Insulation and Liner

All internal insulation shall be designed to provide a casing surface temperature of 140F based

on a 100F ambient and a 5 MPH wind. Selected small localized areas can be expected to

exceed the design skin temperature requirement. These small areas would include casing test or

instrumentation connections, support attachment points for flow distribution devices and similar

areas. The Vendor’s HRSG design will minimize on a practical basis the skin temperature

excursion.

HRSGs that are "walled in," should be provided with fresh air to maintain the required ambient.

The air must be provided at, or very near, the ground level so that the bottom of the unit has

ample fresh air to maintain natural convection currents and does not become a region of high

temperature stagnant air with a resulting high surface temperature. Insulation design data is

included in the Technical Data section of this proposal.

6.0 Shop Assembly / Modular Construction

The HRSG Vendor proposes a modular construction design for the HRSG to minimize the field

erection time.

The modular construction consists of the following:

Inlet Duct - Inlet ducts are shipped in “flat panels” and/or "C” sections as determined by final

shipping clearances for unescorted truck shipments to the jobsite. Internal insulation and

stainless steel liner at the field joints must be installed in the field. These field joints are

furnished with 2” sky climber ports in the top panels of the inlet duct for use during construction.

Module Harps - The heating surface consists of the standard “module harp” design. Each

“module harp” consists of two or three rows of tubes with top and bottom headers. The tubes are

welded to the headers using full strength welds.

Module Bundles – Assemblies of two or more module harps with interconnecting piping

installed. Limited structural members are included for bundle support during shipment and for

permanent installation. Top casing and penetrations are sometimes included. Maximum

shipping dimensions and weights are approached.

Module Boxes – Module Bundles with HRSG outer casing and support steel installed.

Additional support steel is required for shipment and must be removed prior to final assembly.

Nearly all internal and interconnecting piping is installed. Module Boxes represent the

maximum degree of shop assembly.

Steam Drum - the internal surface of the drums are grit blasted prior to installation of internals.

Steam drums are shipped with shop installed internals and riser tube stubs.

Casing - Casings will be constructed of ¼ inch, minimum, A-36 carbon steel plate externally

reinforced with structural steel stiffeners. All stiffeners will be seal welded to the casing to

prevent corrosion behind the structurals. The casings and ductwork will be designed for an

internal pressure of +/- 20 in. w.c.

All casings will be internally lined with blanket insulation covered by 16 Ga., minimum, 409

stainless steel liner panels, held in place by 3/8” diameter studs. In areas not directly in the gas

path (top and bottom casing), expanded metal, or equal, will be utilized to support and retain the

insulation. Stainless steel bellows seals will be provided where piping or support rods penetrate

the casing. Casing drains will be furnished. Drain piping will terminate in convenient collection

points at the side of the unit.

Support Steel - HRGS main support steel, columns, beams and baseplates will be carbon steel to

AISC requirements. Base plates will have lateral expansion provisions where required. All

pressure part heating surface is top supported from adjustable support rods with clevises, which


Document Title:


Page No.:

connect between intermediate top steel members and are pinned to support lugs on the module

harp upper headers.

Platforms, Ladders, and Stairs - Platforms, ladders and stairs will be assembled into sections (as

large as practical) as determined by final shipping clearance for unescorted truck shipments to

the job site. Platform grating will be shop installed. Typical sizes for these items are as follows:

Platform section with grating attached: 8’0” wide (max.) x 20’ long.

Handrails with toe plates attached: 20’ long

Stair stringer assemblies with steps shop installed

Ladders: 20’ long

Stack - The stack and stack inlet breaching will be fabricated in sections as determined by

shipping clearances for unescorted truck shipments to the jobsite.

Large Bore Piping Spools (2-1/2” & Larger) - Large bore piping spools will be shop assembled

in sections as follows:

Superheater & Economizer Inlet & Outlet Headers - All inlet and outlet headers will have

shop installed stubs to connect the header to the HRSG. The ends of the stubs will be

beveled and coated with an anti-corrosion material. For single wide units, the headers will be

shipped in one piece.

