How Boilers Keep the Plants and Refineries Running Smoothly

Oct 28, 2013 · Additional Boiler Considerations. In order for a boiler to continue functioning safely and effectively there are several additional considerations to keep in mind. Water Level It is very important that the boilers normal operating water level (NOWL) be carefully maintained. If the water level drops too low it can cause boiler

Boiler Cycling Considerations - Babcock & Wilcox

Many fossil fuel-fired boilers are now experiencing load cycling or on/off cycling operation. These modes of operation involve cycling a unit on and off line or reducing loads to absolute minimums in response to varying load demand. This can be caused by daily or weekly load shifts experienced on nights and weekends, power generators dispatching units to the grid which utilize a lower cost

Improve Your Boilers Combustion Efficiency

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).

How To Optimize Your Condensing Boiler System For Maximum

Feb 08, 2019 · In summary, for optimal operation, condensing boiler systems need the return water temperatures well below the dew point of the boiler exhaust (for natural gas, this is around 140°F in the Bay Area and 125°F in Denver), ideally around 80°F or lower. Non-condensing boiler systems require the return water temperatures to be above the dew point
