How to avoid the fouling of gas hot water boiler
Gas fired hot water boiler,as one kind of environmental protection industrial boiler,gets gradually the favor of market and people because of the more strict national environmental standards.However,after the long run,serious fouling will form,which increases the operation cost of gas fired hot water boiler,some ways can be adopted to avoid the fouling,they are in the following sections.
In the long operation of gas-fired hot water boiler,regular soot blowing is necessary,after the shutdown,regular cleaning of the fouling is also needed.
Choose the reasonable return water temperature according to furnace profile and fuel type,generally,the return water temperature not lower than 60℃.
When the fouling is removing,the flow direction of flue gas and water adopts the parallel,downstream mode.
In order to facilitate the flushing fouling,the velocity of flue gas of gas fired hot water boiler can be improved appropriately to increase the convective heat transfer,at the same time, flue gas stagnation region should be reduced,and the cold water pipe try not to be arranged here.
The gas fired hot water boiler of Zhengzhou Boiler Co., Ltd,has won the high praise from customers at home and abroad because of its advanced processing technology,strict quality control and long service life,if you want to know more about it,do not hesitate to blowse its webpage.
