Application of ventilator in industrial boiler
Industrial boiler consist of feeding system,combustion system,soot blowing system,air supply system and automatic control system,as a link of the combustion process,air supply system plays an important role in the combustion of fuel,ventilator is the main part of equipments used to ventilate.
As an important auxiliary equipment,ventilator is chose on the basis of the type, specification, use and property of boiler,only the matching ventilator is chose,can its effectiveness be optimized. Then,let’s discuss the ventilator application in industrial boiler.
According to the type,to ensure the temperature uniformity in furnace,we can choose the circulation ventilator,considering the requirements of high temperature resistance and creep deformation of impellers contacting hot air ,generally,the ventilator use the materials containing molybdenum or nickel,use heat insulating material or hollow shaft cooling water to cool the bearings and use the structure having no shell.
According to the occasion,when we have two or more options,the ventilator of high efficiency,smaller volume and larger adjustment range is prior,of course ,the decision should be made after weighting the advantages and disadvantages.
According to the requirement of noise elimination,we should firstly choose the ventilator of high efficiency and low impeller rotational speed.at the same time,noise elimination and damping measures should be adopted.
Ventilator is widely used in various industrial boilers,to enhance the efficiency of the industrial boiler,we must have a good knowledge of the ventilator application,as a professional manufacturer of industrial boilers,Zhengzhou boiler will give us more effective suggestion about this.
