Manufactured solar nn steam-water in accordance with gost 28679-90 "heaters steam-heating systems. Construction and principle of the steam-water heater (pp) steam-water heater is used in heating, operating in temperature conditions 150-70, 130-70, 95-70 and serves to heat the heater nn network of water vapor for use in heating and hot water supply systems of various buildings. Represents steam water heater shell and tube heat exchanger is a horizontal type (heater PP), the basic units which are: * body * heater pipe system, heater * Front and rear (floating) Water heater chamber, the housing cover * heater. Assembling the basic units of steam-water heater paragraphs by using split-flange connections, providing the possibility of preventive inspection and repair heater pp. The heated water in the water / steam heater moves over the tubes, and heating steam through a pipe in the top of the heater Nos. enters the annular space heater in the which establishes the segmental walls, directing traffic flow in the steam heater pp. Heating steam condensate in heater water / steam flows into the lower part of the body and is discharged from the heater.