For double and triple wide units, the headers will be shipped in two pieces. One piece will be

furnished with the end beveled and coated. The other piece will be shipped with extra

material for field cutting as required.

Interconnecting Piping & Attemperator Loops - Interconnecting piping and attemperator

loops will be provided in spools with extra material on one end to allow for field fit-up.

Large Bore Valves - All steam outlet large bore valves shall be field installed. Feedwater

control valve stations shall have all valves shop assembled.

Isometric drawings of each piping assembly will be provided.

8.0 Heat Recovery Steam Generator Trim Lists

Notes

1. The safety valves will be furnished with gags, vents, stacks, and supports. Safety valves shall

be manufactured by Consolidated, Farris, or Crosby.

2. Double block to be achieved by manifolding and using one valve for second valve.

3. The suppliers named in the trim list are to indicate the quality of equipment proposed. The

Company reserves the right to substitute equal or superior quality equipment to those names.

Factory Setting Vs. Field Setting of Safety Valves

Every safety valve is set and adjusted on steam before shipment from the factory. Blowdown

adjustments are made as carefully and accurately as possible on the factory test boiler. However,

it must be recognized that actual field operating conditions may vary considerably from factory

test conditions.

Conditions beyond manufacturer's control that affect safety valve operation are:

1. Quality of steam being discharged.

2. Discharge piping stresses and back pressure.

3. Ambient temperature.

4. Shipping or storage damage.

5. Improper gagging.

6. Improper bolting of flanges.

7. Damage due to foreign material in the steam.

It is the responsibility of the Purchaser to procure the services of the safety valve manufacturer or

a safety valve assembly company certified by ASME to use "V" stamp, to perform final safety

valve adjustments in the field.

10.0 Boiler Water Limits

Boiler water concentrations shall not exceed the following:

Test Procedure for Solids in Steam

All sampling and testing is to be conducted by the Purchaser according to the methods

prescribed by the American Society for Testing Materials.

It is the responsibility of the Company to provide the sampling nozzles and connections, etc.,

for proper sample taking according to ASTM standards.

All methods, rules and practices given in Section 11 of Annual Book of ASTM Standards

(latest edition), as applicable, should be used in determining the solids in steam.

Some of the specific applicable standards are:

D-1192 Equipment and Sampling Techniques

D-3370 Sampling of Water

D-3864 Continuous Sampling of Water

D-1066 Sampling of Steam

D-2777 Determination of Precision and Bias

The solids in the steam shall be determined by sodium tracer method using sodium ion

electrode, ASTM D-2186, Method C.

Vaporous carryover of silica or any other gases are not included in the solids in steam.

If the Purchaser determines that the solids in steam exceed the guaranteed value, after

correction for water conditions, a report prepared by the Purchaser or his agent, along with

the raw data, shall be given to the Company for analysis.

The Company reserves the right to ask for a re-test if it feels that all the guidelines were not

followed.

A detailed test procedure will be prepared by the Company after the award of the order.

Notes:

(1) Actual values within the range reflect the TDS in the feed water. Higher values are for high solids, lower values are for low solids in

the feed water.

(2) Actual values within the range are directly proportional to the actual value of TDS of boiler water. Higher values are for the

high solids, lower values are for low solids in the boiler water.

(3) Dictated by boiler water treatment.

(4) These values are exclusive of silica.

(1) Alkalinity not to exceed 10 percent of specific conductance.

(2) Minimum level of OH alkalinity in boilers below 100 psi must be individually specified with regard to silica solubility and other

components of internal treatment.

*** Zero in this case refers to free sodium or potassium hydroxide alkalinity. Some small variable amount of total alkalinity will be present and

measurable with the assumed congruent control of volatile treatment employed at these high pressure ranges.
