Which fuels can be used with the generator?

Question

Accepted Answer

Clayton steam generators can be configured to operate on a wide variety of fuels, depending on availability and customer preference. Standard options include:

Natural gas
Light fuel oil (diesel)
Heavy fuel oil
Propane / LPG
Biofuels

In addition, Clayton offers dual-fuel burners, allowing automatic switching between gas and oil for maximum flexibility and security of supply. All Clayton burners can be hydrogen-ready and can operate on all common gaseous and liquid fuels. This makes the system highly adaptable for both today’s requirements and future energy transition projects.

To meet stringent environmental standards, Clayton can also supply burners with FGR (Flue Gas Recirculation), enabling very low NOx emissions while maintaining high efficiency.

With a fully modulating burner (turndown ratio up to 1:8), efficient operation is guaranteed across the full load range, no matter which fuel is used.

Feature	Quick Steam Generator	Steam Boiler	Clayton Steam Generator
Steam Quality	Wet steam. Low quality.	Moisture carryover increases during sudden demand.	Steam is 99.5% dry saturated, best available quality.
Quick Start Up	Short heat-up but high losses due to purging.	Up to 60 min startup time due to large water mass.	Startup within 5 min. Low heat requirement.
Rapid Response	Rapid but fluctuating pressures.	Lag limits flexibility.	Rapid adjustments without losing stability.
Safety	No info available.	Risk of steam explosion.	No explosions ever due to no large water storage.
Scale Control	Rapid scale build-up.	Scale forms easily, affects performance.	Easy detection, early corrective action.
Water Level Safeguards	Limited/unreliable safeguards.	Loss of water level can cause catastrophic failures.	No discernable water level, no controls needed.
Burner Operation	Frequent switching causes high fuel use.	Constant switching, high energy waste.	Fully modulating, off when no demand.
Maintenance	High wear and premature corrosion.	Corrosion repairs expensive.	Designed for low maintenance.
Steam Reserve	No steam reserve.	Limited reserve (~2 min).	Reliable pressure control, no issues.
Automatic Operation	Needs trained operators.	Supervision required.	Fully automatic, minimal human intervention.
Running Costs	No info available.	High running costs due to inefficiency.	High efficiency and lower running costs.
Space and Weight	Low space and weight.	Three times larger, up to 7x heavier.	Compact size, low installation costs.
Blowdown Losses	No blowdown, contaminants in steam.	Regular blowdown from entire water volume.	High tolerance, minimal blowdown.
