Abstract

The invention discloses a gas co-generation technology optimizing system. The gas co-generation technology optimizing system comprises a power generation grid-connected system and a heat supply system. The power generation grid-connected system comprises a first control valve, a 1# heat exchanger and an expander, all of which are sequentially connected with a gas pipe network through a pipeline, and the output electric amount is at the positions where the expander and a micro-gas turbine are located. The heat supply system comprises a water supplementing system, an original industrial boiler and a heat exchange system, and the generated steam is at the positions of the heat exchange system and the boiler. According to the gas co-generation technology optimizing system, the economical scheme is provided for cleaning development and popularization of the industrial boiler, and gas supply safety of industry dispatching in the gas pipe network is guaranteed as well. The whole technology system is high in energy utilization rate and exergy efficiency and small in occupied area, adaptability to area type co-generation is high, and very high development potentials and application prospects are achieved.

Description

technical field [0001] The invention belongs to the field of gas heat and power cogeneration, and in particular relates to a gas heat and power cogeneration process optimization system. Background technique [0002] Cogeneration originally originated from the fact that a large amount of latent heat of condensation of low-pressure steam discharged from the steam turbine was taken away by the cooling water, and it was realized by increasing the back pressure or extracting steam to generate heat while generating electricity. The gas entering the gas gate station is generally high-pressure gas, but the pressure entering the downstream pipeline network is generally low-pressure gas, which means that the pipeline gas contains rich pressure energy, especially in large flow conditions. The pressure cannot be underestimated. [0003] With the blowing and continuation of the clarion call for energy conservation and emission reduction, coupled with the support of national policies and...
