  • 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 ...


  • Energy recovery from biogas purification

    Energy recovery from biogas is becoming more common, but the processes are hampered with the presence of hydrogen sulfide (H2S). Biogas is a mixture of methane and carbon dioxide (CO2) and is often contaminated with toxic quantities of H2S. Sources of biogas are: municipal landfills that produce landfill gas (LFG), wastewater treatment plants, industrial plants, and large scale livestock farms. ...

  • Case study - Oxidizer energy recovery options

    Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and ...

  • 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 ...

  • Energy Recovery from Residual Waste by Means of Anaerobic Digestion Technologies

    ABSTRACT Anaerobic digestion (AD) is a natural process, spontaneously taking place in natural surroundings, such as marshes,bogs, paddies, or in cesspits, landfills, and dedicated digesters, used for the conversion of organic waste into a rich gas. Typical AD substrates are: manure, sewage sludge, high BOD wastewater, and – more recently - the organic fraction of Municipal Solid Waste (MSW), ...

  • Heat recovery and energy efficiency, improves profitability and reduces CO footprint

    Using latest technology in combustion of oil and gas can provide significant savings in overall energy consumption. Modern oxygen control that compensates changes in ambient temperature and fuel qualities can increase energy efficiency up to 3%. By adding the usage of hot combustion air another 2-3% can be saved. Modern burner technology without mechanical linkage, operating with accurate ...

  • Assessing Feasibility of Direct Drive Technology for Energy Recovery from Digester Biogas

    ABSTRACTThe Regional Municipality of Waterloo completed a study, with support from Environment Canada, to evaluate the feasibility of using direct drive technology to recover energy from digester biogas. The study identified that a 150 HP engine, operating at 54 % load, could be supported by the estimated gas production of 1560 m3/d with 63 % methane by volume. ...

  • Maximizing Energy Recovery through Digester Gas Management System Enhancement

    ABSTRACTAdvanced anaerobic digestion practices and maximum energy recovery call for a digester gas system that reliably allows for complete biogas collection and utilization. This paper will describe the planning, design, and construction of a new digester gas management system at the East Bay Municipal Utility District’s (District) Main Wastewater Treatment Plant. The need for an upgraded ...

  • Energy efficiency and emission reduction of TPM, PM2.5, and SO2 from natural gas and fuel oil fired boiler exhausts

    Fully 8% of all of Canada’s energy consumption occurs in gas and fuel oil fired boilers in commercial and institutional facilities1, with proportional amounts of greenhouse gases, particulate matter, and other pollutants. Recently particulate matter, and in particular that smaller than 2.5 microns (PM2.5) has garnered specific attention due to attributed health effects as demonstrated by ...

  • Recovery of Citrus Oil and Molasses: The Original Juice Company

     The Original Juice Company has realised the opportunity to recover valuable by-products from orange peel in the form of citrus oil and molasses. The installation of a vacuum distillation unit and a vertical tube evaporator required a capital cost of $1.1 million. A payback of 2 years from reduced trade waste charges and by-product sales (based on conservative market prices for citrus oil) ...
