Clayton currently offers Fired Steam Generators and Fluid Heaters in 18 sizes ranging from 25 to 1000 Boiler Horsepower (245 to 9,810 kW) and 862 to 34,500 pounds of steam per hour (391 to 15,650 kg/hr). These controlled-flow water tube boilers units are built to appropriate national and local standards, using high quality materials and workmanship. Units are designed to burn natural gas, propane, light oil and heavy oil, as well as a combination of these fuels and are available with steam design pressures up to 3000 psig. Two product lines are offered. One product line covers from 25 to 200 BHP (245 to 1,962 kW) or 863 to 6,900 pounds per hour (391 to 3,130 kg/hr). The other covers from 150 to 1000 BHP (1,472 to 9,810 kW) or 5,175 to 34,500 pounds per hour (2,347 to 15,650 kg/hr).

A special Superheat version of the E–Series product is offered  which provides superheated steam and is available in a variety of sizes from 200 to 1000 BHP (1,962 to 9,810 kW) for a range of steam pressures and temperatures.

Clayton also offers an unfired line of Waste Heat and Exhaust Gas Steam Generators in a wide variety of configurations and sizes. This product line features many of the same benefits as our fired units and can also be used in combination with fired units.

All our units can be supplied with complete Feedwater Treatment Systems and with factory Skid Mounting to reduce field installation costs.

Additionally, our Chemical Division boasts a complete line of Feedwater Treatment Chemicals, especially designed for our steam generators.

The unique design of the Steam Generator and the manner in which steam is produced leads to the numerous advantages that the Clayton equipment provides. Among the many benefits included are:

  • Reduced space requirements
  • Higher fuel efficiency
  • Rapid startup and load response
  • Lower blowdown rates
  • Higher quality steam output
  • Inherent higher level of operator safety

How We Make Steam

A Clayton Steam Generator is a once through, forced flow, water tube boiler utilizing a steel helical coil heat exchanger. All Clayton steam generators, both fired or unfired, contain three main components: a helical coil heat exchanger, the positive displacement feedwater pump and the mechanical steam separator.

The feedwater pump is a heavy duty, pack-less and seal-less positive displacement unit that is designed and manufactured by Clayton. When the steam generator is in operation, the pump continuously supplies feedwater to the helical coil heat exchanger, where heat is transferred from the products of combustion to the feedwater. The flow of feedwater is counter to the flow of the combustion gases—a fact that contributes to the high fuel-to-steam efficiency of the Clayton Steam Generator units. The flow of feedwater supplied varies in relation to the firing rate of the unit, giving the unit a very consistent and high efficiency which does not decline with firing rate. Excess feedwater is supplied to the coil to assure good heat transfer and internal water circulation throughout its operating range.

A mechanical steam separator is then used to effectively separate the liquid and vapor mixture exiting the coil and provide consistent steam to your process—99.5% or higher quality in most cases.

This design offers many advantages over conventional units, due to its inherently low water volume. Among these benefits are:

  • Compact size and low weight
  • High fuel-to-steam efficiency
  • Rapid startup and excellent load following response
  • Low blowdown rates
  • High level of operator safety

Few environments place greater demands on men and machinery than offshore oil rigs. The weather can be extremely harsh. The work is demanding. Space is at a premium. And dependability is highly prized.Small wonder that more and more oil and gas exploration companies call for Clayton Steam Generators on their offshore oil rigs. These multi-purpose generators—available in a wide range of capacities—perform numerous important functions, such as:

  • Heating work floors
  • Desalinization
  • Heating rooms
  • Heating drilling fluids
  • De-icing
  • Cooking
  • General clean-up

But Clayton Steam Generators, used by major industries around the globe, are valued on offshore rigs for more than versatility. Compared with conventional steam boilers, the generators are notable for their compact size, light weight, low emissions and absence of explosion hazard. They are prized for their reliability, fuel economy and fully automatic PLC based controls, plus the ability to startup and follow load cycles quickly. And Clayton Steam Generators are backed by a world-wide support team of engineers and technicians to keep you online and in full production.
