May 02, 2016· It is a simple fire tube boiler which has multiple fire tubes. These tubes increase the heat transfer area of boiler. Water passes over the tubes. The heat is transfer from fire tubes to water through convection. Working of Cochran boiler: Cochran boiler works as same like other fire tube boilers. It can be understand by following points.
Steam boilers provide efficient heat for homes and industrial settings. In most cases, raw water is fed into the boiler from a pipe system. That water is then purified to clean it of any debris. Next, the water is fed into a de-aerator that removes air, then is fed into the boiler tank and heated.
Water tube boilers also include a downcomer tube that connects the steam drum at the top of the boiler with the feed water drum that sits at the bottom of the boiler. Some of the steam created from the boiling water will inevitably cool and condense back into water that will then travel through the downcomer tube back to the feed water drum.

Retubing & tube replacement for boilers of all sizes. IB&M specializes in the retubing of firetube boilers, watertube boilers, superheaters, pre-heaters, heat exchangers and other pressure vessels. Boiler tubes must be able to endure extremely high temperatures, pressures, and potentially wide fluctuations in demand depending on the application.
Extend the life of your boiler: Tubes are the heart of any boiler unit. Improper deaeration and water treatment can significantly affect the lifespan of tubes. Additionally, tube replacement can often indicate water quality issues that need to be addressed. Retubing can increase the life of the unit by many years.
