How to correctly use the horizontal coal-fired boiler
Compared with the vertical boilers, horizontal coal fired boilers have obvious advantages in energy conservation because of long flue gas flow,slow speed of smoke exhaust and high thermal efficiency.Like other industrial boilers, the service life of horizontal coal fired boiler is closely related to its use and maintenance,the correct ways of using horizontal coal fired boiler will be introduced in the following sections.
The coal property requirement of horizontal coal fired boiler
The most suitable coal of horizontal coal fired boiler has weakly caking,moderate size,more than 15% volatile component,more than 1250℃ ash melting point,and more than18800~21000kJ/kg calorific value.
The ignition cautions of horizontal coal fired boiler
Open the ash door during ignition,then add a small amount of coal.During normal combustion,coal storage tank should be filled with coal,feeding door and ash door should be closed,and the wind door should be opened appropriately.At the same time,before ignition,no pipeline freezing should be ensured to prevent accidents.
The inner cleaning of horizontal coal fired boiler
Horizontal coal fired boiler needs regular cleaning,as well as gas pass,when cleaning gas pass,the flue door and dust removing door should be opened. The water supply requirement of horizontal coal fired boiler
Before ignition,fill water tank and pipe should be filled with water,half water tank is filled with water,adding water after ignition is prohibited,the operation in the condition of no water,water shortage and unclear water quality is prohibited.
The horizontal coal fired boilers of Zhengzhou Boiler Co., Ltd,lengthen the furnace front rear axle,extending the combustion time of fuel in the furnace,reducing the carbon content in slag,increasing the effective area of the grate and the overload capacity of horizontal coal fired boiler.The relentless pursuit and exploration of industrial boiler has won high paise form customers at home and abroad,Warmly welcome to understand and consultation of our products!
