Typically, if there’s a problem with a modular boiler, it’s confined to one of the tubes, meaning the boiler isn’t at risk for a massive explosion, which is rare but possible with conventional boilers.
Chat OnlineWhen this boiler water carryover is excessive, steam-carried solids produce turbine blade deposits. The accumulations have a composition similar to that of the dissolved solids in the boiler water. Priming is common cause of high levels of boiler water carryover. These conditions often lead to super heater tube failures as well.
Chat Onlinenot need high maintenance, boiler tube, add-on devices if the boiler is designed for optimum flue gas velocities in the first place. Each boiler pass should be designed with a cross sectional area to achieve optimal flue gas velocity, which in turn maximizes heat transfer while also minimizing performance robbing soot build-up within the tubes.
