PURAVION SteamTechnic V Series
Vertical-type coil steam generator, 750-2,000 kg/h · V750, V1000, V1500, V1800, V2000
Brand: PURAVION
The SteamTechnic V series is a vertical-type water-tube (coil) steam generator. Its low water volume means it reaches full power from a cold start within 5 minutes. The coil in the vertical body heats feed water in counter-flow against combustion gas; the manufacturer states 95% efficiency. All pipe joints are made with robotic welding. The feed water pump is German SPECK, control is a Schneider PLC, and switchgear components are Omron. The series includes five models: 750, 1,000, 1,500, 1,800 and 2,000 kg/h.
Features
- Low water-volume construction: the unit starts up within 2 minutes from a cold start, and the design itself reduces explosion risk.
- Robotic circumferential welding on all pipe joints, robotic tractor welding on flat surfaces.
- German SPECK feed water pump: resistant to cavitation.
- A Schneider PLC monitors pressure and temperature and adjusts burner output and water supply according to instantaneous demand.
- Operates with natural gas and diesel burners.
- All switching components are Omron.
- Optional cascade connection: several units operate together under shared control.
- The vertical construction takes up little floor space; it can be installed in container systems or directly next to the production line.
- Safety valves, level sensors and limit controllers back each other up.
- Touchscreen and integration with central control (SCADA/BMS).
- The external air jacket heats combustion air above 80°C — the manufacturer states approximately 1.5% savings.
- An economizer coil integrated into the body preheats the feed water.
- The dual coil increases the surface area in the combustion chamber and reduces heat stress.
- High-pressure feed water pump: a 3-cylinder, inverter-driven, dual ceramic pump system (2 × 2,400 l/hour).
- A pneumatic proportional control outlet valve prevents excessive steam draw-off and pressure drop.
- Programmable automatic start-up and automatic bottom blowdown.
- Ten-link redundant safety chain: flue temperature, steam temperature, inlet water temperature, water control, gas control, body temperature, operation control, safety control, flame control, safety valve.
- Steam temperature and pressure are controlled separately — the manufacturer describes this as fully saturated steam quality.
- Measurement of steam, water and gas flow; options for electrical conductivity, hardness and pH measurement.
- Modulating operation in the 30–100% range with an electro-pneumatic proportional control module.
