Unfired Clean Steam Generator – Steam‑to‑Steam Factory Solution
The unfired clean steam generator steam to steam factory is a purpose‑built unit that converts low‑grade waste heat or electrical energy directly into high‑purity saturated steam without any combustion chamber. Designed for continuous‑run process lines, it delivers reliable, on‑demand steam while eliminating emissions, reducing fuel costs, and simplifying plant permitting. Engineers and procurement managers choose this technology when a clean, compact, and highly efficient steam source is required for chemical, food‑processing, pharmaceutical, or petrochemical facilities.
How It Works – The Core of Unfired Steam Generation
Unlike traditional boilers, the unit contains no burners. Heat‑exchange tubes are immersed in a sealed, insulated vessel. Waste heat recovered from flue gases, engine exhaust, or solar‑thermal collectors transfers through the tubes, vaporising the feed water that circulates via a closed‑loop pump. A built‑in condensate‑return system recirculates condensate, maintaining water quality and minimizing make‑up water consumption. The entire process is monitored by a PLC‑controlled panel that regulates temperature, pressure, and flow, guaranteeing steam at 100 °C ± 2 °C and up to 0.6 MPa (≈6 bar) without any flame.
Key Benefits & Features
- Zero Combustion Emissions: Meets strict environmental regulations and eliminates the need for flue‑gas treatment.
- Energy‑Recovery Friendly: Accepts heat sources as low as 70 °C, turning otherwise wasted energy into usable steam.
- Compact Footprint: Up to 40 % smaller than comparable fired boilers, freeing valuable plant floor space.
- Fast Start‑Up: Reaches rated steam output in under 5 minutes, ideal for batch‑type processes.
- High Purity Steam: Closed‑loop design prevents oil carry‑over and guarantees ISO‑8573‑1 Class 0 water quality.
- Modular Design: Units can be paralleled for capacities from 5 t/h up to 200 t/h.
- Remote Monitoring: Integrated SCADA‑ready communication (Modbus/TCP, Profibus) for real‑time diagnostics.

Application Scenarios
The unfired clean steam generator steam to steam factory excels wherever a reliable, contaminant‑free steam source is needed without the logistical burden of fuel handling. Typical deployments include:
- Food & Beverage Processing: Pasteurisation, sterilisation, and cleaning‑in‑place (CIP) loops where steam purity is mandated by FDA and EU regulations.
- Pharmaceutical Manufacturing: Clean‑room steam for aseptic filling, HVAC humidification, and equipment sterilisation, meeting GMP standards.
- Chemical Synthesis: Reactor heating and reflux systems that benefit from rapid steam availability and low‑oxygen content.
- Petrochemical Refineries: Heat‑recovery integration with exhaust streams, providing steam for desulphurisation units without additional fuel.
- Power Plant Auxiliaries: Feed‑water pre‑heating and turbine‑driven steam‑blowers, reducing overall plant fuel consumption.
FAQ
What is the minimum order quantity (MOQ) for a customised unfired clean steam generator?
We accept single‑unit orders for pilot‑scale installations, but volume discounts start at a 5‑unit batch. All units are built to order, allowing full specification of capacity, pressure, and control options.
Can the generator be integrated with existing waste‑heat recovery systems?
Yes. The heat‑exchange module features standard flange connections (DN50‑DN200) and can be matched to any low‑temperature source, including exhaust gases, engine coolant, or solar‑thermal loops. Our engineering team provides a heat‑balance study to optimise integration.
What is the typical lead time from order to delivery?
Standard lead time ranges from 15 to 45 days, depending on capacity and optional accessories. Expedited production (7‑10 days) is available for urgent projects at a modest surcharge.
What warranty and after‑sales support are offered?
All units ship with a 24‑month comprehensive warranty covering parts and labour. Remote diagnostics, spare‑part logistics, and on‑site commissioning assistance are included in the after‑sales package.
