PURPOSE: A steam supplying and collecting system for a boiler in a sewage sludge waste treating facility is provided to improve energy consumption by efficiently supplying and recycling the heating source of a boiler. CONSTITUTION: A steam supplying and collecting system includes a boiler(110), a steam header(106), a soot blower(300), a pipe(77), a plume preventive heat exchanger(111), a drier(40), a condensed water tank(112), a deaerator(114), a boiler water supplying pump(115), an economizer(116). The soot blower receives steam from the steam header and transfers the steam to the boiler in order to eliminate soot from the boiler. The pipe is in connection with the steam header and transfers the steam to steam requiring places. The plume preventive heat exchanger dries exhaust gas in a wet type washing column and prevents the generation of plume. The drier implements an indirect heating operation through the pipe. The condensed water tank condenses wet steam from the drier. The deaerator deaerates the condensed water. The water supplying pump is in connection with the deaerator. The economizer is in connection with the water supplying pump and the boiler. |
