Boiler Aging

Boiler Aging

boiler aging: Like humans, even Steam Boiler ages with time. And it is essential for one to be aware of the changes that Boiler goes through with time. The life cycle of Steam Boiler components is governed by the magnitude of stress, variation in operating parameters, chemical regime during its service life and suitability of materials to sustain those conditions.

IBR Regulation – 391 A

As per IBR Regulation – 391 A, the permissible limits of pressure, creep existence etc. according to the time of operation; have been mentioned for both the smoke tube and water tube boilers. It has been experienced that, there is the considerable gap between the actual need for a particular industry and selection of industrial boilers.

Boiler designing here plays a vital role as the calorific values are also different from the fuels, one for which the boiler is designed and the other on which the boiler is actually operating. Fluctuations in the steam requirements as per the industrial process also compound up to the aging process. As the heat release rates vary accordingly with the requirements, so does the thermal stress cycle produced in the Boiler. Proper Boiler selection by the end user and Flexible working capability of the Boiler as per the calorific values by the design engineer are the areas of paramount importance.

IBR Regulation – 626

Another area of great concern in Steam Boiler Aging is the Water Chemistry. The water being fed for steam generation must be treated accordingly to be maintained within the permissible limits as per IBR Regulation-626, based on the working pressure of the Steam Boiler. Poor quality of water causes erosion (removal of exposed material with time), corrosion (destruction of chemically affected material through oxidation), scaling (reduced heat transfer with time). Installation of De-Mineralization /Reverse osmosis plant comes in handy when tackling this problem.

At Thermodyne, we have successfully installed and commissioned numerous DM/RO/Water Softening Plants to our esteemed clients.
