Coil Type Steam Boilers

coil type steam boilers Incoming water is passed through economizer to absorb the heat from outgoing gas. Preheated water is circulated through coil shaped heat exchanger. more surface area will generate in high dryness fraction to the tune of 0.9 , this will results in extra enthalpy generation almost 1,00,000 kcal hr with compare to same capacity others design boiler for 600 kghr.
