ADVANTAGE

• Automatically laser cut and electrically welded boiler body constructed from high quality steel SA 516 GR 7.
• Front tube plate entirely flanged towards the furnace with full penetration face-to-face welding to the furnace (no T-butt weld), ensuring an efficient absorption of furnace expansion and an aerodynamic flue gas profile which eliminates the temperature concentration
• Furnace back plate fully dished (no T-butt weld) and submerged in the boiler water (wet back design), providing an efficient cooling of the furnace end plate
• Stay tube welded between the furnace back plate and the rear tube plate for a higher static resistance
• Dished rear tube plate to absorb the furnace expansion (from model HWT 300)
• Tubes to front plate unique assembly without projection of the tubes from the plate so as to avoid temperature concentrations
• Front door manufactured with steel plate and internally insulated with ceramic fibre, mounted on two easy-to-open hinges with reversible opening
• Rear smoke box manufactured in fireproof thermal insulated steel sheet, bolt mounted, complete with stack connection and cleaning door
• Radiation surfaces thermally insulated with thick glass wool - outer casing made of easy-to-mount painted steel panels
