Atmospheric Condenser Boiler　FO　Supply　Pump Supplies FO or DO from each service tank to FO burning pump. Forced　Draft　Fan Supplies air for combustion, pre­purge and post­purge on aux. boiler Soot　Blower Operation for Removing the soot attached on the heating tubes of aux. boiler or exh. gas economizer with steam. It has done in periodically to keep the thermal efficiency and prevention of getting damage of heating tubes. Inspection　Tank Inspects the oil incorporation into the drain from　heating steam drain. So called as Observation tank too. Feed　Filter　Tank Removes the oil and impurity materials from condensate water (boiler feed water). Atmospheric　Condenser As a role , condensation the steam drain from the tank-heating line and several heaters with low temp cooling fresh water. 2019/2/19 ボイラ

About the important word・・・ ・PREPURGE This operation is for ventilation before the ignition to prevent a backfire . ・POSTPURGE This operation is for ventilation after the extinction to remove the remaining gas inside the combustion chamber. This operation prevent the corrosion . 2019/2/19 ボイラ

Necessary for BLR water Analysis and treatment ・prevention of sticking the scale When the scale stick on the tube , the place will be superheated. Finally , scale will bring the trouble(burst and crack…).Beside of that, it will be source of decreasing the thermal efficiency. ・prevention of corrosion The place where exposed with boiler water gets the corrotion with efficiency of ionize. ・prevention of carry-over Phenomenon of bringing out the boiler water with steam. It’s will be a source of decreasing the thermal efficiency and corrosion because of impurities inside the boiler water. 2019/2/19 ボイラ

Burner Maintenance To keep a good combustion , we have a maintenance in regularly . Above all,the accumlation of the carbon around the igniter and pilot burner invite the bad ignition. When the carbon stick around the swirler,it retard the ventilation.
