  • Boiler Operations That Affect Efficiency (Part 1)

    Part 1: Operating techniques for maximum efficiency. Fuel is a major cost in boiler operation. It is therefore important to minimize fuel consumption and maximize steam production. Although a boiler's efficiency is primarily a result of its design, the operator can maintain or significantly improve efficiency by controlling losses to the Learn More

  • 1.4 Natural Gas Combustion

    The rate of CO emissions from boilers depends on the efficiency of natural gas combustion. Improperly tuned boilers and boilers operating at off-design levels decrease combustion efficiency resulting in increased CO emissions. In some cases, the addition of NOx control systems such as lowLearn More

  • GAS BOILERS VS. WASTE WOOD BOILERS

    represents a boiler operating at full firing rate. This number was chosen for example only and is not generally the way a natural gas boiler operates. Generally, a gas fired boiler will modulate between minimum and maximum and average out at something less than firing rates, which in turn lowers the hourly cost of operation.Learn More
