blower control in Huangshi power plant,the principle and feature of frequency conversion and the expected operation result in blower control are introduced.

Based on the analysis of main noise source,frequency spectrum and noise characteristic of the forced draught blower, using the control theory of the noise, we have designed and implemented the noise control scheme and reached the anticipated result.

Disquisition of Condition-Based Maintenance System of Air Feeder in Power Plant Based on ANN;

Application of SIEMENS MV series frequency converter in feed fan;

On the basis of the cause analysis on RB test failure for 200 MW Middle Store Powder Manufacturing System,against the existing problems,this paper introduces some adjustment measures from the aspects of adjusting feed fan parameters,setting maximum speed,regulating power error.

Anti-surge control of air blower for reaction tower;

This paper is based on the similar theory and described two kinds of the studying method in performance of air blower when it is transformed to the draw blower.
