What affects the soot blowing frequency of chain grate boiler

2016-05-13

In industrial production,coal fired boiler has another name,that is,chain grate boiler,in the operation of chain grate boiler,the soot blowing is needed to avoid the fouling on heating surface.Zhengzhou Boiler Co., Ltd.,an experienced industrial boiler manufacturer in China,gives the factors affecting the frequency of soot blowing for your reference in the following sections.

Generally,the frequency of soot blowing in the operation of chain grate boiler is decided by the type of coal ash and the temperature of flue gas form the air preheater.The rise of exhaust gas temperature indicates the convection heating surface has too much fouling,the soot blowing is needed.The traveling grate boilers of Zhengzhou Boiler Co., Ltd.,has designed the push-pull type gate soot cleaning device,the gate adopts the heat-resistant cast iron finishing seal structure,which prevents the deformation of secondary combustion and the air leakage of grate effectively.

The carbon monoxide emissions also can be used as an auxiliary criterion to decide the frequency of soot blowing ,especially,when the coal of poor activity is fired,the fouling contributes to the gasification of flying ash containing carbon on the tube wall,which increases the emission of carbon monoxide.The operating personnel must be familiar with the characteristics of coal,and weigh the soot blowing cost and the improvement of boiler efficiency.

The traveling grate boilers of Zhengzhou Boiler Co., Ltd.,is advantageous to the combustion of inferior coal and can adapt to wind coal types, which have won the high praise form customers at home and aboard,if you need a coal fired boiler or related consulting,please feel free to contact us!
