Quick Steam Generators

Quick Steam Regenerator

Varor-D is the new generation of gas/oil fired 3-pass Steam Generator with 0.6 to 8 tn/h capacity of saturated steam at pressures up to 40barg.

Compact, easy to operate and maintain, ensures long-service life and safety during operation.

The Vapor-D is a once-through water-tube generator with a continuous monitoring of pressure & temperature of steam and modulating burner and feed water pump able to provide saturated steam at changing flow requirements.

The frequency converter modulates constantly the feed-water that is sent ot the coils in response to changes in steam pressure.

The servo control integrated on the burner, changes the amount of fuel and combustion air in direct propotion to the flow of water being sent to the coils. 99% of the water is converted into steam in the coils. Dry steam is then produced in the steam separator. The steam reserved in the steam separator is then further dried by the secondary steam dryer drum.

User Benefits you can rely on

Rapid start up from cold to full load in five minutes
Low cost coil replacement – multiple coil design permits replacement of only the damaged
High quality steam – guaranteed 99% + dry steam
Simplified fuel switching – only have to turn selector, no burner changes required
Low fuel requirments – air preheating and reftactory lined chamber for complete combustion
Minimum off-on cycling – turndown ration up to 10 to 1 for handling wide range of loads.
Quick response to load changes – cycle time of less than one minute.
