Industrial steam engineering across Bangladesh
Notes
Sizing, inspection, water treatment and fuel notes from the engineers who install and service steam boilers across Bangladesh.
Nameplate figures do not size a boiler. Measure peak against average steam demand in kg/hr, fix the working pressure and count the condensate you get back, then pick the capacity from those three numbers.
Read the noteGroundwater across the delta carries high calcium and magnesium hardness plus dissolved oxygen. Untreated, it scales tubes within months, drives fuel consumption up and eventually splits the metal. Here is the treatment that prevents it.
Every steam boiler in Bangladesh needs an annual certificate from the Office of the Chief Inspector of Boilers. Here is what the inspection covers, how to prepare the plant and what stops a certificate being issued.
