Product Review Cameron Abney and Associates Frequently Asked Questions

Product Review Cameron Abney and Associates Frequently Asked Questions

BRS, through its associate boiler rental suppliers, will assist in emergency and planned rentals to minimize or eliminate disruption in operation.

Frequently Asked Questions

Who supplies the fuel and power for the boiler?

Who supplies the main gas pressure regulator?

Who provides the insurance for the boiler?

Who is paying for the freight?

Who will hook up the boiler and what needs to be done?

Who supplies the fuel and power for the boiler?

The fuel and power supply for the boiler are the responsibility of the Lessee. BRS also secures portable generator sets if you require power for your application. Trailer mounted units up to 350HP have oil storage tanks on board. Those units require the tank to be filled after the trailer is blocked and leveled. All oil MUST be removed prior to return of rental boiler. Units larger than 350HP will require a separate oil tank to be provided and filled. Many times a local fuel supplier can provide this tank at little or no charge when purchasing oil. An oil transfer pump may be required depending on the location of the oil tank. The trailer power requirements are 240/460 Vac, three phase and 120 Vac, control. Note that some units have separate control power transformers and do not require 120 VAC power. If power is not available, portable generator sets can be provided.

Return to top

Who supplies the main gas pressure regulator?

Typically the Lessee provides the gas pressure regulator to supply trailer with proper pressure. If required, BRS sells gas pressure regulators for your application. Advise the sales department when you place your order or are inquiring about a price.

Return to top

              

Who provides the insurance for the boiler?

It is the responsibility of the Lessee to provide full protection for the boiler and equipment.  Check with your insurance agent, many policies will cover this with no increased premiums or extra charges involved. A certificate of insurance will be required prior to start-up.

Return to top

Who is paying for the freight?

The Lessee pays the freight to the site and the return of the unit after the rental period. Trucking arrangements are made by BRS or Lessor and will be coordinated with the trucking company.

Return to top

                                                           

Who will hook up the boiler and what needs to be done?

The hook-up of the boiler will be done by the Lessee, which includes the following tasks before a start-up technician is called.

Unload and level the boiler unit or level and block the tires for trailer mounted units.

Connect the 3 phase and 120 Vac control power as required to the safety disconnects.

Provide make-up water supply to the feed connection. Minimum of 40 psig.

Provide steam piping from the trailer to the process connection.

Provide a regulated natural gas service or PROPERLY REGULATED propane tank for 200,000 BTUs pilot gas.

Supply and fill oil tank when burning #2 oil. Gas pilot required when firing oil.

Provide condensate return piping. This is not required, but returning condensate will reduce make-up water usage and reduce energy cost.

Pipe any drains to safe areas, water and steam is a hazard to personnel or property. Local code MUST be consulted.

Return to top

                                             

What about the water chemical treatment

Chemical treatment for the boiler must be provided for any length of rental. The Lessee must provide the proper chemical treatment program. Proper blow down of the equipment and treatment will prevent damage to the boiler. BRS can provide the proper boiler chemicals and chemical treatment services at start-up and during the rental period. Please advise when the lessee does not want the responsibility of chemical treatment. BRS also has a third party chemical treatment company that can also provide chemicals and services when needed.

Product Review Cameron Abney and Associates Formulas and Conversion Charts

Product Review Cameron Abney and Associates Formulas and Conversion Charts

A.            Boiler Formulas

Boiler Horse Power (HP):

BHP = (Lb/hr) * FE / 34.5

where Lb/hr is pounds of steam per hour and FE is the factor of evaporation.

Steam:

S=HP * 34.5 * t

where HP is boiler horsepower and t is time (h).

Cycle of Concentration of Boiler Water:

CYC=Bch / FCh

where  Bch  is  ppm  water  chlorides  and FCh is ppm feedwater chlorides.

Differential Setting (lb):

Delta S = P1 - P2

where P1 is the cutout pressure and P2 is the cut in pressure

Factor of Evaporation:

FE = SH + LH / 970.3

where SH is the sensible heat and LH is the latent heat.

Force (lb):

F=P / A

where P is pressure (psi) and A is area (in^2).

Horsepower (HP):

HP=(d * t) / (t * 33000)

where d is distance, F is force, and t is time.

Inches of Mercury (in):

InHG=P / 0.491

where P is pressure

Percent of Blowdown:

%BD=(PP - RP) / PP

where PR is popping pressure and RP is reseat pressure

Rate of Combustion (Btu/hr) RC=H / (Vf * t)

where H is heat released (BTU), Vf is volume of furnace (ft^3), and t is time (hr).

Return Condensate Percentage in Feedwater RC%=(MC – FC) / (MC – CC)

where MC is the makeup conductivity (μohms), FC is the feedwater conductivity (μohms), and CC is the condensate conductivity (μohms).

Static Head Pressure (lb)

SHP= Bpr * 2.31

where Bpr = boiler pressure (psi)

Temperature Conversions:

F to C

C = (F – 32) / 1.8

C to F

F = (1.8 * C) + 32

Total Force (lb)

TF = P*A

where P is pressure (psi) and A is the area of valve disc exposed to steam (sq. in.)

Water Column (in)

WC = P / 0.03061   where P is pressure (psi).

B. Combustion Chemistry

Flue gas analysis:

Boiler flue gas analysis is used to determine combustion efficiency.
Carbon Dioxide (CO2)	Indicates complete combustion
Carbon Monoxide (CO)	Indicates incomplete combustion
Oxygen (O2)	Indicates the presence of excess air
Oxides of Nitrogen (NOx)	A product of high temperature combustion
Combustibles	Material that burns when exposed to oxygen and heat

It is typical to target oxygen levels of 8% in low fire and 3% in high fire for gas fired burners.

It is typical to target oxygen levels of 6% in low fire and 4% in high fire for oil fired burners.

Johnston Boiler Company  recommends  no greater level than 200 ppm of Carbon Monoxide in its burner operation. The acceptable “Industry Standard” level is 400 ppm or less.

Johnston Boiler Company recommends zero combustibles for a gas fired burner.

Johnston Boiler Company recommends a maximum #2 Smokespot (Ringelmann Chart) in its oil fired burner.

Air Properties:

For a burner originally adjusted to 15% air, changes in combustion air temperature and  barometric pressure cause the following in excess air:

Air Temperature	Barometric Pressure (In. HG)	Resulting Excess Air %*
40	29	25.5
60	29	20.2
80	29	15.0
100	29	9.6
120	29	1.1
80	27	7.0
80	28	11.0
80	29	15.0
80	30	19.0
40	31	34.5
60	30	25.0
80	29	15.0
100	28	5.0
120	27	-5.5

* Expressed as a percent of the Stoichiometric air required.

C. Energy Loss From Scale Deposits

ENERGY LOSS FROM SCALE DEPOSITS IN BOILERS
SCALE THICKNESS (INCHES)	EXTRA FUEL COST (PERCENT)
1/32	8.50
1/25	9.30
1/20	11.10
1/16	12.40
1/8	25.00
1/4	40.00
3/8	55.00
1/2	70.00
