Letting off steam about boiler water treatment

摘要

The humble packaged shell boiler is, arguably, the critical unit in the building when it comes to energy consumption and environmental pollution. Modern boilers use fuel efficiently and produce low emissions but if the resulting heat cannot be transferred into the boiler water efficiently, then the boiler will consume too much fuel, increasing both carbon footprint and operating costs. With heat transfer rates as high as 300kw/m2 any deposit on the water side of the heat transfer surface defeats the fire side efficiencies.
