Abstract

The invention provides a cogeneration system. The steam extraction adjusting valve is arranged in a steam extraction pipeline between a steam turbine and a steam-water heat exchanger, is in data connection with a programmable controller and is used for controlling the amount of extracted steam. The amount of the extracted steam is adjusted according to the temperature, which is measured by a temperature sensor, of fed water of a heat exchanger; if the temperature of the fed water is over high, the amount of the extracted steam is reduced correspondingly; and if the temperature of the fed water is over low, the amount of the extracted steam is increased correspondingly. The extraction valve is adjusted intelligently according to detection temperature, the heat exchanging efficiency can be maximum, so that energy can be saved, and the purposes of protecting the environment and saving the energy 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...
