What should we do before starting a hot water boiler
Hot water boiler,as one kind of motivity equipment of heat energy,is widely used in hotels,schools,communities,enterprises,public institutions,etc.Therefore,the hot water boiler system's operational safety appears to be of particular importance,before starting it,we have many preparations to do,they can be summed up as follows:
The external inspection of hot water boiler
We should ensure that the insulation of furnace wall and other parts is good,supports and hangers are intact and firm,long soot blower is in the exit position,flue gas temperature probe and various parts expansion indicators is intact and correct,lighting is good,fire equipments is complete,and so on.
The internal checking of hot water boiler
We should check the combustor,gas pass,electrostatic precipitators,superheater, reheater,economizer, preheater, cold slag bucket, milling system,and other parts to ensure that nobody is working inside,no tools are left behind,no sundries on heating surface,scaffolding is removed,no fouling and slagging in cold ash bucket,no sundries in slag conveyor and slag warehouse.
The external inspection of hot water boiler preheater
We should ensure that the appearance of preheater is complete,driving and variable speed device is good,oil level of various parts is normal,sealing device is good,pipeline valves are complete,have no leakage,the cooling water of bearing box is normal.
Checking the combustion system of hot water boiler
We should ensure that the thermal insulating of burner is good,no fouling is on the air duct and bellows,oil gun, igniter and electromagnetic valve are intact and good,oil gun and igniter are in the exit position.
Meanwhile,Zhengzhou Boiler Co.,Ltd,as a famous industrial boiler manufacturer in China,also indicates that we should check the steam,water and oil system of industrial hot water boiler to ensure that all security doors and pressure gages are intact and good,drum local water level meter is complete and clear,etc.
The industrial hot water boilers of Zhengzhou Boiler Co., Ltd have the defensive functions of over-temperature,overpressure,water shortage,flameout,and leakage detecting.Pleasure feel free to contact us for more details,best products and service shall always be provided here!
