Read MoreBoiler logs are the best method to assure a boiler is receiving the required attention and provide a continuous record of the boiler's operation, maintenance and testing. Because a boiler's operating conditions change slowly over time, a log is the best way to detect significant changes that may otherwise go unnoticed.

Read MoreThe Basics of Boiler Safety. The Basics of Boiler Safety. In 1905, the Grover Shoe Factory boiler exploded, collapsing the building and engulfing it in flames. Fifty-eight people were killed and 150 more injured. This event led to the development of safety laws and a national code for the safe operation of steam boilers.
Read MoreThe flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.
Read MoreBoiler water treatment is done to minimize corrosion, deposition, scale, and carryover in the water–steam circuits. The aim is to maximize the reliability of the steam–water circuit. Boiler water treatment has basically two phases: First, we remove impurities from the water to the desired cleanliness.
Read MoreBoiler banks transfer heat from flue gas to evaporate the steam–water mixture. A two-drum boiler bank was very typical in early boilers and is still used in smaller, low-pressure boilers. In small biomass BFB boilers one can often find a boiler bank (i.e., an evaporative heat transfer surface).
