How to prolong chain grate boiler operating life 
How to prolong the chain grate boiler operating life
The longer service life of chain grate boiler can reduce investment costs,accord with the requirement of national energy saving at the same time,in addition to the requirements of maintaining a relatively stable furnace conditions by avoiding stopping,decreasing,and increasing the wind frequently,we also should take the following measures to prolong the operating life of the chain grate boiler.
Masonry stove operation:masonry quality has a significant impact on the chain boiler furnace life, there should be someone to check ramming knot density.Refractory brick masonry cracks should be less than 1 mm,and mortar joint mud should be full to prevent drilling iron.Furnace bottom of the cylinder adopting the aluminum carbon bricks adding plastic and carbon ramming material can effectively slow down the bottom erosion,especially after adopting the dry hearth and pressure eliminating slag process,the furnace service life has been greatly improved.
Strengthening the furnace blow-in operation:according to the stipulated time and temperature to warm the furnace,add the batch of material after the bottom coke pass the fully burning,after adding the iron material,damping down for 30min to preheat the furnace burden thoroughly,and strictly control the bottom coke height at about 2000 mm,make sure to see the iron drops at about 30min after the air supply,supply air strength shall be controlled in a certain range according to the production requirements of melting rate,the initial re-open of furnace should not blindly use large air volume.
The above is the simply analysis about prolonging the operating life of chain grate boiler,we still have many to do to achieve that.ZG chain grate boilers has been hailed as the best design solution,has the world advanced level,pleasure feel free to contact us for more details!
