Performance Specifications




   Heat Output (Capacity)
 
     This is the boiler's heat output expressed as a range. When units of boiler horsepower are used, this value is sometimes referred to as capacity. Note that 1 boiler horsepower (BHP) equals 33,472 Btu/hour.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Maximum Temperature
 
     The boiler's maximum operating temperature.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Maximum Pressure
 
     The boiler's maximum operating pressure.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Efficiency
 
     Efficiency is defined as the energy input minus stack loss, divided by the energy input. Efficiency is sometimes referred to as thermal efficiency.
 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
Configuration




   Type       
   Your choices are...
 
      
 
   Hot Water
 
     The boiler is used to produce hot water.
 
   Steam
 
     The boiler is used to produce steam.
 
   Other
 
     Other unlisted boiler types.
 
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Technology       
   Your choices are...
 
      
 
   Cast Iron
 
     Cast iron boilers are limited to low-pressure steam or hot water applications. Typically, they range in size from 25 to 200 horsepower.
 
   Composite / Hybrid
 
     Composite boilers are combinations of two or more boiler types.
 
   Firebox
 
     Firebox boilers use a similar attachment technique as firetube boilers. Their combustion chambers are not round, like the cylindrical furnace of a firetube. Typically, firebox boilers are designed for low-pressure steam or hot water applications.
 
   Firetube / Scotch Marine
 
     Firetube or scotch marine boilers feature a design in which combustion gases flow inside the tubes and water flows outside the tubes. They are sometimes called smoke tubes.
 
   Fluidized Bed
 
     Fluidized bed boilers include bubbling fluidized bed (BFB), circulating fluidized bed (CFB), and pressurized circulating fluidized bed (PCFB) products.

Bubbling fluidized-bed boilers are particularly efficient when firing fuels with low heating value and high moisture and ash content.

Circulating fluidized-bed technology is a very flexible option for the clean combustion of many fuels, including waste coals, petroleum coke, and even shredded automobile tires.

Pressurized circulating fluidized bed boilers operate with efficiencies exceeding those of many conventional power plants firing pulverized coal. This technology has the potential to reduce the cost of energy and further cut the emission of acid-rain gases in utility and industrial applications. In addition to minimizing emissions of sulfur dioxide and nitrogen oxides, combined-cycle PCFB technology permits the cost-effective firing of fuels that otherwise could not be used in an environmentally acceptable manner.
 
   Radiant Boiler
 
     Radiant boilers feature a single drum construction to overcome various limitations posed by bi-drum boilers for high-pressure applications.
 
   Steam Generator
 
     The heat exchanger used in some reactor designs transfers heat from the primary (reactor coolant) system to the secondary (steam) system. This design permits heat exchange with little or no contamination of the secondary system equipment.
 
   Water Tube
 
     Water tube boilers have a heating surface that consists of a large number of relatively small-diameter tubes that contain the water. The heat is applied to the external side of the tubes.
 
   Other
 
     Other unlisted technology types.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Orientation       
   Your choices are...
 
      
 
   Vertical
 
     The boiler is oriented vertically to save floor space.
 
   Horizontal
 
     The boiler is oriented horizontally for low clearance.
 
   Other
 
     Other unlisted orientation.
 
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Features




           
   Your choices are...
 
      
 
   ASME Certified
 
     The boiler is manufactured to ASME certifications.
 
   Commercial / HVAC
 
     The boiler is designed for commercial or HVAC applications.
 
   Deaerator / Separator
 
     Deaerators are vessels in which boiler feedwater is heated under reduced pressure in order to remove dissolved air.
 
   Economizer
 
     Economizers are heat exchangers that transfer heat from the gases of combustion to the boiler feedwater.
 
   Low Emissions
 
     Low emissions boilers are designed to reduce the release of sulfur oxide, nitrogen oxide and other emissions.
 
   Monitor / Controller
 
     The boiler has a monitoring or controlling mechanism.
 
   Multiple Boiler System
 
     Multiple installation boilers are used to obtain maximum performance and greater efficiency.
 
   Safety Valve
 
     Safety valves are spring-loaded valves that open automatically when pressure attains the valve setting. They are used to prevent excessive pressure from building up in a boiler.
 
   Skidded / Packaged
 
     The boiler is mounted on a skid or comes in a packaged configuration.
 
   Superheater
 
     Superheaters are banks of tubes in the exhaust gas duct after the boiler. They are used to heat the steam above the saturation temperature.
 
   Water Treater / Conditioner
 
     Water treaters or conditioners remove minerals from boiler water that could lead to scaling.
 
   Other
 
     Other unlisted features.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Fuel Type / Heat Source       
   Your choices are...
 
      
 
   Coal
 
     The boiler is powered by pulverized coal.
 
   Electric
 
     The boiler is powered by electricity.
 
   Gas (Natural / Propane)
 
     The boiler is powered by gas. Natural gas and propane are common types.
 
   Oil
 
     The boiler is powered by oil.
 
   Steam / Hydronic
 
     The boiler is fueled by steam or hot water.
 
   Waste Heat / Indirect
 
     Waste heat boilers are designed to burn waste or tail gasses to generate steam for process and/or power.
 
   Wood
 
     The boiler is powered by wood.
 
   Other
 
     Other unlisted fuel types.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
