    FEATURES AND BENEFITS

    In addition to the features provided on all Cleaver-Brooks Firetube Boilers, the following features apply specifically to Model CB Firetube Boilers. The CB four-pass dryback boiler is the premium firetube boiler design available.

    Four-Pass Dryback Design:

    Four-pass design provides high flue gas velocities and low stack temperature for guaranteed maximum efficiency.

    Dryback design provides full access to boiler tubes, tube sheet, and furnace for ease of maintenance.

    Dryback design includes single rear tube sheet construction, providing reduced tube sheet stresses.

    Five Square Feet of Heating Surface per Boiler hp:

    Maximum heat transfer with minimum thermal stresses provide guaranteed efficiency and long boiler life.

    Highest guaranteed fuel-to-steam efficiencies.

    Low Furnace Location

    Furnace located well below water level with generous clearance from bottom of boiler, allowing proper circulation.

    Low furnace provides additional safety margin between furnace and water level.

    Reduces water carryover, producing drier steam.

    Hinged or Davited Front and Rear Doors:

    Provides full access to front and rear tube sheet and furnace.

    Reduces maintenance costs.

    High Turndown Burner:

    4:1 turndown (gas and oil) is standard on boilers up to 250 hp.

    Guaranteed 10:1 turndown (gas fired) 8:1 (No. 2 oil fired) standard on 250 hp through 800 hp.

    Advanced burner design provides maximum combustion efficiencies and high turndown.

    Reduced boiler cycling and maintenance.

    Boiler stays on line during low load conditions for optimum efficiency and performance.

    Gas, No. 2 Oil, No. 6 Oil, and Combination Gas and Oil Burners Available:

    High radiant multi-port gas burner designed for high gas velocities and complete fuel/air mixing, providing maximum combustion efficiencies.

    Air atomizing oil burner available for proper oil atomization, maximum combustion efficiency, and low maintenance requirements.

    Air atomizing compressor provided with the boiler package for clean oil burning and ease of maintenance.

    Combination gas/oil burners provide quick fuel changeover without re-adjustment of the burner.

    Fuel oil controller eliminates the need for over 40 connections, combining gauges, valves, and regulators into a single casting.

    Retractable oil nozzle provides easy access and cleaning and eliminates coking of oil and nozzle tip when firing gas.

    Low NOx Capability Available:

    20 ppm NOx guarantee available on Model CB (LE) Boilers.

    PRODUCT OFFERING

    Model CB Firetube Boilers are available in low pressure steam, high pressure steam, and hot water designs. Burners are available to fire natural gas, light oil, heavy oil, or a combina-tion of oil and gas. Optional alternate fuel burners are also available.

    Model CB Boilers include:

    Four-pass dryback design.

    15 hp through 800 hp.

    150 psig - 350 psig high pressure steam.

    15 psig low pressure steam.

    30 psig or 125 psig hot water.

    Natural gas, light oil, or heavy oil firing.

    The Model CBBoiler is the premium firetube product offering providing maximum boiler efficiency, the widest range of size and pressures, and premium control packages.

    Available options: For option details, contact your Cleaver-Brooks authorized representative. Options include the following:

    Boiler Options

    Auxiliary low water cut-off (standard on steam boilers).

    Drain valves.

    Additional screwed or flanged tappings.

For specific efficiencies on firetube boiler offerings not listed here, contact your local Cleaver-Brooks authorized representa-tive.

    Cleaver-Brooks offers an industry leading fuel-to-steam boiler efficiency guarantee for Model CB Firetube Boilers. The guar-antee is based on the fuel-to-steam efficiencies shown in the efficiency tables and the following conditions. The efficiency percent number is only meaningful if the specific conditions of the efficiency calculations are clearly stated in the specifica-tion (see Cleaver-Brooks publication CB-7768 for a detailed description of efficiency calculations).

    The boiler manufacturer shall guarantee that, at the time of startup, the boiler will achieve fuel-to-steam efficiency (as shown in the tables listed above) at 100% firing rate (add effi-ciency guarantees at 25%, 50%, and 75% of rating, if required). If the boiler(s) fail to achieve the corresponding guaranteed efficiency as published, the boiler manufacturer will rebate, to the ultimate boiler owner, five thousand dollars ($5,000) for every full efficiency point (1.0%) that the actual efficiency is below the guaranteed level. The specified boiler efficiency is based on the following conditions.

    1. Fuel specification used to determine boiler efficiency:

    Natural Gas

    Carbon, % (wt) = 69.98Hydrogen, % (wt) = 22.31Sulfur, % (wt) = 0.0Heating value, Btu/lb = 21,830

    No. 2 Oil

    Carbon, % (wt) = 85.8Hydrogen, % (wt) = 12.7Sulfur, % (wt) = 0.2Heating value, Btu/lb = 19,420

    No. 6 Oil

    Carbon, % (wt) = 86.6Hydrogen, % (wt) = 10.9Sulfur, % (wt) = 2.09Heating value, Btu/lb = 18,830

    2. Efficiencies are based on ambient air temperature of 80 F, relative humidity of 30%, and 15% excess air in the exhaust flue gas.

    3. Efficiencies are based on manufacturers published radiation and convection losses. (For Cleaver-Brooks radiation and con-vection losses, see Boiler Efficiency Facts Guide, publication

    number CB-7767).

    4. Any efficiency verification testing will be based on the stack loss method.

    When specifying the efficiencies in the tables, be sure to include the specific guarantee conditions to maximize the effectiveness of your efficiency specification. If you have any questions regarding the efficiency specifications, please con-tact your local Cleaver-Brooks authorized representative. For efficiencies and stack temperatures at operating pressures not listed, follow these procedures:

    When the operating steam pressure is between 10 psig and 125 psig, interpolate the values from the efficiency tables.

    When the operating steam pressure is above 125 psig, esti-mated efficiency can be calculated as follows:

    Example:

    Boiler: 350 hp.

    Fuel: natural gas.

    Operating steam pressure: 200 psig.

    Find the fuel-to-steam efficiency at 100% firing rate. From Table A2-8 for a 350 hp boiler operating at 100% firing rate and an operating steam pressure of 125 psig, the efficiency is 82.5%.

    Using Figure A2-8, note that the stack temperature increases 36 F at the higher operating pressure. To estimate boiler effi-ciency, use this rule of thumb: For every 40 F increase in stack temperature, efficiency decreases by 1%. Since the stack tem-perature rise is 36 F, the decrease in the boiler efficiency at 200 psig operating pressure is calculated as follows: 36/40 = .9%. Therefore, the boiler efficiency at 200 psig operating pressure is 82.5 - .9 = 81.6%.

    Emissions The emission data included in this section consists of typical uncontrolled emission levels for Cleaver-Brooks Model CB Firetube Boilers.

    Cleaver-Brooks Firetube boilers are available with the standard burner package for Model CB, or optional internal flue gas recirculation on Model CB (LE) (refer to Section A3).

    ENGINEERING DATA The following engineering information is provided for Model CB Firetube Boilers. Additional detail is available from your local Cleaver-Brooks authorized representative. Refer to Tables A2-14 through A2-18.

    Blowdown Water Requirements Some local codes require blowdown tanks to be constructed in accordance with recommendations of the National Board of Boiler and Pressure Vessel Inspectors.

    The National Boards recommendations base the size of the blowdown tank on the removal of at least 4 inches of water from the boiler.

    Table A2-19 lists the approximate quantity of water repre-sented by 4 inches of water at normal operating level for Cleaver-Brooks Model CB Boilers.
