2PVMC – Two passes of smoke steam boiler vertical execution marine with exhaust gas recovery unit

The steam generator mod. 2PVMC  is a single block generator with two smoke circuits, vertical execution.

It is provided with pressurized combustion and works fully automatically. It is supplied “packaged”: it is complete with all accessories. The supply includes the generator itself and the following auxiliary components:   

  • 1 primary feed pump
  • 1 electrical control panel
  • 2 level indicators
  • regulation and safety devices
  • valves and accessories

All these components are pre-mounted on the generator or on its base.

The generator basically consists of a boiler including the shell, pipe plates, the combustion chamber and the smoke pipes.
The shell is equipped with small blocks for steam intake, safety valves, the manometer, pressure gauges and a conductivity control probe, if necessary. There is also a maintenance hole, a handrail and lifting eyebolts.  The pipe plates (front and rear) are flat, welded on the plating and are provided with holes for inserting the smoke pipes.
The combustion chamber is cylindrical, open at the rear.
The smoke pipes, which are welded on the pipe plates, are located around the combustion chamber. 

The inside of the boiler and all accessories are accessible for cleaning and maintenance. They can be inspected both by users and the body responsible for controlling the generator. 

The unit is provided with all safety accessories, as established by the regulations in force.  

The pressure and the water level can be adjusted from the electrical panel which enables automatic operation. Three electrically and mechanically independent devices are used for controlling the make-up pump and signaling the lack of water.  

All devices are already connected with the hydraulic and electrical network. 

The exhaust gas recovery unit is designed for steam generation capacity based on available exhaust smokes flow and temperature.

Steam generation is usually designed at 85% MCR, in case of steam excess production a dumpin cooler is requested.

Standard design pressure: 12 bar
Boiler capacity from 1.000 kg/h to 5.000 kg/h
Bigger capacity and design pressure on demand
