Beschreibung
Zusammenfassung:	The invention discloses an adjusting method for heating steam of a cogeneration system, which belongs to the energy technical field, can improve the heat efficiency of a central heating system greatlyand can improve the heating efficiency of a heating unit. In the method, based on the corresponding reasonable use of the temperature of the heating steam of the cogeneration system, a heat supply network, a heat supply network heater and the hating unit are considered as an integral system, so as to provide the heating steam extraction parameter accurately and reduce the throttle loss in the heating process; the heating load of a heat user changes along with the change of the outdoor temperature, namely, the return water supply temperature of the heat supply network is changed, so as to change the steam extraction parameter of the heating unit; due to the associated coordination of the heat supply network, the heat supply network heater and the hating unit, the heating steam extraction parameter is matched with
