Steam Generators

Clayton E Series Steam Generator.

Capacity in kW250 – 6000 kW
Steam production in kg/h9600 kg/h
Design pressureup to 60 bar
Fuelgas, light oil

The compact size of the Clayton steam generators see it normally fit in any available area while also reducing construction costs on new building installations. High efficiency which is inherent with the Clayton design translates into lower operating costs and improved overall system operation of the E Series. The E Series has a rapid response to changing steam loads. Clayton steam generators will automatically modulate to match your steam load profile while maintaining system steam pressure.

The once through design of the Clayton eliminates the possibility of a steam or water side explosion. The Clayton steam generator is simply the safest steam boiler on the market. Clayton’s design concentrates TDS blow down significantly which reduces wasted fuel, water and chemical costs. Full steam pressure and output in minutes from a cold startup saves fuel and labor cost over conventional designs. Eliminates wasted fuel from idling.

Operation is automatically controlled and the Clayton steam generator can be started from a single switch or remotely using an automatic start option. The relatively light weight means that all sizes of Clayton steam generators can be easily moved and installed even in areas with limited structural support.

Reliability of the Clayton steam generator is field proven and unsurpassed. This results in greatly reduced maintenance and attendance. Steam Quality in excess of 99.5% dry is assured at all times. This is the highest steam quality of any competitive design. Less water and impurities further increase your energy efficiency.

Waste Heat Boilers

The Clayton Waste Heat Recovery System can be used to generate steam or high temperature hot water. There are typical combinations of an exhaust gas or waste heat unit with a direct fired steam generator. A principal feature of the Clayton Waste Heat Recovery System is its unique coil design. The coil tube is wound in a spiral pattern with closely controlled spacing between turns. This provides the desired area to control the velocities of the boiler gases. This highly efficient heating surface arrangement minimizes size and weight requirements.

The Clayton Exhaust Gas Boiler (EGB) is primarily used in conjunction with a Prime Mover, such as a Turbine or Internal Combustion Engine (100 kW to 15 mW), as part of a Distributed Generation installation producing electricity or in marine/shipboard applications. The typical Clayton EGB is constructed of individual coil modules, with each module containing spirally wound layers.

The number of modules used depends upon the exhaust gas flows, allowable back pressure and on the boiler heat output requirements in steam or hot water. The Clayton EGB module is available in various sizes and configurations to meet individual requirements. Clayton EGB modules can operate at temperatures up to 650 °C and can run dry (without circulating water in the tubes) at temperatures up to 450°C. Once assembled with the appropriate coil modules, the completed Clayton EGB includes inlet and outlet cones that permit vertical or horizontal units with exhaust gas flows in any direction.

Electrode Boilers

Model CEJS

Capacity in KW

Up to 65,000 kW

Steam Production in kg/h

Up to 100,000 kg/h

Design pressure

7-34 bar


High-voltage electricity


The Model CEJS is a high-voltage, jet-type electrode steam boiler that utilizes properties of water to conduct electrical current and generate steam. The CEJS electrode boiler design includes a fully automated PLC that provides modulation and control to produce high volumes of steam. Simple to operate and maintain, all electrical energy is converted to heat. Automatic controls reduce the operating personnel requirements. No stack is required, with no emission of greenhouse gases.

Available in sizes ranging from 2 MW to 65 MW, with operating pressures from 7 up to 34 bar.


Biomass Boilers

Biomass fired installations are frequently supplied with fuels coming from Forests or sawmills. The size and moisture content of the fuel can vary considerably. The variability is critical in a network of heating installations where the fuel is supplied from various suppliers and sources.

The Biomass boiler has been designed and built to operate with solid fuels with a moisture content of up to 55%. The boiler can be supplied with 3 different types of combustion systems, which are; Model Biomass US with Under Feed Stoker for fuels up to 30 mm with a moisture content of up to 30% Model Biomass SG for fuels of up to 30 mm with a maximum moisture content of 55% utilising a screw fed Step Grate system of combustion.

Model Biomass LF for fuels 50 mm x 50 mm x 300 mm with a moisture content of up to 55% which utilises an hydraulic ram to feed the Step Grate system of combustion.

The boiler has been designed to produce Low Temperature and Medium Temperature Hot Water with operating pressures of 2 bar, 5 bar and 12 bar g. These pressures will allow operation temperatures up to 95 deg C, 130 deg C and 150 deg C respectively and designs conform to either EN 303 or PED as determined by the operating temperature required. The design of the boiler is essentially four passes, with two passes being completed within the combustion chamber and a further two passes in the gas passes of the heat exchanger. The large combustion chamber is a feature of the boiler creating high combustion temperature, long residence time in the furnace to ensure a quiet combustion process and low emissions. Whilst the models Biomass US and Biomass SG utilise screw feed for particle size up to 30 mm, the LF version using an hydraulic ram feeder system has been developed to accommodate larger sizes of timber up to 50 mm x 50 mm x 300 mm. The boiler control system incorporates user friendly software for reliability and ease of operation and control of the boiler system.
