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
