Subject: MCU Draft Permit BACT Discussion - Air Assist Blower Information

S1R2.pdf

Shaheerah,

  

Attached is the information we discussed on the MCU Main Flare air‐assist blower and flare tip. The blower is currently

driven by a 2‐speed electric motor operating at 1,800 or 3,600 rpm, which produces a perimeter assist air flow volume of

2,060 scfm and 4,118 scfm respectively. In short, we think that the requirement to install a variable speed drive on the

blower is arbitrary, and that compliance with the NHV dilution parameter specified in the draft permit can be achieved

with the existing blower arrangement by properly staging the 2 speed blower based on the vent gas flow rate. The

blower does not run when the flare is in purge gas only mode.

WHEELS

STANDARD ALUMINUM

The unique Aluminum Pressure Blower

wheel is designed to provide efficient performance and reduced sound levels . . .

the dual-taper design concept on all but

the narrowest wheel sizes yields typical

efficiencies up to 10 percentage points

greater than conventional straight radial

wheels. Riveted high-strength aluminum

alloy blades and side plates minimize

overhung wheel weight and starting inertia. Ductile-iron, taper-lock hubs make

wheels easily removable. 

OPTIONAL STEEL

Either welded steel or stainless-steel wheel

construction is available in straight radial

design. AMCA Certified Ratings Seal applies

to Pressure Blowers with aluminum-wheel

design only. Air volume and pressure capabilities are the same as the dual-taper aluminum wheel, but brake horsepower

requirements are typically higher. Refer to

The New York Blower Company’s fan-selection program for details.

Note: Some fan-and-motor combinations with

steel wheels may be restricted due to starting

torque requirements. Consult nyb.

SAFETY EQUIPMENT

Safety accessories are available

from nyb, but selection of the

appropriate devices is the

responsibility of the systemdesigner who is familiar with

the particular installation, or

application, and can provide for

guards for all exposed moving

parts as well as protection 

from access to high-velocity

airstreams. Neither nyb nor its

sales representatives is in a

position to make such a determination. Users and/or installers

should read “Recommended

Safety Practices for Air Moving

Devices” as published by the 

Air Movement and Control

Association International,

Arlington Heights, Illinois.

SPARK-RESISTANT CONSTRUCTION [SRC]

Intended to minimize the potential for any two or more fan components to

generate sparks within the airstream by rubbing or striking during operation.

The following types are available:

AMCA A [AIRSTREAM] SRC

To include all airstream parts constructed of a spark-resistant alloy . . . maximum temperature: 200°F.

AMCA B [WHEEL] SRC

To include the fan wheel constructed of a spark-resistant alloy and a buffer plate

around the housing shaft-hole opening . . . maximum temperature: 200°F.
PAGE 5

CORRECTION FACTORS

Performance is based on actual cubic feet per minute

[ACFM] at the blower inlet at standard density [.075 lbs./ft.3

]

and static pressure at the blower outlet. Static pressure

capabilities are shown in inches water gauge [”WG].

Air density corrections are necessary for proper selection

when air density varies from the standard .075 lbs./ft.3 at

70 ̊F. at sea level. This also occurs when negative static

pressure exists [rarefication] on the inlet side of the fan.

Multiply the required static pressure at conditions by the

appropriate factors in Charts III, IV, and V to obtain corrected

pressure for blower selection. Pressure and BHP will be

reduced at conditions by the inverse of these factors.

Multiply one factor by the other if temperature, altitude, and

rarefication are non-standard. For example: If the installation

is located at an altitude of 4000 feet, the gas temperature

is 300°F., and the inlet pressure is –40”WG, the correction

factor is 1.84 [1.16 x 1.43 x 1.11].

PROCEDURE EXAMPLE

Determine the appropriate outlet size. The 06 outlet is selected for 800 CFM at 32”SP.

Plot the CFM and SP [standard] and select a performance curve for the fan size that meets or slightly

exceeds the required performance.

A Size 2106A will provide 800 CFM at 33.6”SP.

Determine the BHP required for the point of operation . . .

see page 4 for steel or stainless-steel wheel factors.

2106A requires 6.3 BHP.

2106S requires 7.2 BHP [6.3 x 1.15].

Read to the right to select motor horsepower. A 71⁄2 HP motor will cover both wheel types.

STEPS

SIZING NOMENCLATURE

number designates

the wheel diameter,

outlet size, wheel

type, and nominal

motor horsepower.

Note: the last two

digits showing

motor horsepower

are not required for

Arrangement 1

Pressure Blowers.

USING PERFORMANCE CURVES

Performance is shown according to outlet sizes for quick reference to duct diameter. Brake horsepower increments are 

identified on each curve. Recommended standard blower size

and motor combinations, which are based on the most efficient area of operation, are listed on page 12 for Arrangements

4 and 8, and on page 15 for Arrangement 4-V. Nonstandard

combinations are generally available, but are usually less 

efficient than the standard combinations.
