Why Increase The Waste Heat Boiler Chloride

  • Why Increase The Waste Heat Boiler Chloride

    why increase the weast heat boiler chloride - WHGLA. High temperature corrosion in Waste Heat boilers. Flue gas recirculation could be used to recirculate and mix cool gases from the boiler exit with the hot incoming gasesthus reducing the gas inlet temperature to the boiler.However this increases the mass flow through the boiler and hence its initial cost.Operating costs are increased by
