Waste-heat boilers

That type EU waste heat boiler generates steam for processing and heating applications. It is a single-pass smoke tube boiler

 with an economizer unit; the flue gas flows horizontally through the smoke tubes, enters the economizer, from which it is discharged downward.

The boiler features the necessary control, monitoring and safety piping and instrumentation, as required by applicable laws and operating requirements.

The boiler has two self-priming pumps with a drive system, located directly by the boiler unit.  The feed water line is complete with the necessary valves and instruments. The boiler steam delivery line features a shut-off valve with a pressure gauge.

There is also a blowdown pipe with a fast-action valve, a drain pipe, safety valves, water gauges, starting valves, and a blowdown valve.
