Detailed description

General

The boiler is of a conventional wet back design with a fully submerged rear combustion chamber giving full protection to tubes and tubeplates allowing full flexibility of the vessel during the combustion process.

The large furnace ensures complete combustion of both liquid and gaseous fuels. The furnace incorporates corrugated sections for larger boiler sizes, thus improving the flexibility of the boiler.

All materials used are certified to the latest European codes. Full NDT is carried out during construction using ultra sonic, radiographic and dye penetrant testing procedures.

The tube plates are butt-welded to tubes. T-butt welds to the furnace and shell are completely avoided.

The use of refractory materials has been mostly avoided, therefore, servicing operations are reduced to minimum and any dangerous thermal inertia is prevented.

Facilities for cleaning and inspection to the flue gas side of the boiler is gained via easy access opening doors.

Pressure vessel

Constructed from quality steel plate to standards P265GH UNI EN 10028/2 and P275NH UNI EN 10028/3

Welded and tested with methods approved and labeled CE in accordance with the PED 97 /23/EC directive

Front smoke chamber

The front smoke box is made from steel sheet, thermally insulated with refractory materials with a high aluminum content and supplied with a refractory cone to suit the burner.

Two flat separated front doors are manufactured from steel sheet and thermally insulated using a ceramic fiber panel, avoiding refractory material. They are fitted to the boiler by double pin joint hinges and can be opened without removing the burner. In this way the cleaning operations can be carried out by a single operator.

Combustion chamber

The combustion chamber incorporates corrugated sections for boiler size GX 2500 or larger, thus improving the flexibility of the boiler. The large furnace and gas reversal chamber provides for a low heat release ensuring complete combustion of both liquid and gaseous fuels.

Back smoke chamber

The wet back furnace has fully water-submerged rear smoke box. Made from steel sheet, thermally insulated with refractory materials with a high aluminum content.

Inspection / cleaning hatch

Horizontal or vertical chimney connection for integration with optional economiser

Flame inspection viewing glass with guillotine closing

Ø500 mm manhole port facilitates access to the combustion chamber for inspection and cleaning.

The two flat separated rear doors are manufactured from steel sheet and thermally insulated using a ceramic fiber panel, avoiding refractory material. They are fitted to the boiler by double pin joint hinges for smoke tube cleaning.

Smoke tubes

Smoke tubes are expanded and butt-welded into holes in the tube plates, which are drilled, reamed and dished. T-butt welds are completely avoided.

Smoke tubes are made in P235GH UNI EN 10216/2

The boiler works without turbolators, making it suitable for both gas and liquid fuels.

Connections

The boiler shell is equipped with manhole, hand holes, lifting eye bolts and welded, flanged PN 16 or PN 40 EN 1092-1 connections for boiler accessories.

Service deck

Upper walkway made from embossed metal sheet facilitates easy servicing of accessories and pipework located above the boiler.

Ladder and handrail available as option.

Support frame

The boiler support frame is built form carbon steel channel sections able to support the entire unit. Footprint includes cross members to maximise weight distribution.

Insulation and cladding

Thermal insulation provided by high density, 100 mm mineral wool mattress.

Round formed case with embossed aluminum cladding. Stainless steel cladding as option.

Control system and accessories

The boiler is supplied with electrically, mechanical and hydraulically assembled accessories needed for automatic operation. The safety control system is subjected to final functional tests and are certified in compliance with the PED 97 /23/ EC directive.

The electrical wiring is connected to a single centralized control board. It uses silicone insulated wires with PVC sheathing and complies with the strictest safety rules.
