Technical Papers. Since the inception of our company in 1976, JANSEN employees have authored numerous technical papers and publications pertaining to biomass, chemical recovery, and MSW/RDF boiler topics. These papers were presented at technical conferences, such as TAPPI, ICRC, BLRBAC, INFUB, NAWTEC, NCASI, as well as other venues.
All boilers designed and manufactured for steam production have several factors in common. Regardless of whether the boiler is a firetube or watertube design, it is important to evaluate key factors that will influence the operational efficiency of the equipment and impact its return on investment.
A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam. The paper presents
The general audit alternatively called a mini-audit, site energy audit or complete site energy audit expands on the preliminary audit described above by collecting more detailed information about facility operation and performing a more detailed evaluation of energy conservation measures identified.
The smaller temperature difference, or ΔT, reduces the load on the gas boilers, decreasing the firing rate and cutting gas consumption. However, the rise in return water from 40°C to 43.3°C will also affect the boilers’ condensing operation, lowering overall boiler efficiency by approximately 2% as shown in Figure 3.
Boiler operation is complicated, especially for modern boilers that are fully automatic. Safety, efficiency, and constant generation of steam or hot water depend on the smooth operation of the boiler. Moreover, some jurisdictions have laws and rules on the boiler operation and boiler operators.
Boiler 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.
The operation performance of circulating fluidized bed combustion (CFBC) boiler was studied in this paper. The experimental results indicate that the load of CFB boiler has linear relation with bed temperature and bed material height of operation.

July 2006 ASHRAE Journal 51 Boiler System Efﬁ ciency By Thomas H. Durkin, P.E., Member ASHRAE About the Author Thomas H. Durkin, P.E., is director of engi-neering at Veazey Parrott Durkin & Shoulders in Indianapolis. When natural gas cost $0.40 per therm* (1999), even a poorly designed boiler system would have positive payback.
Investigating the Impact of Boiler Aging In Replacement Decisions Siddika Pasi and Michael R. Muller, Rutgers University - Center for Advanced Energy Systems ABSTRACT Traditionally boilers were believed to operate efficiently for fifteen to twenty years at the end of which they are typically replaced.
