Carry Over From Boiler Drum - Bright Hub Engineering

2020-12-23 · Carry over from drum can be of two types: mechanical carry over and vaporous carry over. The carryover from boiler drum results in deposits in the internal surface of superheater tubes leading to overheating failures. It also results in deposit in turbine blades which reduces the turbine efficiency. Mechanical carry over take place in a boiler mainly due to drum internals; drum level, foaming
