  • INTRODUCTION: HVAC BASICS

    The heating coils are fed from a heat source such as boiler or electricity. The heat from these coils is transferred to the air passing over it. System Variations: 1. An outside air duct can be found either before the cooling coil or before the filters on …Learn More

  • Thermal Power Plant Components - Thermodyne Boilers

    The flue gases leaving the boiler also contain some ash particles, so to reduce the air pollution, flue gases are allowed to pass through the Dust Collectors and Bag Filters to remove the ash particulates from the flue gases and are sometimes passed through the Wet Scrubbers to decrease the sulfur content from the gases.Learn More

  • Boiler Maintenance Tips | DoItYourself.com

    Jan 26, 2010 · Boiler maintenance is a must if you hope to have your boiler efficient at all times. Boilers give a vital service in hot water supply and household warming. They add to the comfort level of the home. Too often, repairs become necessary when the boiler malfunctions.Learn More

  • Boiler Safety - Occupational Safety and Health Administration

    Corrosion weakens boiler metal by the thinning (removal) of the metal. Corrosion causes pitting and channeling of the metal, which results in the thinning of tubes, piping, and other boiler components. Corrosion is primarily caused by oxygen in the boiler water. Feedwater is treated to remove oxygen by heating and/or chemical treatment.Learn More

  • The Kraft Recovery Process - TAPPI

    NOx emissions from recovery boilers are relatively low, typically 50 to 100 ppm. Most of this NOx comes from the small amount of nitrogen compounds (0.1 wt%) in the black liquor solids burned in the boiler [3,4]. At present, it is not clear if NOx emissions can be controlled through changes in boiler operating practices. NOx emissions fromLearn More

  • Beyond Primary / Secondary Piping - Caleffi

    Modern compact boilers have much higher flow resistance than cast iron boilers. condensing/ Consider a system that supplies 500,000 Btu/hr at design load. Flow in the primary loop is 50 gpm with a corresponding head loss of 15 feet (6.35 psi Because hydraulic separators remove sediment from systems they're ideal forLearn More

  • Boiler Safety | OSHA Safety Manuals

    Mar 15, 2017 · Boiler Safety. Workers that use, maintain, and service boilers know that they can be potentially dangerous. Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam. The steam is superheated under pressure and used for power, heating or other industrial purposes.Learn More
