How We Make Steam

System Design

Fired Steam Generators For Saturated Steam

Steam Output 20 to 1300 Boiler Horsepower 0.3 to 20 t/h Steam Output

Pressure 1 - 208 bar (3000psi)

Fuel Gas, #2, #6 Oil, Marine Oil/Gas

Fired Steam Generators For Superheated Steam

Steam Output 20 to 1300 Boiler Horsepower 0.3 to 20 t/h Steam Output

Pressure 1 - 57 bar (850psi)

Temperature Up to 878°F (470°C)

Fuel Gas, #2, #6 Oil, Marine Oil/Gas

Exhaust Gas Heat Recovery Saturated and Superheated Steam and Hot Water

Exhaust Gas Flow of 4 t/h to 180 t/h

Exhaust Gas Inlet Temp of 250°C to 560°C

Heat Recovery of 0.1 to 4 MW

Steam output of up to 6.5 t/h

Exhaust Boiler System

Combination System

Low Emissions Systems

• Flue Gas Re-circulation – Emissions on Gas NOx to 30 ppm CO to 200 ppm

• Bluff Body – Emissions on Gas

NOx to 12 ppm – units < 500 BHP NOx to 20 ppm – units > 500 BHP CO to 50 ppm

• Fiber Metal Burner – Emissions on Gas NOx to 9 ppm CO to 20 ppm

Super Economizer

• Clayton SE Steam Generator -

Stack Temperature is 80°-100°F below steam temperature.

• Firetube Boiler -

Stack temperature is 80°-100° F over steam temperature. • 40° F of stack temperature equals 1% of fuel to steam efficiency • Clayton Steam Generator is 4-5% inherently more fuel efficient.

The Clayton Advantage

Advantages that result in reduced cost and increased operating flexibility 10

1. Safety

The unique Clayton design is inherently safe with no possibility of a hazardous steam explosion

2. Lower Weight And Space Requirements

300hp Boiler Comparison

Footprint Area Clayton – 69 sq ft Firetube – 157 sq ft

Filled Weight Clayton – 9,300lbs Firetube – 25,000lbs

• Means Lower Installed Cost • More space and weight for other equipment

3. Fast Start-Up

Cold Start to Full Output 15 to 20 Minutes for Clayton Vs. 45 Minutes for Firetube Boilers

4. Fast Response to Load Swings

5. No level control

Boiler is of forced flow design No need for level control which can affect performance in dynamic situations

6. Higher Efficiency

7. Reduced Blowdown

Clayton • Blowdown loss of 0.14% • TDS of 8500 Firetube Boilers • Blowdown loss of 5.7% • TDS of 3500

Lower Blowdown results in Higher Efficiencies

8. High Quality Steam

• 99.5% Steam Quality • More useful heat to the process • Less fouling of piping and devices • More consistent steam quality • Eliminates carryover

9. Packaged Systems

Reduced Installation Time and Cost

10. PLC and Linkageless Controls

• Remote Monitoring and Control • Tie into Plant Control Systems • Better control across the operating range • Improved efficiency • Reduced emissions and maintenance

Feedwater Systems

• Atmospheric Deaerator (Hotwell)

• Pressurized Deaerator

• Semi-closed Receiver

• Trap Separator Arrangement

29

Hotwell Feedwater System

CHARACTERISTICS • Water maintained at 190 – 200 Degrees F • Feedwater at atmospheric pressure • Reduces oxygen to 1 – 2 ppm ADVANTAGES • Lowest initial cost • Easiest system to maintain • Quick start-up and response to load changes

DISADVANTAGES • Relatively high chemical use – lowest natural oxygen removal

Deaerator Feedwater System

CHARACTERISTICS • Water maintained at 225 – 235 Degrees F • Feedwater maintained at 5 – 7 PSIG (typically) • Reduces oxygen to 7 – 10 ppb

• Requires PRV and BPR • Requires a small vent

ADVANTAGES • Very good oxygen removal – less chemical use than with a Hotwell

DISADVANTAGES • Higher first cost than a Hotwell • Less stable than Hotwell under varying loads

33

Semi-Closed Receiver (SCR) Feedwater System

CHARACTERISTICS • Water maintained at 285 – 350 Degrees F • Feedwater pressure maintained at 50 – 125 PSIG • Requires a PRV and BPR • Requires a small vent • Economical with relatively high condensate at relatively high pressure

ADVANTAGES • up to 13% fuel savings compared to a Hotwell

DISADVANTAGES • Higher first cost than a Hotwell • More complex system to maintain than a Hotwell

Feedwater Treatment

• Hardness

• pH

• Oxygen

• Total Dissolved Solids

37

Hardness Control

• Calcium & Magnesium Form Scale

• Remove with a Water Softener

• Zero hardness for a Firetube and a Steam Generator

39

40

Feedwater pH Control

• Steam Generator 10.5 - 12.5

• Firetube - Internal 10.5 - 12.5

• Firetube - Feedwater 8.5 - 9.5

41

Oxygen Control

• Dissolved Gases Cause Corrosion & Pitting

• Pre-Heat Feedwater

• Add Sulfite

43

Total Dissolved Solids Control

• High Levels Cause:

• Carryover

• Foaming

• Blowdown TDS:

• Firetube - 3500 ppm

• Steam Generator - 8500 ppm Feedwater

- 30,000 to 40,000 ppm Blowdown

45

Clayton Feedwater Treatment

Objectives of Water Treatment:

• Prevention of scale and corrosion

• Maintain generator integrity and longevity

• Maintain efficiency and minimize downtime

• Prevent costly repairs due to coil failure

Water Testing Frequency:

• Daily or once a shift

Off-line Lay-up:

• Follow procedures for dry or wet shut down Water Treatment Log:

• Use Clayton AWARE program

46

Clayton Feedwater Chemicals

Clayton Coil Guard Technology

• Specifically formulated for use in a Clayton Steam Generator • Contain a passivating agent to minimize corrosion. • Single drum formulations are available for any operating condition. • Specific for high TDS conditions in a Clayton unit. • pH may be controlled without an additional product.

• Supported by Clayton’s AWARE program

Note: Feedwater treatment chemicals from third party suppliers may be suitable for Clayton Steam Generators. Consult your Clayton Sales Engineer for requirements .
