Abstract

The invention provides a combined heat and power generation system. An exhaust steam regulating valve is arranged on an exhaust steam pumping pipeline and is in data connection with a programmable logic controller; a temperature sensor is arranged on a steam pipeline at the inlet of a steam-water heat exchanger; the temperature sensor is in data connection with the programmable logic controller and is used for measuring the temperature of steam entering the steam-water heat exchanger; and the programmable logic controller regulates the opening of the exhaust steam regulating valve by virtue of the steam temperature at the inlet of the steam-water heat exchanger. According to the system disclosed by the invention, the steam pumping quantity of exhaust steam and steam is automatically controlled according to the mixing temperature, so that the energy is saved, and the aims of environment friendliness and energy conservation are achieved.

Description

[0001] This application is a divisional application for the invention patent with the original application number 2014101475351 and the invention name is a radiator and a combined heat and power system including the radiator. technical field [0002] The invention belongs to the field of heat exchangers, in particular to a radiator in the field of combined heat and power generation, and belongs to the field of F28 heat exchangers and the field of F24D heat supply. Background technique [0003] Among the radiators, finned tube radiators are widely used at present. The heat dissipation area can be enlarged and the heat exchange effect can be enhanced through the fins. However, the radiator type of the finned tubes and the setting of the finned tube parameters all affect the cooling effect. Good or bad, and in the current situation of energy crisis, there is an urgent need to save energy and meet the sustainable development of society. Maximize thermal efficiency to save energy...
