A steam boiler for neutralization treatment of concentrated steam water and condensation water

摘要

The present invention relates to a boiler having a boiler portion for heating water stored in a boiler tank to generate steam and supplying the steam to the outside, a replenishing water supply line connected to the heat exchanging pipe from the water supply pump, And a water supply preheater for supplying the preheated supplemental water to the boiler tank while the supplemental water flowing along the heat exchange pipe is heated by the heat exchange type by the heat of the exhaust gas passing therethrough and the boiler unit is provided with an alkaline concentration The steam preheater has a head portion to be assembled on an upper portion of the preheater casing. The head portion is formed in a lid shape having an open bottom and a gas outlet is formed in an upper surface portion of the head preheater. The side plate of the head part is connected to the end of the steam water discharge line, Is provided with a plurality of spray nozzles at a predetermined interval on the lower surface thereof. The concentrated steam from the steam water discharge line is sprayed downward through the spray nozzle, so that the exhaust gas from the boiler portion passes through the inside of the water heater The present invention relates to a steam boiler capable of neutralizing condensed water and dewatered water, characterized in that the acidic condensation water generated in the process of heat exchange is neutralized.
