  • Frequency Converter energy savings on Boilers

    Boilers and heaters account for a significant share of a plant's purchased fuel cost. Combustion air fans are necessary to provide enough combustion air to the boiler or heater's burner system. Louvers, inlet guide vanes or frequency converters control the amount of air allowed into a boiler. Configuring a combustion air fan to allow the proper amount of air into the burner can improve boiler ...


  • Tuning Your Boiler for EPA Boiler MACT Compliance

    The EPA’s Boiler MACT regulations are heating up. Boiler MACT is an EPA rule to limit hazardous air pollutants (HAP) from commercial and industrial boilers and process heaters. Originally proposed in 2011 as a mandate driven by the Clean Air Act,  the rules are Area Source Boiler MACT 40 CFR 63, subpart JJJJJJ for smaller boilers (stores, hotels, apartments, ...

  • Saving waste in the boiler house

    Burner technology has improved greatly in recent years. Older Burners had a series of cams and levers that were calibrated to provide specific amounts of air for a particular rate of firing. Being mechanical items, these wore and sometimes required calibration. They, therefore, had to be regularly serviced and calibrated. Generally, new burners use frequency controlled motors and cams to open air ...

  • Rectify dry cycling of gas boilers and reduce energy costs by 25%

    Building engineers, energy and facilities managers tend to overlook that many gas boilers waste energy through dry cycling when they are not actively contributing to the building heating and hot water demand. It is often thought that existing building management systems (BMS) and building energy management systems (BEMS) are optimising the boilers to remove dry cycling. However, the BMS is ...

  • Energy, exergy, thermoeconomic and sustainability analyses of a building heating system with a combi–boiler

    The energy, exergy, thermoeconomic and sustainability analyses are applied to the building heating system with a natural gas–fired combi–boiler. The building area is considered as 90 m². Furthermore, the design and analysis of the natural gas installation of the building are done. Two different methodologies (Fine–HVAC and LowEx analyses) are used for energy analyses (heat loss and demand) of the ...

  • Experience on coal reburn in a utility boiler

    Reburning is an in-furnace combustion modification technology for the reduction of NOx. By staging the introduction of the fuel, an environment is created where NOx generated by the combustion of the main fuel supply is subsequently consumed by the hydrocarbon radicals arising from the reburn fuel under reducing conditions. ENEL has retrofitted unit No. 4 of Vado ...

  • Monitoring flammable gas in boiler houses

    The most common fuels in use for space and water heating are Oil, Natural Gas and Liquid Petroleum Gas (LPG). By far the most popular, clean and cost effective solutions are utilising Natural Gas or LPG. The traditional safety measure derived from the time of oil fired boiler houses is the use of a fusible link placed above the each boiler. The fusible link is intended to melt if it becomes ...

  • Chemically Inclined: The Case for Clean Boilers

    Boiler cleaning is something most companies don’t want to think about — if boilers are working within operational limits it’s often easier to keep up with smaller preventative maintenance (PM) tasks but put off a total chemical clean ...

  • Cumulative exergetic assessment of LPFO utilised steam boilers

    This paper relates to a study on the energy and exergy resources, transfers, consumption and losses in the combustion and heat exchanging units of industrial steam boilers. Mass, energy and exergy analyses, which included the physical and chemical exergies of material streams, were used to investigate the energy resource utilisation of Low Pour Fuel Oil (LPFO) in industrial steam boilers. The ...
