Abstract
A preheater (14) is used for boiler water and heat surfaces (16,18) for evapn. of water and superheating steam. To the preheater (14), for optimal regulation of the boiler water temp., is coupled a separate water circuit (21) so that in the preheater a water amt. circulates which is greater than the amt. of boiler water.
