Shanghai Boiler Works Co., Ltd.

During long-time operation, boilers may have some safety issues and hidden troubles. SBW provides services such as pressure parts upgrade and optimization, anti-fouling/coking/abrasion/corrosion/vibration retrofits, and wall temperature deviation control, to ensure the safe and stable operation of boilers. Pressure parts upgrade and optimization includes four main pipes, platen superheater, FSH and FRH, which can ensure strength and durability of heating surface, and long term stable operation of boilers. Anti-fouling/coking optimization can reduce fouling and coking of nozzles and furnace by optimizing burner interior structure and reasonable air distribution. Soot blower configuration is optimized to ensure blowing effect. Heating effect is improved by small range of retrofits. Anti- abrasion/corrosion/vibration retrofits can be applied according to clients’ needs. Abrasion resistance of certain parts can be improved by installing wearing jacket. More specifically, installing anti-abrasion castables, comb-shape anti-abrasion board, anti-abrasion coating, etc. The retrofits are easy, direct and risk controllable. Wall temperature deviation can be controlled by testing and structure optimization, to avoid partly overtemperature. The above retrofits and optimization can effectively extend the service life of the boiler, reduce operation loss and eliminate hidden troubles.
