FIELD: heating facilities.
SUBSTANCE: invention relates to method of utilization of heat abstracted in process of reduction of carbon dioxide. Proposed method includes cooling of outgoing gaseous combustion products in cooling tower 21, contacting of cooled combustion products in absorption tower 22 with regenerated absorbing liquid getting from regenerating tower 23. As a result, liquid with absorbed carbon dioxide is accumulated on bottom of absorption tower 22. Liquid with absorbed carbon dioxide is heated owing to heat exchange 35 with regenerated absorbing liquid from regenerating tower 23, heated liquid with absorbed carbon dioxide is delivered into regenerating tower 23, bottom of regenerating tower 23 is heat using saturated steam for separating liquid with absorbed carbon dioxide into carbon dioxide and regenerated absorbing liquid, after which separated carbon dioxide is discharge from regenerating tower 23 and recuperated. Return hot water is heated owing to at least one heat exchanger from group which includes heat exchange 37 with regenerated absorbing liquid after heat exchange, heat exchange 40 with carbon dioxide removed from regenerating tower 23 and heat exchange 44 with water saturated after heating of bottom of regenerating tower 23, thus obtaining hot water.
EFFECT: provision of large amounts of hot water at low cost.
