Abstract
The invention discloses a power generation system with a circulating fluidized bed boiler. The power generation system comprises the circulating fluidized bed boiler, a main steam pipeline, a steam drum, a steam turbine and a power generator; a flue gas outlet of the circulating fluidized bed boiler is connected with the steam drum by the main steam pipeline, and an outlet of the steam drum is sequentially connected with the steam turbine and the power generator by pipelines. The power generation system has the advantages that the power generation system has application space in a large quantity of processes in the metallurgical and chemical industries, the energy utilization rate can be increased, and environmental pollution can be reduced.
Description
Technical field
The present invention relates to a kind of circulating fluidized bed boiler power generation system.
Background technique
Feature at China's present stage metallurgy due to high energy consumption (especially electricity needs is high), high pollution, is bearing huge pressure at antifouling reduction of discharging, the aspect such as energy-saving and cost-reducing.
In production link, boiler for producing can produce a large amount of high-temp waste gas, and the technique that many factories adopt is by accessing large-area radiator, makes flue-gas temperature be reduced to the temperature that dust collector can bear, last directly discharge.Only have minority residual heat resources for combustion-supporting air, pre-heat mixture or utilize waste heat recovering device to produce steam, heat recovery efficiency is on the whole not high.
For metallurgy industry enterprise, afterheat generating system investment is little, and instant effect, can significantly reduce energy consumption, improves Business Economic Benefit simultaneously, for the energy-saving and emission-reduction of China and the development of metallurgy industry, has very important meaning.Object of the present invention is just at a set of flue gas waste heat utilization of research and development.
Summary of the invention
The object of the present invention is to provide a kind of circulating fluidized bed boiler power generation system.
The present invention is achieved by the following technical solutions:
A kind of circulating fluidized bed boiler power generation system, comprise circulating fluidized bed boiler, main steam line, drum, steam turbine, generator, wherein the smoke outlet of circulating fluidized bed boiler is connected with drum by main steam line, and drum outlet is connected with steam turbine, generator successively by pipeline.
The waste heat that the present invention produces circulating fluidized bed boiler for generating, can reclaim heat after steam turbine, can reduce flue-gas temperature again.
The present invention has the space of application in a lot of metallurgical and chemical industry technique, can improve energy utilization rate, reduce environmental pollution.
Accompanying drawing explanation
Fig. 1 is structural formula schematic diagram of the present invention;
In figure: 1-circulating fluidized bed boiler, 2-main steam line, 3-drum, 4-steam turbine, 5-generator.
Embodiment
