When the furnace was stopped without maintaining the pressure of steam,the steam space of the boiler will produce negative pressure and has air entrapment,so,the total steam valve should be opened first when we begin to ignite again.
The fouling of smoke tube leads to the rise of the exhaust temperature, so that the efficiency of gas steam boiler will reduce.Therefore,the cover of front and rear door should be opened regularly to brush or blow the fouling of smoke tube.
