Description
Technical Field
The present invention relates to a woody biomass micro gas turbine and a method for controlling the operation thereof, and more particularly to a heat supply/power supply type woody biomass combustion micro gas turbine capable of improving and more effectively utilizing woody biomass resources and a method for controlling the operation thereof.
Background
In recent years, biomass resources have been actively utilized from the viewpoint of reducing fossil fuel consumption. However, since the existence of biomass resources is relatively dispersed, a large amount of biomass resources are difficult to be intensively utilized in collection and transportation. Therefore, in order to more effectively utilize biomass resources, development of a small, low-capacity, and efficient utilization system is urgently required.
In a conventional generator using woody biomass as a fuel, steam is generated by a wood-burning boiler, and after a turbine generator is driven by the steam, the discharged steam is cooled and recovered as condensed water. By applying the steam cycle principle, the water is supplied to the boiler again.
However, in biomass power generation with a yield of 10 to 20 MW, the increase of steam temperature and pressure is limited, and the energy utilization efficiency is very limited, only between 10-15% utilization rate due to excessive heat loss caused by cooling water.
There have also been many efforts made by researchers, such as developing gasifiers for gasifying power generation systems, improving gasification efficiency, developing efficient tar removal and gas purification processes, and developing methanol synthesis liquefaction catalysts. . However, since the gasification process is complicated and an effective tar removal method capable of stably operating the gas engine generator cannot be obtained, a practical effect has not been achieved.
Disclosure of Invention
In order to achieve effective utilization of woody biomass resources, the present invention aims to design a small, small-capacity, high-efficiency biomass gas turbine system with a power generation efficiency of 20% or more and a total energy utilization efficiency of 75%, and to provide a highly reliable conventional biomass burner based on a thermoelectric supply device capable of achieving the above object even in a small-sized apparatus with a biomass yield of about 1 to 10 tons/day.
More specifically, the present invention uses woody biomass as fuel and is used in a thermoelectric supply device having a daily throughput of 1 to 10 tons or a annual throughput of 300 to 3000 tons, a power generation amount of 30 kW to 300 kW, and a power generation efficiency of 20% or more. The invention provides a woody biomass combustion micro gas turbine generator and an operation control method thereof, which can realize high-efficiency thermoelectric supply with the utilization efficiency of the whole energy of 70% or higher. The working fluid of a gas turbine is produced in a biomass-fueled steam boiler. Wherein the steam is mixed with compressed air from the microturbine and the generator is directly connected to the fluid.
The heat exchange sequence of the biomass fuel burner, the high temperature heat exchanger and the waste heat recovery boiler is started from the bottom in the cylindrical device main body. The timber biomass burner a comprises a pipeline, a micro gas turbine, a compressor and a micro gas turbine power generation device B which are connected through a driving connecting shaft. The compressed air stream is supplied to a high temperature heat exchanger and heated by combustion gases produced by combustion of the woody biomass fuel, and the high temperature compressed air stream from the high temperature heat exchanger is supplied to a micro gas turbine as a working fluid. In addition, the exhaust stream from the micro gas turbine is supplied as a combustion aid gas to a biomass fuel burner in the device body. While an auxiliary combustion burner is provided between the outlet of the compressed air stream of the high temperature heat exchanger and the working fluid supply port of the micro gas turbine, the auxiliary combustion burner heating the high temperature compressed air stream from the high temperature heat exchanger.
