Shanghai Boiler Works Co., Ltd.

To improve boiler efficiency and unit economical efficiency, SBW provides clients with various retrofits to create maximum economic value, including raising efficiency of burners, utilization of flue gas waste heat, raising temperature and capacity expansion, etc. The efficiency of burners can be raised by improving atomization effect of oil gun (adopting slight explosive atomizing oil gun), improving tangential firing technology, optimizing burner structure. The effect is obvious through small range of retrofits. Carbon content of fly ash of some coal is lowered than 1%. Flue gas waste heat can be recycled by installing low temperature economizer or air preheater bypass. Exhaust gas temperature can be lowered and effect on original system is slight. Raising of temperature and capacity expansion can be realized by retrofitting heating surface according to steam water parameter, heat absorption capacity change, boiler structure and operation condition, with high profitability. The above retrofits can increase economic benefits of units and create greater economic value for clients.
